On the DSI 2008 front panel, set the CHAN SEL switches as follows:
Balanced Configuration: set the CHAN SEL switches to the BAL position.
Unbalanced Configuration 1: set the CHAN SEL switches to position 1.
Unbalanced Configuration 2: set the CHAN SEL switches to position 2.
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 CS, and Zeus
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 11.
ADAM GPI Connector: XCP-ADAM-MC, J11
ADAM CS GPI Connector: J903
Zeus GPI Connector: J27
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 11 and Table 2 on page 12).
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 13.
Typical GPI connections are shown in Figure 5 on page 11. 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.
