UT-2212/3212 series RS-232 long drive or a long-term transceiver or long distance repeater, it can extend the communication distance of two asynchronous communication RS-232 devices to a maximum of 1.2 km. As a result of the lightning protection technology, the complete protection of the interference of both ends of the RS-232 devices surge damage, and significantly improve the reliability and stability of the communication system, at the same time due to changes in the original RS-232 interface single-ended transmission mode, use the twisted pair transmission, greatly improving the communication distance. Dedicated its own line asynchronous RS-232 point-to-point through the field, can be used the UT-2212/3212 to meet the demand of the interface to protect or extend the distance. UT-2212/3212 4-wire, 6-wire products. UT-3212 4-wire products can send a pair of data signal, RTS, CTS flow control. UT-2212 6-line products can send a pair of data signal also can send two pairs of control signals, DTR, DSR, RTS, CTS flow control signals. 
UT-2212/3212 compact, and less demanding on the wire, the best available the general network cable or 8-core twisted pair shielded cable wire. The devices can be plugged directly into the RS-232 interface, very easy to use. 
UT-2212/3212 series products have been widely used in point-to-point RS-232 communications, multi-user terminal and the host connection, RS-232 remote control systems, PABX billing terminal, a satellite receiver.
