RS422/232 Converter
RS485/232 Converter
ATC-101 Port Powered RS-232 to RS-422 interface converter
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 fullduplex RS-422 signals.
ATC-106 Port Powered RS-232 to RS-485 interface converter (4-bit terminal)
ATC-106 (ATC-101) can covert the data from RS -232C to half duplex RS-485(RS-422)
signal. It don't need additional power supply and can get the power directly from PC side. By
it's "Automatic Send Data Line Control" function, you don't need to use RTS, just plug it and
no need to install any hardware or software and work well under RS-485(RS-422)
