1. nearest PC 104 Connector The radio module is now powered from the PC 104 bus an no further connections are required It is important to be sure that the 12 VDC bus power source has sufficient current to supply the radio It is recommended that the supply have at least 1 0 Amp capacity External Power Place jumper JP3 in the EXT position jumper farthest from PC 104 Connector The radio power now comes from terminal block J4 Note polarity The positive terminal is marked with a and is the terminal farthest from the PC 104 Connector Be sure to tighten the terminals snugly The radio can be powered from any 6 30 VDC source such as vehicle power as long as the source is capable of at least 1 Amp Caution Observe polarity when powering radio from external power When using external power sources for the radio modem it is essential that the external radio power and PC 104 stack be switched at the same time as described earlier in this manual It is recommended that if vehicle power is used the radio and PC 104 stack be switched from the same master power switch Powering the radio and not the stack could potentially damage either the radio or the stack Similarly powering the stack and not the radio can also potentially cause damage Setup Switch In order to access the FreeWave Radio setup menus it is necessary to drive the setup line on the radio low This can be achieved two ways One the PCFW 104 incorporates a setup switch Pre2. F Shield Once the unit is configured and installed it is treated like any other serial port on the stack In other words if it is configured for an address of 3F8 and IRQ 4 then it is as simple as using any device on COM 1 The interface supports baud rates up to a maximum of 115 200 The unit includes the 16 bit ISA connector so 16 bit devices can be placed on the stack after the radio Also interrupts 10 11 14 and 15 are accessed thru this connector The PCFW 104 being an 8 BIT interface does not require a 16 bit ISA card be prior to the radio unless operation requires IRQ 10 11 12 or 15 For more information on the PC 104 ISA bus please refer to the PC 104 specification at http www pc1 04 org technology PDF PC1 04Specv246 pdf Operation This unit is extremely easy to use and incorporates three jumper sets JP1 JP2 and JP3 The PCFW 104 contains static sensitive CMOS components The greatest danger occurs when the card is plugged into the PC 104 stack The card becomes charged by the user and the static discharges to the I O bus from the pin closest to the card connector If that pin happens to be an input pin even TTL inputs may be damaged Follow sound ESD practices To avoid damaging your card and its components 1 Ground yourself before handling the PCFW 104 Radio Modem 2 Disconnect power before removing or inserting the PCFW 104 Radio Modem OPERATING PRECAUTIONS Be sure that your PC 104 stack and or power sup
3. MicroBee Systems against all damage Please read before installing your product MicroBee s products are designed to be high in performance while consuming very little power In order to maintain this advantage CMOS circuitry is used CMOS chips have specific needs and some special requirements that the user must be aware of Read the following to help avoid damage to your card from the use of CMOS chips Using CMOS Circuitry Industrial Control originally used LSTTL circuits Because many PC components are used in laptop computers IC manufacturers are exclusively using CMOS technology Both TTL and CMOS have failure mechanisms but they are different This section describes some of the common failures which are common to all manufacturers of CMOS equipment Improper power causes catastrophic failure If a card has had reverse polarity or high voltage applied replacing a failed component is not an adequate fix Other components probably have been partially damaged or a failure mechanism has been induced Therefore a failure will probably occur in the future For such cards MicroBee highly recommends that these cards be replaced Other over voltage symptoms In over voltage situations the programmable logic devices EPROM s and CPU chips usually fail in this order The failed device may be hot to the touch It is usually the case that only one IC will be overheated at a time Power sequencing The possibility of failure can be cause

5. d by the external application of input voltage to the radio via the external B input while the PCFW 104 power is off If you apply 5V to the input of a TTL chip with the power off nothing will happen Applying a 5V input to a CMOS card will cause the current to flow through the input and out the 5V power pin This current attempts to power up the card Most inputs are rated at 25 mA maximum When this is exceeded the chip may be damaged Failure on power up Even when there is not enough current to destroy an input described above the chip may be destroyed when the power to the card is applied This is due to the fact that the input current biases the IC so that it acts as a forward biased diode on power up This type of failure is typical on serial interface chips Hot insertion Plugging cards into the card cage with the power on will usually not cause a problem MicroBee urges that you do not do this However the card may be damaged if the right sequence of pins contacts as the card is pushed into the socket This usually damages bus driver chips and they may become hot when the power is applied This is one of the most common failures of expansion cards PREFACE This manual is a guide to the proper configuration installation and operation of your PCFW 104 Interface For setup and operation of the FreeWave FGRM Radio Modem refer to the FreeWave Radio Users Manuals included with this product You can use your PCFW 104 card in conjunctio
