T107 Weather Station
Install the short-haul modems as shown in FIGURE 2-25 and FIGURE 2-26.
1. Mount the Rad / SC932C mounting bracket into the ET Enclosure with the
three pre-threaded screws provided.
2. Connect the Rad Modem and SC932C. Strap them into the mounting
bracket under the Velcro strap.
3. Connect the SC932C 9-pin port to the internal ET Enclosure CS I/O port
with the pn 10588 Ribbon Cable supplied with the ET Enclosure (see
FIGURE 2-25).
4. Wire the Rad Modem to the ET Enclosure with the 12-inch patch cable.
Match wire labels to wiring panel labels on both the ET Enclosure and the
Rad Modem (+XMT to +XMT, etc.). A small screwdriver is provided
with the ET Enclosure to access the Rad Modem connections. Use the
screwdriver to press down on the lever arm.
Pressing too hard on the lever arm can cause it to
break!
2.5.3.2 External Installation
The following short-haul kit components (see FIGURE 2-23) are used to make
the external connections:
At the ET Enclosure:
(1) 20 foot 4-Wire Patch Cable
(2) 2 Direct Burial Splice Kits
(1) Length of User Supplied Wire (Supplier: Anixter, pn F-02P22BPN,
Phone 847-677-2600)
At the PC:
(1) Rad Modem
(1) 5 foot 4-wire Patch Cable
(1) 10 foot 14 AWG Ground Wire
(1) Surge Protector and Case
(1) 9-25 Pin RS-232 Serial Cable
1) Connect the 20-foot patch cable to the connector marked COM on the
back side of the ET Enclosure. Splice the patch cable to the user supplied
cable, using the direct burial splice kits.
It’s very important that each plug is completely seated on to the
connector and the locking ring turned 1/4 revolution clockwise.
Failure to seat the plug completely could cause corrosion and
water damage to both the enclosure and the sensor cable.
The splice and wire nut must be completely immersed into the
silicon gel inside the splice tube to be waterproof.
