The DGH A2000 is a bi-directional RS232/RS485 converter. RS485 is recommended when many DGH modules, or other addressable devices, must be connected to a host computer over long distances. The A2000 RS232/RS485 converters allow communications bus lengths up to 4,000 feet and baud rates up to 115.2K baud using one twisted pair of wires.

The A2000 may also be used as an RS485 repeater. RS485 repeaters re-amplify the RS485 signal when transmitting >4000 feet. They also allow more than 32 devices to be connected to the RS485 bus.

The A2000 is DC powered using an unregulated or regulated +10 to 30Vdc power supply.

Use the CA-2 cable to connect to a host computer 9 pin serial port.

The A2400 is an RS232/RS485 converter designed to interface all DGH RS485 products to radio and leased telephone line modems.

The A2400 is a bi-directional RS232/RS485 converter that provides RTS and CTS support. RTS (Request-to-Send) and CTS (Clear-to-Send) are handshaking signals for  where data flow must be synchronized to a communications device, such as a radio or leased line modem.

The A2000 is DC powered using an unregulated or regulated +10 to 30Vdc power supply.

The A2400 series module can be mounted on a DIN-Rail using the MK-1 mounting kit.

  DIN-191 Module!

The DIN-191 converter module converts RS232 signal levels to the correct electrical signals required by RS485.

The DIN-192 module operates as an RS-485 repeater. RS485 repeaters are required to extend communications bus lengths or allow more than 32 devices to be connected to a communications bus.
