Cabling
Base Station RS422 10 Metre Cabling
The MetPak Base Station comes with an integral 10 Metre, Belden 8104 cable
fitted to the hub box connector J4, (RS422 interface).
It is terminated in Clipper connector solder contacts for installing into a WindSonic
Option 2 or WindMaster/WindMaster Pro Connector (connectors supplied with the
Wind Sensor).
If used with a WindObserver 70 or WindSonic M the contact pins will need to
be cut off and wire stripped/soldered for termination into the Heater Power
Interface Box.
Details on fitting the connector pins on the 10 Metre cable into the WindSonic
option 2 or WindMaster/WindMaster Pro connector are as follows:-
If shortening the 10 Metre cable to a required length, strip and prepare as follows:-
1. Trim back the screened cable outer PVC sheath to 52mm.
2. Trim back the braid and drain wire to 20mm from the outer sheath.
3. Separate braid and drain wire from the foil and cores. Twist braid and drain
wires together.
4. Trim the twisted braid and drain wire to 15mm from the outer sheath and
tin ends 5mm.
5. Cut the foil and White/Green wire back to within 5mm of the outer sheath.
6. Strip and tin one end of the White/Green wire removed to 5mm.
7. Locate White/Green wire to twisted braid and drain wire and solder.
8. Insulate the White/Green wire joint.
9. Strip back the connection wires by 4mm and tin solder.
10. Solder the contact pins supplied with the connector to the wires.
11. Note that the sensor connector supplies the correct strain relief for cables
with an outside diameter of 6-12mm.
Route the cable through the connector parts as in direction shown below
(WindSonic connector shown, the WindMaster Connector is similar).
