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. 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-107N Photoelectric Isolation Interface Converter can provide credible connection for point to point, point to multi-point communication. The point to multi-point allows connecting 256 RS-422 or RS-485 interface devices 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.
RS-232 Booster Device :
The ATC-131 optically isolates and protects the transmit
and receive lines of your RS-232 port from ground loops and power surges up to
2500V RMS for one minute. The data stream is converted from an electrical pulse
to an optical beam, then back to an electrical pulse. Because there is no
electrical connection between the DTE and DCE sides of the isolator, the
ATC-131, unlike a surge suppressor, will not pass large sustained power surges
through to your equipment.
This isolator will protect both the transmit and receive lines at baud rates up to 57.6K without the need of an external power supply. Power is derived through the transmit and handshake lines. Special circuitry allows the ATC-131 to be powered regardless of the state of the handshake lines. At least one handshake line must be connected on each side of the isolator. Note that handshake line signals are not passed through the isolator.
