POWER CONTROL
The A/C power is controlled by a few simple codes sent to Pal. In all cases, Pal responds with tones to confirm
commands and to report the current status of the power. If invalid codes are sent, Pal responds with a low ‘Error’
tone. Power can only be controlled on calls placed to Pal. During outgoing calls, Pal is totally transparent,
allowing any phone numbers to be dialed without risk of accidental power control.
Status
Once Pal Answers the call, the caller sends a command control code to Pal. This code must be sent during the
quiet portion of Pal’s answering sequence.
When Pal is answering a call, with security level 0 enter:
1
With security level 1 or 2 enter the security code (see programming section # c
∗
)
Pal will respond with the current power status:
One Beep = Power OFF
Two Beeps = Power ON
Once the current status is reported the caller can control the power. Power can either be changed, On or Off, or a
Power Reset can be done.
Change Power
To Change Power Enter:
This Toggles power from On to Off or Off to On. Pal will respond with the new status. Power On (Two Beeps),
Power Off (One Beep). The Power Change command can be entered as many times as necessary.
Power Reset
To Power Reset Enter:
Power Reset will pulse the power for a set time. The length of the pulse is user programmable (5-45 sec.). When
Power Reset is commanded, Pal first reports status at the start of the pulse, then again after the preset time.
(During reset all commands are ignored until completion.)
Status Request
To find out the current status of the outlet without changing it, enter
1
Pal will respond with one beep for OFF or
2 beeps for ON.
EXTENSION RING
The Extension Port can be accessed at any time after the command control/security code is entered by simply
pressing the
0
O P E R
key. This will cause the Pal to ring the Extension Port. If the device on the extension does not
answer, Pal will terminate the call. The number of rings Pal allows to the extension is user programmable (1-6
rings). Once the extension has been rung, no more power control codes are accepted.
CALL COMPLETION
Once Pal rings the Extension Port, it continues to monitor the call. When the call is completed, Pal will hang-up
the phone line and wait for the next call. Pal’s Power setting will remain in its last position.
Optionally, Pal can be set to automatically turn power off after a preset time (5 to 90 seconds). Use this setting to
automatically shut down equipment when the call is complete. A typical application would be to turn off a PC when
the modem call to that PC is finished. If the power is off when the call is terminated, this setting is ignored.
