Power-ON Mode
The default operating mode for the Remote Power On/Off system is the Power-ON Mode. This mode allows a PC and peripherals to be
turned-ON by an incoming telephone call and automatically turned-OFF after the call is completed.
In this mode, the Power On/Off +Aux control unit monitors the telephone line for three conditions known generically as RING, OFF-
HOOK, and ON-HOOK. The system will react as follows:
RING: When a call is placed to the unit, each incoming RING is counted and, after a selected ring number, the power-
ON signal is sent to the IPM.
OFF-HOOK: The power-ON signal to the IPM will endure as long as RING(s) continue or OFF-HOOK exists (the call has
been answered).
ON-HOOK: When hang-up occurs, the ON-HOOK condition is detected. After a selected delay, the power-OFF signal is
automatically sent to the IPM.
NOTE: When operating the PC locally, the Master ON/OFF switch must be used to power the system both on and off. In such cases,
when the PC is powered-ON locally by the push button, incoming calls will never alter the ON state unless the 15-Ring Turn-Off option
(described later in this section) is enabled.
Power-ON Mode Options
Power-ON Ring Number - This option sets the number of RINGs after which the Power On/Off +Aux control unit
sends the power-ON signal to the IPM. The default is one (1) RING. Optional settings are five (5), or ten (10) RINGs.
The five or ten ring options are useful as an added security feature (so that the PC will not power-ON with every call) or
to allow voice or non-modem calls to be answered prior to the power turning on.
Power-OFF Delay Time - This option sets the delay time that the control unit will wait, after ON-HOOK (hang-up) is
detected, before sending the power-OFF signal to the IPM. The default is to send the power-OFF signal one (1) second
after ON-HOOK is detected, so long as the Minimum-On-Time has expired. Optional settings are two (2) minutes, 15
minutes, and one (1) hour.
