The rear serial port is used for integrating the AudioReQuest with a control system. Connection to the rear

serial port requires a FemaleÆFemale NULL MODEM serial cable. The front serial port(if equipped) is

used ONLY for configuring certain settings on the AudioReQuest, such as the IP Address. You CANNOT

use the front serial port to control the ARQ.

The default baud rate depends on the model of AudioReQuest unit. On newer AudioReQuest units, the

baud rate is configurable in the webserver (SettingsÆHardwareÆControl Port Baud Rate). The table

below shows the default baud rates by model.
