1. 8 lead wire is connected between the same two boards This wire carries MIDI IN and OUT and optionally phantom power The remaining wire a longer 4 lead wire goes from LG FCB board to FCB1010 main board The LG FCB board has two identical 4 pins connectors Use the one which is in line with the 8 pins connector so the one closest to the edge At the other side plug the wire into the connector which was used by the original connector board You unplugged this cable in a previous step Finally in case you also have installed an expression pedal input board connect the small cable of that board with the remaining 4 pins connector on the LG FCB main board 1b 2b 3b 5 b e fe eN Boards overview top view inside FCB1010 housing A new connector board B original jack output board or new expression pedal input board C new LG FCB main board D original FCB1010 main board Connections overview 1a 1b USB between connector board and LG FCB main board 2a 2b MIDI power between connector board and LG FCB main board 3a 3b communication between FCB1010 main board and LG FCB main board 4a 4b original connection FCB1010 main board jack board 5 communication between LG FCB main board and optional expression pedal input board leave connector 5 open when not using the expression pedal input board The trickiest part is applying power As mentioned before we have 2 options using the original FCB2. the FCB1010 power cord This is the default way of powering the LG FCB board You just keep powering the FCB1010 as before using its mains cord connected to the back side In order to do so you need to connect the FCB1010 transfo output to the green LG FCB connector From there the power runs through the 2 jumpers to the shared power inputs of both boards which we wired in the previous step LG FCB board power input to power input FCB1010 board from FCB1010 transfo The transfo output is simply the other side of the 2 yellow wires which you cut previously They are too short to reach the green connector of the LG FCB board Therefore we have provided 2 short pieces of extension wire and a pinch connector which allows extending the 2 cut wires without need for a soldering iron One of the supplied cable ties can be used to strap the two floating connectors together after making the connections see picture 1 below Then you can attach the connectors to the housing using the second cable tie see picture 2 below so that everything is safely secured and no stress is applied to the wire connections Of course if you have the necessary tools you can also choose to make a soldered connection instead of using the 2 pinch connectors 6 3 Power connection when using phantom power As mentioned in the previous topics you can also choose to use phantom power supplied through the 7 pins MIDI connector In that case the FCB1010 no lo
3. 1010 power or using phantom power The LG FCB board has specific jumper settings to choose between both options In both cases we will need to interrupt the internal power leads in order to connect them to the LG FCB board cut at 3 7 5cm length AC power input FCB1010 main board FCB1010 transfo AC mains input The two original yellow wires carrying the low voltage AC power for the FCB1010 main board will be interrupted in order to supply power for the LG FCB board too or else in order to eliminate the built in transformator and apply phantom power from the MIDI connector instead The 2 options will be shown in more detail on the following pages topic 5 2 and 5 3 LG FCB board jumpers to choose to power FCB1010 board b phantom power from s a power from 7 pins MIDI connector km s eG i FCB1010 transfo Above schematic shows you all possible power connections Phantom power can be applied through the MIDI connector and enters the LG FCB board through the 8 pins cable From there it runs to the 2 jumpers as one of the possible power sources The cut wires coming from the FCB1010 transfo enter the LG FCB board through the 5 pins spring terminal block and go to the other side of the 2 jumpers as alternative power source The middle contacts of the 2 jumpers will contain the chosen power source and are routed both to the power input of the LG FCB board and through the 5 pins spring
4. 5 pins MIDI cable for supplying phantom power plus MIDI OUT This option was covered in chapter 3 it involves changing 2 jumper settings on the small connector board but it also requires the connected gear to support this type of wiring 7 Done This finalizes the upgrade of your FCB1010 with the LG FCB upgrade kit Now you can switch to the second manual covering the use of LG FCB ControlCenter and the full functionality of the extension kit Good luck
5. CB1010 on top of one of the large switch electronics boards At one side it connects to the original FCB1010 main board to receive click events and control the LEDs and display At the other side it connects to the outside world through the newly installed connector board Jumper settings The LG FCB board contains 2 adjacent jumpers which are related to the optional use of phantom power Indeed you have 2 options for powering the board One possibility is to reuse the FCB1010 power With this option you simply keep powering the FCB1010 as you did before through the mains lead connected to the back of the floorboard The LG FCB board is connected to the internal power leads as described in detail in a next chapter To use this option simply keep the 2 jumpers on their original position see left side picture below A second option is to use phantom power This option allows you to apply power to the LG FCB board through the 7 pins MIDI connector This connection can not only power the LG FCB board itself but also the FCB1010 electronics This means that you no longer need to plug in a power lead at the back side of the FCB1010 Just connect a 9V AC or DC adapter at the other side of your 7 pins MIDI cable and then this MIDI cable is the only cable running to your floorboard In order to use this phantom power option move the 2 jumpers to their alternate position right side picture below See the chapter about making the connections fo

