Components Page3
Power Components
You will need to supply power to the CTM site, using one of the following
options.
✦
If AC power is available at the CTM site, use the power adapter supplied with this
kit.
✦
To power the CTM with solar power, use the Solar Power Kit (#7708) and 6.5-
Amp-Hour Battery (#7711).
If solar power is used, it will be necessary to switch the power to the
phone so that it is on for only limited periods in order to conserve the
power drawn. Two alternatives are available:
✦
Alarm Output Module (#7736)
✦
Timer (#7682)
The Timer is recommended unless the Alarm Output Module is
being used for other purposes.
WeatherLink Components
You will need the following item from your WeatherLink package:
✦
PC COM Port Adapter
On older versions of the WeatherLink, this adapter was labelled AT
Adapter.
Optional Components
The following optional components may be necessary for your installation.
✦ Radio Surge Protector (#7681SSC)
If the CTM is located in an area where lightning strikes are a possibility,
use the Radio Surge Protector to provide surge protection between the
antenna and the CTM. Davis recommends the use of the Radio Surge
Protector in all installations .
✦
Antenna Mounting Bracket (#7684)
The hardware provided with the Antenna Kit enables you to mount the
antenna on the Sensor Mounting Arm (#7702). If you want to mount it
on a pole, post, or wall, use the Antenna Mounting Bracket.
Note: The CTM’s antenna should be located as high as possible and away from buildings and
other obstructions, if possible. It is best if the path between the antenna and the near-
est phone company cell antenna is completely unobstructed (line-of-sight). Intervening
trees and other vegetation can reduce the signal intensity.
✦ Handset (Motorola #SL2504) and Hang-Up Cup Assembly (Motorola #SL9854)
If you wish to originate or receive voice calls at the weather station/
CTM site, you will need to order the handset and hang-up cup assembly
from Motorola. Consult the Motorola Contact and Parts Information
Sheet for more details.

(grey), the green CTM power wire to terminal 3 (orange), and the red CTM power wire
to terminal 4 (orange).
2. On the other side of the terminal block, connect the black power adapter wire to ter-
minal 1 (grey) and the red power adapter wire to terminal 4 (orange).
3. Plug the power adapter into a power outlet.
Run The Modem Configuration Program
Finally, use the supplied modem configuration program to configure the CTM.

3. Type A:\CONFIG and press Enter (or choose Ok).
The Wireless Configuration Program dialog box appears.
4. Select Cell Phone Modem from the Modem Type drop-down list.
5. Select the COM port to which the CTM is connected from the COM Port drop-down list.
If you don‘t know the COM port number, choose COM 1. If you get a pro-
gram error when attempting to configure the CTM, try again using COM 2,
and so on, until you find the correct COM port setting.
6. If you fully understand the CTM’s AT command set and wish to configure the CTM dif-
ferently than the default configuration, choose Advanced. You may then enter the
desired AT commands and choose Execute Command to execute the string. Choose
View Conf to view the CTM’s current configuration.
The default configuration should work in almost all installations; we do not
recommend using the Advanced setting option.
7. When finished, choose Configure.
The program will attempt to locate and configure your CTM. If you encoun-
ter an error, make sure you have selected Cell Phone Modem and then try
different serial ports until the configuration completes successfully.

NSTALLATION
Follow the instructions below to install the various components of your CTM.
In many cases, you will need to use the installation manual supplied with the
component for specific instructions.
Note: Before beginning the installation, disconnect the cables attached in order to configure the CTM.
Installing Antenna
You may mount the antenna on either the Sensor Mounting Arm or on a pipe,
post, or wall using the Antenna Mounting Bracket (#7684).
✦
Installing on Sensor Mounting Arm (SMA)
Attach the antenna to the ground plane as shown below; screw on until
snug. Attach the ground plane to the SMAusing the #8-32 x
¾
" screws,
flat washers, split lock washers, and hex nuts as shown below.
Note: It may be necessary to drill one or two holes in the SMA to accommodate the antenna/
ground plane assembly. If so, use the holes in the ground plane as a guide and drill holes
using a 7/32" (5.5mm) drill bit.

Installing Solar Power Kit & Battery
Consult the manuals supplied with the appropriate component for instruc-
tions. Note the following, however, as you proceed with the installation.
✦
Use tab adapters to attach wires to the battery.
Before installing the battery, slide the tab adapters onto the terminals.
Attach the black battery wire (supplied with this kit) and the black wire
from the battery cable (supplied with the Solar Power Kit) to the tab
adapter connected to the ground (black) terminal. Attach the red battery
wire (suppplied with this kit) and the red wire from the battery cable
(supplied with the Solar Power Kit) to the tab adapter connected to the
positive (red) terminal. Make sure you have access to the free end of the
battery wires and the battery cable once the battery is installed.
✦
Do not connect the solar panel or the battery to the regulator circuit.
Make sure you have made no connections at B1 and B2 on the regulator
circuit before proceeding.

circuit. Connect the other end to the negative (-) terminal at B on the AOM.
✦Connect one end of the white AOM wire to the Wht terminal at B4 on the regula-
tor circuit. Connect the other end to terminal 2 (green) on the terminal block, on
the same side as the power wires.
Installing Handset and Hang-Up Cups
If you wish to originate or receive voice calls at the weather station/CTM site,
install the handset and hang-up cup as shown below.
Note:If you install a handset you must not turn power off at the handset when leaving the station
because this overrides the Timer or Alarm Output Module control. The handset power must be
on for the “power saver” switching to “wake up” and receive calls from the WeatherLink soft-
ware.
✦Installing the Handset
Insert the phone plug on the end of the handset cable into the jack on the
side of the CTM.
✦Installing the Hang-Up Cups in Complete System Shelter (CSS)
Use the cup as a guide and drill holes in the upper right corner of the CSS
door with a ⅛" (3 mm) drill bit. Secure the cup using the #4 screws,
washers, star washers, and nuts as show below. Use the #4 x ¾" screws in
the two lower holes and the #4 x ⅜" screws in the two upper holes. Make
sure the cup is oriented correctly, with the white bumper at the top.
