DGH DC-Powered RS-232/RS-485 Converters  RS-485 Repeaters
A2000
The DGH A2000 series converters convert RS-232 communications signal levels to the correct electrical signals required by RS-485. RS-485 is recommended when many DGH modules, or other addressable devices, must be connected to a host computer over long distances. The A2000 converters allow communications bus lengths up to 4,000 feet and baud rates up to 115.2K baud using one twisted pair of wires. Therefore, host software written for half-duplex RS-232 may be used without modification. The RS-485 bus control is completely transparent to the user. Use the CA-2 cable to connect to a host computer 9 pin serial port.	A2000 Top = Rear View Bottom = Front View CA-2
A2400
The A2400 converter performs an RS-232 to RS-485 conversion and provides handshaking signals for those applications where data flow must be synchronized to a communications device. Devices such as radio or leased-line modems sometimes require that handshaking signals be asserted before data can be transmitted thru them.  The A2400 provides an active Request-to-Send (RTS) signal and contains optional Clear-to-Send (CTS) support.
