ATC-105 Isolation Interface Converter is
compatible with RS-232C, RS-422, RS-485 standards and
capable of converting single end RS-232 signal into RS-422
or RS-485 signal of balanced signal. The built in
photoelectric isolator can offer 3500V isolation voltage
and the rapid Transient Voltage Suppressor (TVS) can
effectively inhibit lightning and ESD, prevent lightning
strike and common code interference. Connect PC, IPC,
or portable computer via a DB9 female connector at RS-
232 interface, and connect RS-422, RS-485 end via
convenient 4-bit terminal. The RS-485 supports dual-line
half duplex, namely, the only two lines of RS-485 shall both
send and receive data. Handshake signal (e.g. RTS, Request
To Send) usually controls the data direction. The inner
circuit of ATC-105 Photoelectric Isolation Interface
Converter can detect data direction and switch to control
it automatically, conveniently to form a RS-485 network
without any shake hand signal. This kind of RS-485 control
is fully transparent and need no software amendment for
the former working modes basing on RS-232.
ATC-105 Photoelectric Isolation Interface Converter can provide credible connection for point to point, point to multi-point communication. The point to multi-point allows connecting 32 RS-422 or RS-485 interface devices with data transmission speed of 0- 115.2KBPS. The dual color data flow indication light can indicate malfunction. It supports communication modes including RS-232C to RS-422, RS-232 to RS- 485 conversion. Categories related
