Description :
ATC - 155, RS - 232 photoelectric isolation line drives or line transceiver or line repeater insulation. It can be in optical isolation and make two equipment for asynchronous communication of RS - 232 communication distance is increased to 12 km at the same time. Due to adopt photoelectric isolated technology, completely isolated RS - 232 devices on both ends of the electric and ground wire loop, so as to protect communications equipment from the power supply ground loop interference and surge damage, significantly improve the stability and reliability of communication system. Due to the changed the RS - 232 interface way of single side transmission, using the double balance transfer, greatly increase the communication distance. In the use of dedicated line of asynchronous point-to-point RS - 232 field, ATC - 155 can be used to meet the needs of interface protection or extended distance. ATC - 155 volume small, the wire has no special requirement, don't need an external power supply, can be directly inserted to the device of the RS - 232 interface, use very convenient.
