RS-232 Connection

The Serial (RS-232) connection on the Anthem processor should be connected with a straight through cable to the XP series processor serial adapter.

The baud rate of the Serial (RS-232) port can be set between 2400-115200. Default is set to 19200. Flow control on the AVM must be set to None.

Driver Notes

- Variable initialization for the zones (Main, Zone 2, and Zone 3) only happens the first time the zone is turned on. If the zone is already on, a power cycle of the zone may be required.

- Variable values for volume, balance, tone/eq adjustments, and channel levels vary from command to command. If a level is changed the value may initially be different from the front display reading of the Anthem processor (the processor display rounds the actual value), but will adjust shortly as a query command is subsequently sent updating the driver value to match the display.

- It is recommended that while using the driver, controlling the Anthem processor by any means other than the driver commands be kept to a minimum as the Anthem processor does not offer unsolicited feedback.

Note - This driver is NOT compatible with MRX Receivers.
