RDU™

Remote Data Unit

THE PRODUCT
The Remote Data Unit (RDU) is a high density serial port expander module that has 12 DB25 serial ports and 1 ethernet port. The RDU is available for use with the BANDIT Plus and the VSR-1200 product. Each serial port on this module can handle both sync/ async legacy data protocols that are currently supported by Encore Networks’ ELIOS operating system.

The RDU is 1U high and 19” rack-mountable. Because it is a peripheral unit, the RDU can sit in any location. It is convenient to install the RDU in an equipment rack above or below the BANDIT Plus or the VSR-1200. The connectivity between the RDU module and the BANDIT-Plus or the VSR-1200 takes place over a 10baseT Ethernet port

The figures below show the front and the rear of the RDU. (Note that the RDU has its own AC power connection. The front of the RDU has 12 LEDs, one for each serial port. Please refer to Encore Networks product manuals for description of the LED states for the RDU’s serial ports.

Each serial port on the RDU is a DB25 female connector, physical DCE RS-232. A DB25-to- DB25 crossover conversion cable is to be used if a physical DTE interface is required. The front of the RDU has 12 LEDs, one for each serial port. Table 2-10 describes the LED states for the RDU’s serial ports.
