The following connection points can be made through the “D”
connector or, in OEM applications, made through the circuit board
solder pad connections.
The display pad connections are shown for applications requiring
remote mounting of the digital display. The letters appear on the
display circuit board and are shown in Figure 2-3.

NOTE: the numbers on the connector plug may not agree with the
numbering system as it appears on our Figure 2-2 (on previous
page). It is important to make sure that the proper wires are in the
proper location rather than the proper number. Most connectors
utilize a standard numbering scheme but there are a few that do
not.
The remote display connects through the 9-pin “D” connector only.
The pads A-D in the top right of the main circuit board are for
integral display mounting only.
*1 Power supply voltage must be specified at time of order. Operating a 12 VDC meter at
24 VDC will cause damage. Running a 24 VDC meter at 12 VDC will result in faulty
operation.
*2 Do not DC power at the “D” connector while using a power supply at the DC
power jack. Both supplies may be damaged.
