The Model ATC-101 is a non-power RS-232 to
RS-422 interface converter. The Model TBATC-101
has a DB9 Female connector for the RS-232
Interface and a 6 screw terminals connector or DB9
Male connector for the RS-422 differential input and
output interface.
MODEL TBATC-101 can convert the TD and RD
signals of RS-232 into balanced full-duplex RS-422
signals.
Interface is compatible with EIA/TIA RS-232C and RS-422 standard.
High efficiency serial port electricity stealing technology, need no external power supply, real three line (TD, RD, GND) mode communication.
Communication speed: 0-115.2KBPS.
Transmission distance: 0-1200 meter @24AWG.
Application fields
Point to point, point to multi-point communication.
Industrial distribution system, industrial control automation.
Road traffic control automation.
Closed circuit monitoring.
Security protection system.
Intelligent card, check on work attendance gate safety system.
