When using the PB-100 as a telecom controller without the included software or with your custom software, place DIP
switch 1 on the front panel in the “on” (up) position. This inhibits the unit from sending 1600 polling tones. The PB-100
accepts a simple set of ASCII commands as follows:
D, xxxx...<cr> Dial the number string “xxxx....”
Response is K<cr>
H<cr> Hang up
Response is K<cr>
A<cr> Abort call in E-1600 mode
Response is K<cr>
N<cr> Request touch tones four at a time
Response is NONE<cr> if four tones not received else XXXX<cr>
where x is the ASCII character of the tone
R<cr> Read single touch tone
Response is rx<cr> where X is the ASCII character of the tone or
r<sp><cr> if no tones are available
V<cr> Switch to Audio mode
Response is K<cr>
Gxxxx...<cr> Dial the number “xxxx...”, wait for carrier, then go into the transmit mode
Response is K<cr>
S<cr> Request status
Response is S(status)<cr> where status is one bite as follows:
T,(28 data bytes),cs,<cr> Transmit 28 data bytes with check sum
Response is N<cr>
O<cr> Watch for 2 seconds of carrier then switch to transmit mode
Response is K<cr>
C<cr> Grab line, send carrier tone for 2 seconds, then switch to receive
Response is K<cr>
I<cr> Read modem data, 28 bytes at a time with check sum
Response is (28 bytes of data), cs,<cr> where cs is the check sum
F<cr> Force modem carrier back on in the transmit mode
