TxLD WIRING INSTRUCTIONS.
Twin Twisted Pair connection between the TxLD mk2 units.
TxLD(B) Base Unit End
TxLD(K) Keyboard End
Matrix End
After connecting the twin twisted pair cable to the green IMO connector mount the TxLD to a wall if required
and connect to the Tx1000 base unit keypad 2 connector with the serial lead supplied (SA-PL61-1). The
TxLD does not require a power supply, it obtains its supply from the Tx1000 Base Unit.
Keyboard End
Before mounting the TxLD, connect the slave Keyboard power supply to the power entry on the TXLD and
connect the slave keyboard cable to the DB9 connector. The keyboard will not need a separate power
supply as it is now powered through the serial lead.
The video connection will need to be made from the monitor output on the TX1000 Base Unit through the
Slave Keyboard (for on-screen text) and on to a monitor.
