Appendix G. Short-Haul Modems

With short-haul modems it is necessary to configure the base

station RF401’s “RS-232 Auto Power Down Enable” (in the

Advanced Setup \ Interface Parameters menu) to mode "0" which

will maintain the radio's RS-232 port always active. This results

in an additional constant 2 mA current drain by the RF401. If

you don’t do this, the base RF401’s RS-232 port will turn off 30

seconds after activity and the attached SRM-5A (which gets its

power from the port) will not receive any messages from the PC.

Refer to Appendix B for information about the Advanced Setup

menu.
