Section 2 Installation & Setup
eCDi ™
2.4.2.4
Exciter Connections
APEX Exciters
To connect the eCDi™ to an APEX™ exciter requires a standard ethernet cable (not
cross-over) with RJ-45 connectors on each end. Two (2) 50ft ethernet cables labeled
EX1 and EX2 have been provided. Connect the exciter(s) to the RJ-45 ports on the back
of the eCDi™ labeled EX1 and EX2 in Figure 2-2.
IMPORTANT:
The IP address and Subnet mask must also be set up in the APEX exciter. See
"2.5 APEX Exciter Setup" on page 2-22
.
NOTE:
When routing the ethernet cable to the back of the exciter, make sure to follow the
cable supports and wiring harness to allow the exciters to be pulled completely
out the front to the extent of the rack slides. Cable ties have been provided to
secure the cables to prevent damage when the exciter is pulled out for service.
CD-1A Exciters
CD-1A exciters connect to the eCDi™ via serial port. Connect the provided 50ft serial
cable labeled “EXCITER” to the serial port labeled “EXCITER” on the eCDi™ . Route
the cable into the back of the GUI control cabinet in the transmitter. This cable connects
to the provided Y adaptor in the transmitter control cabinet. The Y adaptor allows 2
exciters to be connected to the eCDi™ on the same serial port. Connection of the Y
adaptor cable depends on the age of the control cabinet. Both types of cabinet are
covered on the next page.
NOTE:
The exciters can both be connected to the same serial cable because they only have
access to the serial port if they are the active or ON-AIR exciter in the transmitter.
