7.2 Telephone Commands
6712 controllers equipped with an internal voice modem can be
operated using telephone commands. This factory-installed
option includes a 12 ft (3.6 m) modem cable.
After connecting to the sampler from a touch-tone telephone,
command numbers may be entered from the telephone’s keypad,
followed by the
(pound) button. The commands are listed in
Table 7-4.
To use telephone commands:
1. Dial the sampler’s telephone number. When the sampler
connects, it answers with “Teledyne Isco Sampler Site
[number].” If the sampler does not receive a touch-tone
command in five seconds, it assumes that a computer
modem has called and initiates the modem connect
sequence. If this occurs you must hang up and try again.
2. Enter the command. For example, to run program 1, press
.
3. If the command is valid for its current state of operation,
the sampler responds with “[command number], please
acknowledge.” If the command is not valid the sampler
responds with the command number followed by three
quick beeps. Enter a valid command.
4. Acknowledge the valid command by pressing the number.
For the example, press .
5. If the number is incorrect, the sampler responds with your
entry followed by three quick beeps. You must re-enter the
command (step 2).
6. After the command is confirmed, the sampler replies with
“[command number] acknowledge” and executes the com-
mand.
To enter additional commands, repeat steps 2 through 5. The
sampler will hang up after ten seconds of quiet time.
