This document describes the features and characteristics of the ODR-C06 optical isolation converter, including automatic direction flow control, automatic baud rate switching, 3000VDC power supply and signal isolation protection.
The ODR-C06 provides bidirectional conversion of RS232 to RS422 or RS485, featuring automatic data‑format detection and baud‑rate switching from 1.2 Kbps to 115.2 Kbps. Optical isolation of 3000 VDC protects connected equipment from ground loops and voltage spikes.
Installation is done via a DIN‑rail, and the unit accepts a wide power range (DC +10 V to +30 V) through either an external DC jack or screw‑terminal input (only one source at a time). LED indicators show power, TX and RX status, and the device supports standard D‑Sub 9‑pin female connectors for host connections. This manual is written in Chinese.
