This data isolation and broadcast unit is a simple method of data distribution and amplification for up to eight RS232 ports. One master port is electrically buffered to provide data to the eight slave output ports. The unit is supplied in 2U table top case format (an optional rack mount kit is available) and measures 65mm in height. The data broadcast is ideal for use in applications in banks, control rooms and other areas where the same information is required to be displayed on a number of similarly interfaced serial monitors. It provides electrical isolation between separate channels and prevents the overload of one driving port by connection to multiple outputs.
The unit transmits data from the master to all slaves simultaneously. The reverse channel data lines from the slave ports are electrically gated without contention so that any slave port may transmit to the master port. Slave unit transmit selection must be done external to the unit. Up to 12 units can be daisy chained together by simply connecting the 9 pin connector on one unit to the 25 pin input connector on the next unit in the chain allowing up to 96 devices to be connected to a single port.
