Milestone's "RS232C to RS485/RS422 Converters" are designed for high speed data transmission between computer system and or peripherals over long distance under noisy conditions. It provides opto isolation (2500 V) against erroneous glitches, spike suppression and short circuit protection on each transmission line. They provide dual line differential per signal. Various models are available. All the models support upto a distance of 1.5 kms. All models have LED indication for Tx, Rx and PWR line. |
