Sample Sessions
The following sample sessions are common end-user configurations. They are provided as a guideline to better understand the possible
Remote Power On/Off system configurations. Each sample is preceded by the appropriate DIP switch settings; a brief outline follows.
1 2 3 4 5 6 7 8
ON
Power-ON Mode
Power-ON Ring 1; 2 minute Power-OFF delay.
Basic configuration for use with dedicated modem line. Power-off delay supports optional host software 'callback'
feature and/or PCs with lengthy bootup times.
1 The user places a modem call to the phone number of the line attached to the Power On/Off +Aux.
2 The Power On/Off +Aux unit detects the incoming RINGs and counts them. After the first ring, the Power On/Off
+Aux signals the IPM to power-ON the host PC and peripherals.
3 The calling PC waits (line continues to ring) as the host PC is booting. A command in the host PC's
AUTOEXEC.BAT file loads the host/communications software. The modem is initialized into answer mode.
4 The modem answers the incoming call, a connection is made, and the session begins. The Power On/Off +Aux sees
the OFF-HOOK condition and keeps the power ON for the duration of the call.
5 When the user is finished and the session is ended, the modems disconnect (hang-up) and the ON-HOOK condition
is detected. After a 2 minute delay, the IPM is signaled to power-OFF.
