Power
❏ Connect power, typicaly 13,8V from transceiver
Configure output driver
We available two types of output drive
Open collector
Using for components with grounding outputs
- Put in ULN2803A chip to U5 dil socket
- Set two jumpers in P2 to LEFT side
Open emiter
Using for components controlled with positive voltage
- Put in MIC2981 chip to U5 dil socket
- Set two jumpers in P2 to RIGHT side
- Connect power for output control to pin1 in J2 D-SUB connector| - this voltage use also for powered of band decoder and may be in range 8-24V
Configure outputs in firmware
- Allways enabled.
An entrance band data, or frequency, converts to output band 0-14 which can be configured in the following table - Preset Band to output matrix - in default settings Band-1 corresponds to Output-1, etc. You can sets any combination outputs for each band separately. With change zeros and ones in the Matrix table. Band-0 reserved for out of range inputs measure.

X,YYYYYYY\n
- X - band output in range 0-14, if activate BCD output range is 0-10 because 11-14 reserved for BCD. 0 (zero) = no output will be turned on.
- YYYYYYY - frequency in Hz - has no effect on the output relays, used if any CIV/CAT outputs activated.
- \n - is LF Line Feed (0A in hex)
CONFIGURE OUTPUTS
You can uncomment more than one output, but not all combinations are worked.
Always usable - may all at once.
- 8 output driver - allways enabled
- Yaesu BCD - allways enabled except activate Yaesu BCD input
- Serial echo
Only one from (not available during active Frequency request option (available only one TXD line)
//=====[ Outputs ]============================================================================================ // #define SERIAL_echo // Feedback on serial line in same baudrate, CVS format <[band],[freq]>\n // #define ICOM_CIV_OUT // send frequency to CIV ** you must set TRX CIV_ADRESS, and disable ICOM_CIV ** // #define KENWOOD_PC_OUT // send frequency to RS232 CAT ** for operation must disable REQUEST ** // #define YAESU_CAT_OUT // send frequency to RS232 CAT ** for operation must disable REQUEST **
8 output driver
- Allways enabled.
How to expand outputs
Band decoder use internal shift register with 8 outputs. This is free expandable. You can connect next shift register to P5 output connector. Schematics module for serial chain linkink on picture.
And sets number of all shift register in firmware
- internal = 1
- internal + one external =2
int NumberOfBoards = 2; // number of eight byte shift register 0-x
SERIAL ECHO
Activate uncomment line
#define SERIAL_echo
Requires setting
#define SERBAUD 9600

Always activate - except enable BCD input.
You can set rules to select BCD output, dependency to detected band input.
