Flow Control
This 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.
Modem Mode
This parameter controls whether the AP800 is set to communicate by a modem
through its RS-232 port. Upon activating modem mode or when power is turned on
while modem mode is active, the AP800 sends an init string to the modem to
initialize it. (The init string can only be set through the RS-232 port. See Appendix
F, page 49 for information on the the MINIT serial command.) The default setting is
off. To activate modem mode, scroll to the on setting and press Enter. To deactivate
modem mode again, scroll to off and press Enter.
Clear Password
This parameter clears the RS-232 password for modem access. This password is set
with the RS-232 command MPASS (see page 50 or refer to AP-Ware). The Clear
Password function is helpful if the password is forgotten and needs to be reset.
However, the password cannot be set via the front-panel LCD. It can be set with the
RS-232 port or AP-Ware. This password is not to be confused with the front panel
passcode, which performs a completely different security function.
Serial Overrun Errors
If data is lost during serial access via the RS-232 port, a serial overrun error will
occur. This is indicated by flashing microphone LEDs. If the error is caused by
incoming data, LEDs “3” and “8” will flash green. If the error is caused by
outgoing data, LEDs “3” and “7” will flash green. Call ClearOne Technical Support
for help correcting this error.
Timeout
The AP800 has one additional system mode called Timeout. This parameter can be
adjusted via the RS-232 port using the TOUT command (see page 56) or software.
Timeout controls the delay time (in minutes) before the AP800 LCD panel will
automatically switch back to the title screen and default meter. The range is zero to
15 minutes. Default is 10 minutes; zero disables this mode.
The init string can be set
only with the MINIT
serial command (see page
49) or AP-Ware software. It cannot
be set through the front panel LCD.
Disabling the timeout will
allow the AP800 to
remain in the same
position in the LCD menu until the
LCD menu is manipulated again.
