Incorrect wiring - TX+ (terminal 1) was connected to RX- (receiver).



Using the KBD300A in Direct Mode is a single keyboard installation.

To connect the keyboard:

  1. If the dip switches on the keyboard have not been set already, set 5, 6, 7 ON (down).
  2. Determine the location for the keyboard. The keyboard must be located within 25 feet (7.6 m) of where you will install the wall block. The wall block must be within 6 feet (1.8 m) of the nearest electrical outlet to accommodate the transformer.
  3. Remove the cover from the wall block. Wire the connections between the wall block and the receiver/driver.
  • Connect TX+ (terminal 1) on the wall block to RX+ on the receiver.
  • Connect TX- (terminal 2) on the wall block to RX- on the receiver.
  • Connect the transformer to terminals 3 and 4.

      4.   Replace the cover on the wall block. Secure the wall block to a suitable surface with the double sided sticky pad that is supplied.
      5.   Plug the transformer into a power outlet.
      6.   Connect the 25-foot (7.6 m) cable that is supplied with the keyboard. Plug one end into the wall block and other end to keyboard receptacle.
