Isolated Converter By New Marketronika

Connector : DCE Side - DB 9 Female & DTE Side - DB 9 Male
Isolation : 2500V RMS Optical Isolation
Supply : Port Powered
Transmission Media : Twisted pair cable or shielded cable
Working Environment : 0degC-50degC,5%-95%RH

ATC-108
Photoelectric 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 . The built in
photoelectric isolator can offer 3500V isolation voltage and the rapid
Transient Voltage Suppressor (TVS) can effectively inhibit lightning and
ESD, provide 600W lightning strike and surge protection power on each
line and 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 7-bit plug-in
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-108 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-108
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
equipment with data transmission speed of 0-115.2KBPS. The 3 power supply
and data flow indication light can indicate malfunction. It supports
communication modes including RS-232C to RS-422, RS-232 to RS-485
conversion.
