RS-232C to RS-485 Conversion (continued)
Use the following wiring diagrams to connect DirectLOGIC RS-232C PLCs to a
DURA
PULSE Series AC drive with an FA-ISOCON network adapter module:
A cable that will connect the D0-DCM or DL250(-1) to the FA-ISOCON can be
constructed using the FA-15HD adapter and the D0-CBL cable. A cable can also be
constructed using the FA-15HD adapter and RJ12-6P6C cable from the FA-CABKIT.

D0-DCM/DL250(-1): RS-232C to RS-485 Connection Wiring
Cable D0-DSCBL (12ft; 3.7m) is available for connecting the DL05 to the FA-ISOCON.
For a single run to only one AC Drive
, cable GS-ISOCON-CBL-2 (2m; 6.6ft) is available
for directly connecting the FA-ISOCON to the GS3 Com Port.