Extending the FCB1010 with the LG FCB upgrade kit This manual covers the upgrade procedure for the LG FCB upgrade kit A separate user manual is available with detailed info about the functionality provided by the kit and how to program it using LG FCB ControlCenter The upgrade is shown in a small series of videos available on YouTube Here are the links http www youtube com watch v SH1VJJxa7yw http www youtube com watch v qKggvYpDmMAM http www youtube com watch v UvS2vfm_ Vk the upgrade kit contents 1a LG FCB connector board contains a USB connector and a 7 pins MIDI connector 1b LG FCB main controller board the brains of the upgrade 2 special FCB1010 firmware for 2 way communication with LG FB board 3a 4 screws to install the main board 3b 2 metal hex spacers and 2 plastic spacers for mounting the main board 4a USB connection cable between connector board and main board 4b Power MIDI connection cable between connector board and main board 4c Communication cable between FCB1010 main board and LG FCB main board 5 Cable ties to attach the internal power connectors and leads 6 2 solderless connectors with wire for connecting FCB1010 power with the LG FCB boards ees the ultima in MIDI control in MIDI contr The FCB1010 after upgrading The optional expression pedal input board Along with the upgrade kit shown above you can also install an optional expression pedal input board The new board w
8. MIDI cable and treat the 7 pins connector as a regular MIDI OUT If however you do need extra MIDI IN capability for adding more MIDI devices earlier in the MIDI chain you will need to make a conversion cable to go from two 5 pins IN OUT connectors to one single 7 pins using the pinning info above Jumper settings On the connector board you will see 2 jumpers When you leave them on their original position you will have all MIDI IN MIDI OUT phantom power functionality described above Both jumpers can be moved to the alternative position in one specific scenario if your connected MIDI device supports this you can use pins 1 amp 3 of the connector for applying phantom power instead of using the default pins 6 amp 7 This allows you to use a regular 5 pins MIDI cable instead of a less common 7 pins cable In this scenario no MIDI IN functionality is available pins 1 amp 3 MIDI IN default Pins 1 amp 3 phantom power Attention in order to avoid damaging your gear do not use this alternative wiring unless you are sure that the connected device supports this Also if you want to use a 5 pins cable for both MIDI and power make sure that the used cable has all 5 pins wired Since the MIDI standard only uses 3 of the 5 pins many cheaper MIDI cables have only 3 pins actually wired The same is true when using a 7 pins cable for both MIDI IN and MIDI OUT along with phantom power Pins 6 amp 7 of such cable are always wired h
9. hich connects to the LG FCB main board using a small 4 wire cable is mechanically compatible with the original jack board so replacing the board is very simple More info about this board is given in topic 4 of this manual new input board installed next to the connector board 1 Opening the FCB1010 housing Lay the FCB1010 upside down on a soft surface disconnect the power cord and remove the 16 black screws which hold the bottom cover Now you can flip the bottom plate over in order to access the FCB1010 internals Attention the bottom plate is still connected to the housing with a ground wire but you can flip it over without disconnecting this wire the 16 screws to remove the opened housing with ground wire attached 2 Upgrading the FCB1010 firmware EPROM Why With the LG FCB board installed the original FCB1010 functionality is replaced with the extended LG FCB feature set One of the advantages is that the LG FCB firmware can be easily updated through USB which is not the case with the original FCB1010 firmware To accomplish this the original FCB1010 firmware is replaced with very basic firmware which turns the FCB1010 into a slave for the LG FCB board All switch clicks are simply forwarded to the board and all control over the switch LEDs is taken over by the LG FCB board The FCB1010 slave firmware EPROM which accomplishes this is included in the upgrade package How Behringer provides following P
10. nger requires a power cord Just connect a power adapter to the rack end of the MIDI cable Make sure the adapter supplies 9V AC or DC and a minimum of 650mA The power will run through the MIDI cable and enter the floorboard through the new connector board It will power both the LG FCB board and the FCB1010 electronics thanks to the connection we established in topic 5 1 above No extra connection is needed so you can simply secure the 2 dangling yellow wires coming from the FCB1010 transfo and isolate both loose ends with tape to make sure they cannot touch any circuit or make a short this is of course very important In order to use this phantom power option move the 2 jumpers on the LG FCB board to their alternative position as depicted below see also the picture about jumper settings in chapter 4 LG FCB board power input to power input FCB1010 board phantom power from 7 pins conn One of the commercially available MIDI cables which can be used for this phantom power scenario is the Rocktron 5 7 MIDI cable It has a 7 pins connector at one side which plugs into the modified FCB1010 and a regular 5 pins MIDI OUT connector at the other side along with a female power jack which can be used to connect your power adapter 6 4 Phantom power through a regular 5 pins MIDI cable While we are covering this topic of phantom powering the modified FCB1010 let me remind you that there is a possibility to use a regular
11. on pedals instead you can install the optional expression pedal input board This board digitizes any regular expression pedal and the LG FCB board converts the pedal sweep into a continuous stream of MIDI ControlChange messages Adding this interface board gives you 4 independent expression pedals 2 external ones next to the 2 internal expression pedals of the FCB1010 Each of the 4 pedals can manage a different setting of the MIDI controlled device As you can read in the manual of the LG FCB editor each single expression pedal can even control multiple settings simultaneously each with a different programmable sweep range The expression pedal settings can be programmed globally for all presets or individually for each preset How Installation of the expression pedal board is very straightforward It is mechanically compatible with the original FCB1010 jack board so you can simply remove the original board by removing the 2 nuts and disconnecting the internal cable which plugs into the FCB1010 main board and replace it with the new board reusing the washers and nuts of the original one The short cable of the new input board will plug into the LG FCB main board Once that board is installed it will be obvious which connector to use for this see also the topic about Making the connections further below 5 Installing the LG FCB board What The LG FCB board is the new brain of your floorboard It fits inside the F
