Expansion Bus; Connecting The Exp Ports - Extron electronics XMP 240 C AT User Manual

Expansion Bus

With the Extron Expansion (EXP) port, two EXP-enabled devices can be connected for
bidirectional streaming of up to 16 channels of audio. EXP inputs and outputs contain DSP

Connecting the EXP Ports

When connecting an XMP 240 C AT to another EXP-enabled device for EXP
communication, the XMP 240 C AT is always set as the primary unit. The primary unit
serves as the master clock for all EXP audio communication. The other unit must be set as
a secondary unit in order for a connection to be established.
The following procedure describes how to set up a XMP 240 C AT model with another
EXP-enabled non-AT device for EXP communication.
NOTE: Two XMP 240 devices cannot be connected via the EXP port because the

NOTES:
• The XMP 240 C AT cannot be configured as a secondary unit. This means the
DMP 128 Plus non-AT must be configured as a secondary unit.
•
If both devices are configured as primary, an EXP connection cannot be
established.
Use a CAT 6 cable (such as the 1 foot cable included with the XMP 240 C AT) to
connect the two rear panel EXP ports.
When the connection is established, the front panel EXP LED on the primary unit lights
steadily and the EXP LED on the secondary unit blinks rapidly.
NOTE: The DTP CrossPoint EXP LED is located on the rear panel next to the EXP
port.
