20 Installation ~ LCD Programming

✍ 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.

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.
