Batboard

anyone have a picture of pin outs on desktrac for say hooking up remote

.

Accy 1 connector is labeled remote control line connector:
1. LINE 1
2. LINE 2 <both are for 2/4 wire TX

3. LINE 3
4. LINE 4 <both are for 4 wire RX

Pins 5,6,7,8 are internal connections only, do not use.
I think u have to set jumpers to tell it if you're using 2 or 4 wire setups... anyone??

Accy 2 connector pins are labeled Phone patch, paging encoder, rptr panel, extended local deskset and pins are:

1. Accy ground
2. n/c
3. B+ <13.8v, 750mA>
4. PTT TEL, <active low logic>
5. MIC TEL
6. GND
7. DRXA TEL <rx audio to phone patch>
8. GND
9. CHM, alert inhibit <CSQ logic output, active low logic>
10. B+ <same as Pin 3> Tel inhibit
11. n/c
12. PL CHM TEL, (unsquelch), coded squelch logic output, active low.
13. PTT <active low>
14. LINE PTT <ptt i/o parallel to ptt from remote interface board, active low> used by BSC.
15. DRXA EXT LCL, amp-ed rx audio for extended local desk set.
16. TXA EXT LCL, tx audio from local ext. desk set.
17. CTCSS <tx ctcss from rptr panel, flat audio input>
18. MON EXT LCL <monitor logic momentary input from lcl dsk set, active low>
19. PTT EXT LCL <keys tx and allows ext lcl audio, active low>
20. RPTR DIS <rptr disable, active low>
21. TX PL INHIBIT
22. TXA <tx audio from rptr panel, flat audio>
23. TXA <rx flat audio for rptr panel>
24. PTT PAGER <keys tx, allows pager audio to tx, active low, doesn't allow pre/post id signalling.
25. MIC PAGER <tx audio from paging encoder>
*****

Accy 3 is for audio out:

Pins 11 and 24 are tied together for speaker audio HI
Pins 19 and 18 are tied together for speaker audio LO
