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 header "H1". Loosen each terminal screw until it is near
flush with the top of the connector block as shown below.
4. Strip approximately 1/4" insulation from the 9 conductor wire ends
as shown to the right.
5. 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 below.
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 the included Tye-Wrap on the inside of the unit to hold the cable from pulling outward as
shown above.

Shielded cable is recommended. The drain wire (bare wire) is used as the signal ground return.
Both of the "G" connections are internally tied together. When connecting the cable to the
DXE-EC-8
,
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 selected position will
supply the DC voltage that is connected to the
DXE-EC-8
.

Control lines (usually BCD ) can normally use good quality CAT5e cable (4 twisted pairs of 24
AWG wire) for runs up to 1000 feet. Typical DX Engineering BCD control lines requirements are
+12 VDC at 25 milliamps. Depending on the number of control lines needed (usually 3 or 4) you
can double up the twisted pairs of CAT5e cable, or use control wire that is at least 22 AWG,
allowing runs up to 1500 feet. If you use a cable with more conductors, it is a good idea to tie the
