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.
