3-3-2 Purpose
A Serial Communications Option Board is used to connect the CPU unit to general-purpose compo-
nents with a serial interface in order to perform data I/O processing. The general-purpose components
with a serial interface includes a bar code reader, Temperature Controller and PT.
An RS-232C and RS422A/485 ports are supported, and up to two ports can be added to the CPU Unit.
The supported communication protocols are the host link, Modbus-RTU master, and no-protocol.
Refer to the NX-series NX1P2 CPU Unit Built-in I/O and Option Board User’s Manual (Cat. No. W579)
for details on how to use the Option Boards.
