Option Board
Specifications of Serial Communications Option Board
*1. Projecting parts such as a terminal block is not included. When the Option Board is mounted to the CPU Unit, it protrudes through the CPU
Unit surface. Refer to the NX-series NX1P2 CPU Unit Hardware User’s Manual (Cat. No. W578) for details.
*2. The terminals are isolated from the internal circuits of the CPU Unit.

Note: 1. As the Option Board does not have a 5 V power supply terminal, it cannot be connected to external
converters such as an CJ1W-CIF11 and NT-AL001, or an NV3W-M20L Programmable Terminal.
2. The terminal block is not removable.
