2. The unit is set at the factory for synchronous
transmission at 9600 bps. The ASYNC/SYNC
jumper selects transmission mode. The 9-position
rotary switch selects the baud rate. Set the pointer
of the switch to the number that corresponds to
the baud rate as shown on the inside of the
multiplexor.
NOTE
Asynchronous operation cannot be faster than 9600 bps.
3. Connect the 4-wire cable to the 4-screw terminal
block.
NOTE
The transmit pair at the local site must be connected to
the receive pair at the remote site.
4. Align the top half of the cover with the bottom
half and press the two halves together to close the
unit.
5. Connect the RS-232C connectors of the Miniature
Local Multiplexor to the RS-232C devices.
