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.
