Converter assemblies 22300-759 and 22300-760 include two DB25M to DB9F modem cables.

These cables are appropriate for most Host connections. To determine if these cables are compat-

ible with your Host RS-232 communication port(s), contact your System Integrator.

The System Integrator will review wiring requirements for the Host RS-232 port(s) with the

converter-assembly cables. Should the cables not be compatible with the Host RS-232 port, the

cables may be altered, a modifying connector installed, or new cables may be purchased at a local

cable supplier.

Individual converter part numbers 61-825-0966-4 and 61-825-1032-4 do not include a serial cable

for connection to a Host. It is the responsibility of the System Integrator to obtain the correct serial

cable based on the Host RS-232 port connector and Limitorque converter RS-232 port connector.

5.1.1 RS-232/RS-485 Control Line Steered Converter

(P/N 61-825-0966-4)

This is the standard converter offered by Flowserve for use with Limitorque networks. This

converter provides isolation, surge protection, data rate, and distance capability that is equivalent

to the self-steered converter. This converter uses either Host RS-232 port RTS (Request To Send)

or DTR (Data Terminal Ready) (DIP switch selectable) signals to steer the RS-485 data direction.

This converter also provides a directional steering output for Limitorque’s A/B Switch (P/N EEC-

90001840).

In the converter, the RS-232 data is converted to TTL signals. The signals drive indicating LEDs and

inputs of optical couplers that drive the RS-485 converter circuit. The optical couplers isolate the

Host hardware from the RS-485 Network. The RS-485 circuit is bi-directional and must be steered
