Product Details
The AC24AT and AC422AT cards provide an asynchronous RS-422/485 communications port for the ISA bus. The adapter cards are seen by the computer as standard COM ports.
These cards are transient protected, feature bi-directional handshake lines for RTS and CTS, and can drive up to 32 devices on a multi-drop network. They are designed for communicating to Optomux brain boards in RS-422/485 4-wire mode and support baud rates up to 115.2 kbaud.
In addition, the AC24AT card provides 4,000 volts of isolation between the ISA bus and the communications link. The AC24AT card can also be set up for RS-485 2-wire mode; however, special software drivers are required to take advantage of this. These special software drivers are not provided by Opto 22. For 2-wire RS-485 solutions, use Opto 22's AC37 (ISA bus adapter) or AC7A (stand-aloneRS-232 to RS-422/485 converter)
