Description
- Model 485COSR is an economical converter that supports both 2-wire and 4-wire RS-485 communications. There is also provision for constant enable of the receiver during transmit for full duplex operation.
- Model 485TBLED is one of our most popular models with data traffic LEDs, RS-422/485 support, and either Automatic Send Data Control or software driver control.
- Model 485PTBR has a convenient terminal block that quickly unplugs from the converter for ease of wiring.
- Model 485CSP2 features both surge controlled and fused data lines on the RS-422/485 side plus all the features of model 485TBLED
