6.2 Demo Cable
This cable allows two DVST units to be connected back to back without the need for
connection to MODEMs or Terminal Adapters.
Tech Note:
This is a synchronous balanced transmission. Transmit and receive lines therefore
cross yet maintain polarity. The flying lead is used to source a clocking signal from the
MODEM port.
