1. Introduction The industrial converter is designed to convert RS-232 signals to opti- cally isolated, balanced, full or half-duplex RS-422 or RS-485 signals at baud rate up to 115.2Kbps. It features RTS control design, which allows TM software to control RS-485 transmission. With smart ADC (Auto Data Control) design, the converter can uses send data signal to control RS- 485 transmission automatically so no software control is required in RS- 485 mode. The Din-rail mountable design makes it id

2.3 DIN-Rail Mounting In the product package, a DIN-rail bracket is installed on the device for mounting the converter in a industrial DIN-rail enclosure. The steps to mount the device onto a DIN rail are: 1. Install the mounting bracket onto the device unit as shown below: 2. Attach bracket to the lower edge of the DIN rail and push the unit upward a little bit until the bracket can clamp on the upper edge of the DIN rail. 3. Clamp the unit to the DIN rail and make sure it is mounted securely.
