This document describes the features and characteristics of the ZFX series SCHE-C-739C and SCHE-738C products, as well as the communication interface specifications and serial communication command reference with PLC.
The document describes how to connect and operate the ZFX series sight sensor using various communication interfaces. It covers USB, RS‑232C/422, and Ethernet connections, command/response formats, and parameter settings.
Detailed interface specifications are given, including USB 2.0 full‑speed (12 Mbps) operation, RS‑232C/422 data rates up to 115200 bps, supported baud rates, data bits, parity, stop bits, and terminators. Ethernet communication follows TCP/IP peer‑to‑peer mode with cable lengths limited to 30 m for both point‑to‑point and multi‑drop configurations. This manual is written in Chinese.
