Description
When installed, the recorder output board is located below the display board and extends
out from under it so the terminal strips are accessible for wiring. When it is installed along
with a heavy duty relay board, the heavy duty relay board is installed below the display
board and the recorder output board is below the heavy duty relay board (see Figure 12).
The recorder output board connects to the main board with two cables. One 34 position
ribbon cable runs from the connector labelled J2 in the lower left of the recorder output
board to the analog expansion connector on the left side of the main board just above the
transmitter terminal strips. The other cable has a three position connector on each end,
but one position is unused. This two wire cable runs from J1 in the upper right of the
