NOTE: If System A or System B will not be used, set the 2W CHAN SEL switch to the off position and attach a
dummy load to the TW XLR connector.
4-Wire Call Signal Connections
NOTE: These connections require the call signal option.
Call Signal Connection for ADAM, ADAM-M, ADAM CS, Zeus and Zeus III
You can use the General Purpose Interface (GPI) connector to interface call signals. The pin-out of the connector is the same
for all of these intercom systems Table 1 on page 13.
ADAM/ADAM-M GPI Connector: XCP-ADAM-MC, J11
ADAM CS GPI Connector: J903
Zeus GPI Connector: J27
Zeus III GPI Connector: GPI
If your intercom system is equipped with a UIO-256 (Universal Input/Output) Frame, you can also use that for connections
(Table 1 on page 13 and Table 2 on page 14).
As an alternative to using the GPI, you can use external components to send and receive call signals as described in “Call
Signal Connections for other 4-wire Communications Systems” on page 15.
Typical GPI connections are shown in Figure 4 on page 12. The example uses GPI outputs #1 and #2 and GPI Input #1. You
may substitute other GPI Input and Outputs.
IMPORTANT: AZedit version 1.06 or higher includes a feature which allows you to invert the action of the GPI
outputs. By default, these output are set to duplicate the action of the RTS FR9528 Relay Frame
accessory. This is the correct setting for use with the DSI 2008. To check the AZedit setting, select
Intercom Configuration in the Options menu. Click on the Options tab, then verify that Configure
onboard GPI outputs in FR9528 mode is selected.
