The DB25 Data Broadcast unit supports three leads on each port connector: Transmit Data (TXD), Receive Data (RXD), Signal Ground (SG).

The input to the composite "comp" port is regenerated and simultaneously sent out on the output lead of each of the eight slave ports, channels 1 thru 8.

The input into each of the slave ports is regenerated, 0Red together, and assembled to produce the output signal which is transmitted from the composite port. The signal grounds for all of the ports are tied together.

RTS, CTS, DTR, DSR, CD are also supported and looped back. The front panel indicators show the presence of primary power when the red PWR light is on. The state of the composite input signal is indicated by the COMP LED lighting whenever a "Space" is detected. The state of each slave port's input signal is indicated by the CH1-2 LED lighting whenever a "space" is detected.
