NV3128 RS-422A Machine-Control Routing Switch 2-10

2.2.4 CONFIGURING THE SERIAL INTERFACE (OBSOLETE)

2.2.4.1 JUMPER SETTINGS (OBSOLETE)

The serial data interface between the control system and the NV3128

can be either RS-422A or RS-232. For the newer Universal Control

module, the serial interface ports are set up using UniDiag. For the

older Command Interpreter, jumpers on the Command Interface

Module select parameters appropriate to the chosen protocol.

To select the protocol for data interchange with the obsolete Command

Interpreter, set jumpers on the module as shown in the following table.