12. owever some 7 pins cables don t have pins 1 amp 3 wired And one last obvious remark always move both jumpers simultaneously and keep them aligned never mix 2 settings one left one right How Installation of the electronics is shown in the second video mentioned at the start of this manual The small LG FCB connector board is an easy replacement of the original connector board It reuses the same 2 black screws for mounting You will need cutting pliers when removing the original connector board it has a small ground wire soldered to another board which you can simply cut In order to unplug the connector from the main board you might need to remove some hot glue on the connector first Be careful not to damage the board or the connector while doing so Later on we will reuse this same FCB1010 main board connector for connection with the LG FCB board L T pern a ven 1 re u oan ee ee mounted connector board inside view mounted connector board outside view 4 Installing the optional expression pedal input board What The FCB1010 has 2 switch output jacks for controlling non MIDI enabled amplifiers Two internal relays can close or open the contacts on the jacks It is easy to confuse this with jack inputs which you find on many other MIDI controllers and which can be used to connect external expression pedals If you are not interested in the jack outputs but would prefer 2 jack inputs for expressi
13. r a schematic drawing of the 2 powering options reuse FCB1010 power supply phantom power Remark always install both jumpers in the same position either left or right as shown in the pictures above Never mix 2 different jumper positions as this might result in a damaged power adapter and or FCB1010 transfo Remark the additional jumper which you can see in the background at the left side of both pictures is used for factory testing purposes only Its position should never be changed How You can reuse 4 existing attachment points to mount the LG FCB board 4 spacers are included in the upgrade kit 2 hex spacers replace 2 hex nuts 2 plastic spacers are mounted reusing the original screws The picture below indicates the exact location of the 4 attachment points LG FCB main board attachment points close up backside view The special white plastic spacers are used to map the board mounting holes with the original mounting points As shown in the second video mentioned at the beginning of this manual you can first position the board and use its mounting screws to find the optimal placement angle of the 2 white spacers Then remove the board again and fasten the spacers on their correct position before installing the board permanently 6 Making the connections Now we can insert all cables supplied with the upgrade kit A short 4 lead wire goes from connector board to main board It carries the 2 way USB signal Next an
14. s started correctly with the upgraded firmware 3 Installing the new MIDI USB connector board What One of the most interesting add ons of the LG FCB board is its USB capability You can now download setups and even firmware updates through USB The original FCB1010 is depending on third party MIDI USB interfaces which regularly turn out to be incompatible with the SysEx messages used by the FCB1010 In order to avoid difficult modifications of the metal housing we decided to replace the 2 original MIDI connectors with one USB connector and one 7 pins MIDI connector The 7 pins connector combines MIDI IN MIDI OUT and phantom power functionality It is compatible with a regular MIDI OUT connector while 2 of the normally unconnected pins are now used for MIDI IN The 2 extra pins can optionally be used to apply phantom power Details about the connector pinning are shown in the drawing below Details about phantom powering are covered in a later chapter GND GND 2 2 2 MIDIIN source 4 5 MIDIIN sink MIDI OUT source 4 5 MIDI OUT sink MIDI OUT source 4 5 MIDI OUT sink 1 3 1 3 MIDIIN source 1 3 MIDI IN sink o phantom power 6 a 7 phantom power regular MIDI IN connector regular MIDI OUT connector combined MIDI power connector The regular FCB1010 required a MIDI IN connection for doing patchdumps from computer Since the LG FCB board has USB for this you probably won t miss the MIDI IN connector Just use a regular 5 pins
15. terminal block to the power input of the FCB1010 board 6 1 Interconnecting power of the 2 main boards First of all we need to interconnect the power input of the LG FCB board and the FCB1010 main board We do this by cutting the 2 yellow power leads which run from FCB1010 transfo to the FCB1010 main board they carry a low voltage something like 9 VAC Don t worry our modifications will never interfere with mains voltage Cut both yellow wires at about 3 7 5cm measured from the main board Now you can connect the 2 smallest ends coming from the FCB1010 main board with the LG FCB board using the big green spring terminal block Strip both wires and insert them in the 2 rightmost contacts of the green connector the contacts closest to the FCB1010 main board Since the wires carry AC voltage which doesn t have a polarity it doesn t matter in which order you connect the wires as long as you use the 2 rightmost contacts Even when using DC phantom power the polarity is still irrelevant since both connected boards have a rectifier circuit which can handle both DC polarities The connections with the terminal block are easy to make Take a small screwdriver and use it to push the small plastic handle next to the contact firmly Then guide the wire into the contact hole and release the handle The wire will now be pinched into the contact pull it to check that you have a firm connection 6 2 Power connection when using
