2.4.3.3 Exciter Connections
HX-1V Analog Exciters
The eCDi™ does not connect to the HX-1V analog exciters.
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. Since the eCDi™ unit will be
mounted external to the control cabinet in most installations the recommended
connection is as follows:
a.
Connect the provided, 10ft, 9 pin serial cables labeled RS232 Diag EXC A and
RS232 Diag EXC B to the RS232 ports on the back of each exciter and route the
cables with the exciter wiring harness. See Figure 2-11 for connection drawing.
