1. SAK 232 Quick User s Guide Manual control Sumary of manual modes F1 manual movement indicated by a horizontal bar in upper left corner of the display F2 zero position allows to assign a zero position like a north direction at any physical position of the rotor F3 soft limits when in the F3 mode simultaneous press of both E and W buttons starts a procedure of automatic limits search however the rotator must be equipped with its own hard limit switches F4 factory settings press both E and W buttons simultaneously when in the F4 mode to recall factory settings F5 gear ratio when in the F5 mode first with E and W buttons select number of pulses and confirm with the P button then in a similar way select and confirm number of degrees equivalent to the selected number of pulses Note use the following gear ratios for RAU and RAK rotors from Zelpro RAU 6 pulses 4 degress RAK 4 pulses 4 degress To select one of the above modes press the P button and hold it until a symbol of the required mode is displayed Usual way of configuring your SAK 232 is setting gear ratio of your rotator first F5 and then setting soft limits F3 Rotor should be connected with its 4 wires according to MOTOR and PULSE labels on the rear side of the SAK 2372 Stored positions There is a possibility to store of up to 199 pre programmed positions for easy later recall To enter into this mode press and hold P an2. d then immediately W Storing positions enter the F1 mode indicated by a horizontal bar in the upper left corner move your rotor to the required azimuth using E and W buttons press and hold P for approximately 1 5 seconds the display will start blinking select required position number using E and W buttons press P to accept the display starts blinking faster press and hold P again the display stops blinking and the position is stored Computer control The SAK 232 is equipped with a standard RS 232 serial interface which you can connect to any PC Note If your computer does not have an RS 232 interface you can use its USB interface with a USB to RS 232 converter Ask for one at your local computer store The RS 232 settings are 9600 8N1 no handshake which details to Baud rate 9600 bps Word length 8 bits Patiry bit no Stop bits 1 XON XOFF no RTS CTS no The SAK 232 can cooperate with many programs for hams amateurs having possibility to control rotors One of such programs is LOGGER http www kc4elo com To use this program configure it to use a Yaesu rotor Config gt Rotor Type gt Yaesu GS 23 GS 232 and configure available RS 232 port to the settings given above Config gt Rotor Port You can also use any terminal program HyperTerminal is one of such programs It is available in standard distributions of MS Windows family of operating systems Use the commands given in the be
3. low command reference Each command should be terminated with lt ENTER gt key Command Reference Each of the below commands consists of a command code being a single capital character The command may be followed by one or more parameters The parameters are separated by lt SPACE gt Each command is terminated by lt ENTER gt A aaa Move to a required azimuth given by the aaa number aaa should be a number between 0 and 359 K Automatically find and store limit positions of the rotor Requires the rotor to be equipped with hard limit switches O aaa Orientation assign a real known azimuth to the current position of the rotor aaa denotes a number between 0 and 359 P pp ddd Set gear ratio pp number of pulses a number between 1 and 999 ddd number of degrees a number between 1 and 24 ddd must not be greater than ppp not less than one pulse per degree pp ddd must not be greater than 24 not more than 24 pulses per degree A gear ratio is an individual parameter of any type of rotor and indicates how many pulses of its internal pulse switch are required to move by a specified angle expressed by degrees Example by issuing a P 5 3 command you specify a rotor which generates 5 pulses ber each 3 degrees of its rotation move R ddd Relative move Move by ddd degrees relative to the current position ddd may be a positive or negative number with its sign indicating direction of move If ddd exceeds programmed
4. soft limits or rotor s hard limits then actual move is made to that limit only Examples R 12 move right by 12 degrees R 45 move left by 45 degrees Stop Immediate unconditional stop of any move in progress Manufacturer http www zelpro com pl
