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.
