Section 2 Installation & Setup
There are 2 versions of Control Cabinet for the SigmaCD transmitter.
a.
In the newer style cabinet
the exciter serial
connections are already extended to the Cus-
tomer I/O panel in the top rear area of the
Control Cabinet. Connect the “Y” splitter
cable to the Exciter A and Exciter B connec-
tions (both are male D connectors) on the
Customer I/O Panel and then connect the
eCDi™ serial cable (female to male) to the
“Y” cable as shown in Figure 2-5 (at right).
b.
In older style cabinets
, the exciter serial port
extension cables connect to the System I/O
Board behind the customer I/O Panel, see Fig-
ure 2-6A. In this case, disconnect the 2 serial
cables, labeled 76 and 77 (both are male D
connectors), from the System I/O Board and
connect the “Y” cable directly to the end of
the serial cables. Two (2) standoff kits are pro-
vided to allow the exciter cables and the Y
adaptor to be connected together. Then con-
nect the eCDi™ serial cable (female to male)
to the “Y” connector. The completed assem-
bly is shown in Figure 2-6B.
