(Your color code may vary
from the picture above)
1. Open the unit by removing the four (two per side) Phillips
head screws to remove the cover.
2. Push the end of the cable through the control wire feed
through on the rear of the unit.
3. Connections for the wire are made on the green header.
Loosen each terminal screw until it is near flush with the
top of the connector block.
4. Strip approximately 1/4" insulation from the wire end and
connect each wire to a terminal by sliding the wire completely into the wire connection hole.
Using a small flat blade screwdriver, tighten the associated screw until the wire is
firmly gripped in place as shown. (Your control wire color sequence may vary).
Take caution to ensure just the wire is clamped in place, not the wire's insulation which
would cause an open or intermittent connection. Do not over tighten the screw so much
that the wire is cut instead of being firmly gripped. Use a Ty-Wrap on the inside of the
unit to hold the cable from pulling outward as shown.
When connecting the control cable to the DX Engineering Pro-Stack Broadband Three Antenna
Phasing Relay Unit (DXE-PS-3B and DXE-PS-3BDIN), ensure your cable is wired the same way
at the other end to avoid un-necessary troubleshooting. Use the chart below to record which color
wire is connected to each terminal connection.
The green connector on the DX Engineering Pro-Stack Broadband Three Antenna Phasing Relay
Unit (DXE-PS-3B and DXE-PS-3BDIN) pulls straight off of the relay unit. Use a small
screwdriver to open each wire connection (same method as described
for the control console wire connections). Insert the stripped wire and
tighten. Do not allow insulation inside the connector which may
cause an open. When installing the green connector, push straight in
until fully seated.
