To unlock the front panel
1. Attempt to adjust a parameter. The GT1524 prompts you for the passcode.
2. Begin entering the passcode. Once you have correctly entered the fifth
character, the front panel unlocks. (The default passcode for all units is Up,
Up, Down, Down, Enter.)
Set Passcode
Once you have unlocked the GT1524, you can change the passcode. Before the
GT1524 allows passcode changes, the new passcode must be entered, then re-entered
to validate it. The passcode must be five front panel buttons (in any combination or
multiple).
RS-232
Two RS-232 parameters can be adjusted through the front panel LCD: baud rate and
flow control. If data is lost during serial access through the RS-232 port, a serial
overrun error will occur. This is indicated on the LCD display. This parameter sets
the GT1524’s RS-232 port communication rate at 9,600 (default), 19,200, or
38,400 baud (bps).
Baud. To set the baud rate, scroll through the settings to select the desired baud
rate, then press Enter.
Flow Control. The flow control parameter allows activation and deactivation of
hardware flow control. The two options are On and Off (default). To activate the flow
control, scroll to On and press Enter. To deactivate it, scroll to Off and press Enter.
Telco
Auto-Answer On/Off. This parameter sets the telephone interface to automatically
answer an incoming call (Auto-Answer On), or allow the call to be handled manually
(Auto-Answer Off).
Auto-Disconnect. The interface can also be set to disconnect upon Loop Drop, Call
Progress, Loop Drop + CP, or to disconnect manually (Auto-Disconnect Off).
