On the other end of the link, attach the other computer used for RS-485 testing to the same pins of
connector J3 of the Mini4 RS-485 channel. This will allow the two RS-485 test computers to talk to
each other through the Mini4 boards. Both RX and TX LEDs on both boards should be lit and/or
flickering in response to the data traffic.
If the RS-485 data channel is not operating correctly, first check the RS-485 wiring then the jumpers
on both Mini4 boards. If the wiring and jumpers appear correct, then replace first the Video Input
board with a spare and check the RS-485 again. If the problem is still there, return the original Video
Input board, replace the Video Output board with a spare and check the RS-485 again.
If any of the LEDs are not operating correctly check one of the other channels. If the LEDs operate
on that channel, replace the Mini4 board with a spare board or use the working channels only.
If one or more RS-422 data channel is out or has errors:
Run RS-422 data into appropriate pins of connector J3. The RS-422 data can be input into either the
remote vehicle or surface Mini4 board.
On the other end of the link, short the TX3+ pin to the RX3+ pin and the TX3- to RX3- pins of
connector J3 of the Mini4 RS-422 channel being tested. This will allow the two Mini4 boards to talk
to each other in loop back. Both RX and TX LEDs on both boards should be lit and/or flickering in
response to the data traffic.
If the RS-422 data channel is not operating correctly, first check the RS-422 wiring then the
jumpers on both Mini4 boards. If the wiring and jumpers appear correct, then replace first the
Video Input board with a spare and check the RS-422 again.
If the problem is still there, return the original Video Input board, replace the Video Output board
with a spare and check the RS-422 again. If any of the LEDs are not operating correctly check one
of the other channels. If the LEDs operate on that channel, replace the Mini4 board with a spare
board.

Stack Mini4 System Installation Checkout Procedure
For this PC/104 stack Mini4 System installation checkout procedure, it is assumed that the Mini4 System
is composed of a Video Input board mounted in the vehicle and a Video Output board on the surface.
+5VDC power for the Mini Mux boards is supplied by the user’s DC power supply. Power to be
connected to the green 2-pin Phoenix connectors located on the right side of the board (J6 on the Video
Input, J5 on the Video Output). Note that these boards DO NOT have PC/104 connectors.
1.
At the vehicle, mount the Mini4 Video Input board at a convenient space within the existing PC/104
stack. The board does not use the PC/104 bus. +5VDC power must be applied to the green 2-pin
Phoenix connector J6.
2.
Repeat all of the previous steps to install the Mini4 Video Output board at the surface.
3.
Follow steps 6 through 10 from the previous section.
