Overview
Applications
- Serial printer communication: Supports serial printers through the RS 422 / 485 point-to-point connection.
Key Features
- RS 422 / 485 interface: One isolated RS 422 / 485 (X.27) interface with a transmission rate from 0.3 kbit/s to 115.2 kbit/s.
- Supply and power loss: Rated supply: 24 V DC. Input current: 100 mA max. from supply voltage L+ and 70 mA max. from the backplane bus 5 V DC. Power loss: 1.6 W typ., 2.4 W max.
- Integrated protocol drivers: Supports 3964 (R) and RK 512, not with RS 485, plus ASCII. Each listed protocol has a maximum telegram length of 4 096 byte.
- Connection and cable length: Point-to-point connection supports serial printers and a cable length of 1 200 m max. The connector is a 15-pin sub D socket.
- Diagnostics and configuration: Diagnostics LEDs indicate Receive RxD, Transmit TxD, and Group error SF (red). A configuration package on CD is included.
- Product lifecycle: Product cancellation.
