Overview
Xicom digitally controlled devices monitor their serial ports for
incoming messages and respond to messages as soon as they
are verified. Response time varies, typically ranging between 20
and 100 milliseconds. Although devices will respond to
messages with invalid parameters, they ignore messages with
invalid address bytes or check bytes.

for basic configuration.
Note
In this chapter, the term
analog
refers to devices without a serial
interface. The term
digital
refers to devices with a serial interface (RS-
232/RS-485/Ethernet).
Communication
Digital HPAs
Both rack-mounted and outdoor digital HPAs have a built-in
microprocessor for handling serial communications. With the
exception of the Prime Power Switch, all operation of digital
HPAs can be completely controlled via the serial interface (RS-
232/RS-485/Ethernet).
Analog HPAs
With a Xicom digital controller, analog HPAs can be completely
controlled using a serial interface. Although Xicom’s analog
HPAs can also be controlled via an analog controller, a digital
controller is needed to emulate the serial protocol of a digital
amplifier.
Compatability
Typically, two serial hardware interfaces (RS-232, RS-422/485)
are available for the control link. In some cases an ethernet
interface is also provided.
