Description:
RS-422 and RS-485 Optical Isolator/Repeater - Connects point-to-point, RS-422 4-wire equipment to an RS-485 2-wire multidrop system.
- Optically isolates one piece of RS-485 equipment from the rest of an RS-485 system or one local group of RS-485 equipment from another.
- Can be used as a repeater to expand an RS-485 system beyond 32 nodes.
- Operates 2-wire half-duplex or 4-wire half- or full-duplex.
- Features 12 user-selectable data rates up to 460.8 kbps. RS-232<->RS-422/RS-485 Opto-Isolated Converters
- Converts half- or full-duplex RS-232 to half- or full-duplex RS-422 or RS-485.
- DIP switch enables the selection of data rates, 2- or 4-wire operation, echo, and termination. The RS-422 and RS-485 Optical Isolator/Repeater enables you to connect equipment meant for a point-to-point RS-422 4-wire interface to an RS-485 2-wire multidrop system. It can be used to optically isolate one piece of RS-485 equipment from the rest of an RS-485 system or one local group of RS-485 equipment from another, or it can be used as a repeater to expand an existing RS-485 system beyond the standard's 32-node limitation. All data lines as well as power and ground are isolated from one side of the unit to the other. The RS-422 and RS-485 Optical Isolator/Repeater uses terminal blocks on each side of the device. It supports Transmit Data A and B, Receive Data A and B, Protective Ground, and Signal Ground. The RS-422 and RS-485 Optical Isolator/ Repeater operates in either 2-wire half-duplex systems or in 4-wire half-duplex or full-duplex systems. By connecting one side of the unit as a 2-wire device and one side as a 4-wire device, equipment meant for a point-to-point RS-422 interface can be connected directly to an RS-485 2-wire multidrop system. You get speed with the RS-422 and RS-485 Optical Isolator/Repeater, too. It features 12 user-selectable data rates, from 300 bps up to 460.8 kbps. The RS-232<->RS-422/RS-485 Opto-Isolated Converters transform unbalanced half- or full-duplex RS-232 signals to balanced half- or full-duplex RS-422 or RS-485. An 8-position DIP switch enables you to select baud rate, 2- or 4-wire mode, echo, and termination. The transmitter is controlled by data or RTS.
