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.
Product features:
DB9-S/P space saving connector.
Interface is compatible with EIA/TIA RS-232C and RS-422 standard.
