1) INTRODUCTION
This manual gives instructions to distributors who are purchasing a GSM module from Skye, and
fitting the Siemens TC35iT module themselves.
However, if you have purchased the TC35iT from Skye we will have already installed it in its
housing however it is possible that you may have to reprogram the modem for your own local
GSM network.
The Siemens TC35iT modem is dual band for use with a 900 or 1800 MHz GSM cellular telephone
system only. An airtime contract and SIM card must be obtained from the mobile phone network
provider. This can be a standard “Voice” contract with a Data number added, or some network
providers offer a “Data only” contract. You need the Data “telephone” number to dial up the
MiniMet weather station. The Voice telephone number will not work.
When requesting the Data number from the network provider, please ask for:
1. Circuit Switched data number (modem type connection)
2. 9600 bps
3. 8 data bits, No Parity bits, 1 Stop Bit
4. Non-Transparency enabled (also known as error corrected or “RLP”)
Connection to the remote MiniMet or DataHog logger can be made from the office PC which is
fitted either with a standard modem connected to the PSTN telephone line or via a second TC35iT
cellular modem and SIM card using the Skye MOD3 unit. Please see the Chapters 3.1 and 3.2 for
setting up these two options.

TC35iT Installation & Programming Manual

2. INSTALLING THE SIEMENS TC35iT MODEM
This chapter refers to the remote MiniMet or DataHog GSM housing enclosure (with the green
label).
Make sure no power is available to the GSM Modem Unit before proceeding.
Remove the lid from the Skye GSM Modem Unit by unscrewing the 4 corner screws.
The Siemens TC35iT is supplied with a short aerial lead and connector only. It has 2 mounting
holes which can be used to fix it to the aluminium mounting plate inside the Skye GSM Modem
Unit. See Figure 1.
There are 2 sockets on the TC35iT. The Skye GSM Modem Unit has a grey 9 pin D connector and a
small clear connector with 6 gold contacts which match these sockets. Push the clear connector into
its socket, connect the grey D connector and screw up to secure.
Before connecting the aerial remember to feed the aerial cable through the cable gland in the
base of the GSM Modem Unit. See Figure 2. Screw together the 2 aerial connectors and make the
excess cable tidy. Tighten the cable gland over the ‘built up’ portion of the aerial cable to make a
waterproof seal.
To install the airtime contract SIM card, locate the small black tray marked SIM on the side of the
TC35iT itself. Push the little yellow button beside it to release the tray, insert the SIM card (it will
only go in one way) and replace the tray, pushing fully home.
NOTE: before installing the SIM card it is a good idea to insert it into a hand phone to check its
functionality. You may need to switch off the PIN code request function, we would also
recommend switching off all divert calls (e.g. divert to voice mail if not answered etc).
The TC35iT then requires programming before use (see below).

TC35iT Installation & Programming Manual

3. PROGRAMMING THE TC35iT MODEM
It is necessary to change the factory settings of the Siemens TC35iT modem suitable for
communication with the DataHog or MiniMet logger. When the TC35iT is purchased through Skye,
we will have already done this initial programming for you (the default setting is described in
Chapter 3.1 for use with a standard PSTN telephone line).
However in some countries we have found that one or two settings are slightly different to those
used in the U , so you may have to change these. You may need to seek advice from either a
local Siemens dealer, or the GSM network provider technical department, who should be able to
advise on different programming settings for your own country.
Programming the TC35iT is very easy and full instructions are given below. You will need the
special 'Modem Programming' cable (see Appendix 2 for details), the Skye GSM Modem Unit, an
aerial and a 12V battery or 12V power supply.
3.1 Using a standard PSTN telephone line at the PC end
In this case you will have just one Siemens TC35iT modem, fitted into the GSM Modem Unit
housing, which will be installed on the MiniMet mast.
The office PC which will dial up the station must also have a modem connection. This must be a
standard analogue fax / modem (internal or external to the PC) connected to an analogue
standard PSTN telephone line. An ISDN digital telephone line will not work.
PLEASE FOLLOW THESE INSTRUCTIONS IN ORDER, CAREFULLY. IF POWER IS APPLIED TO THE
TC35iT UNIT BEFORE OTHER CONNECTIONS ARE MADE, THE MODEM CAN BE PERMANENTLY
DAMAGED.
1. Disconnect the grey 9 pin D connector from the GSM Modem Unit to the TC35iT. Replace this
with the male end of the Skye 'TC35iT programmer' cable. Connect the female end to a serial
port of a PC.
2. Make sure the aerial is fitted to the TC35iT.
3. Connect a 12V battery (or power supply) to the GSM Module Unit using the red and black
'spade' connectors fitted to the thick white cable exiting the base of the housing. At this point
the red LED marked MODEM ACTIVE WHEN LIT should come on (in the bottom right hand side
of the PCB).
Start Windows HyperTerminal on the PC. To begin communications, configure the appropriate
Comm Port and use the settings 9600 baud rate, no handshake, no parity, 1 stop bit. If you are
unfamiliar with HyperTerminal please see Appendix 1.

3.3 Notes on TC35iT modem programming
The above settings have been tested on U networks only.
There is only one difference between the datalogger modem programme in Chapters 3.1 and 3.2,
that is instruction 13. The command at+cbst defines the type of modem connection as follows:

TC35iT Installation & Programming Manual

4. MODES OF OPERATION
The standard mode for operation of the GSM Modem Unit is for the modem to be powered and
on ‘standby’ to receive a call 24 hours a day.
There are some ‘jumpers’ on the electronics board which can change this mode of operation,
normally they will not need to be changed but it would be good to be aware of them.
See Figure 1 and Figure 3 showing the layout of the inside of the GSM Modem Unit. Just above
the red LED light which indicates whether the modem is active, there are a pair of jumpers marked
L12 and L13.
If there is a small black connector across the two pins of L13, then the system will operate in
standard mode and will power the modem 24 hours a day.
If there is a small black connector across the two pins of L12, then the system will never power up
the modem, this is a permanently OFF position, used for servicing etc.
If there is no connector across either L12 or L13 then the ‘telephone pager activator’ function is in
operation. The buttons in the centre of the electronics board, blue to Start and red to Cancel, will
activate the modem for the time period set by the ‘Pager ‘on’ / Test period link settings’ – see
Figure 1, Figure 3 and also the GSM TC35iT Modem Unit manual.
The ‘telephone pager activator’ option is only available in the U at the moment. If you are able
to locally source a standard numeric telephone pager, which is powered by a single 1.5V battery,
then it may be possible to use this option in your own country. Please contact Skye for details.
When the red LED ‘modem active’ is lit, then power is being applied to the TC35iT modem and the
green LED on the modem itself should flash slowly, about 1 flash per second. When a call is being
connected to the modem, this green LED will flash much faster. It will return to the slow flash as
soon as the call is finished.

Modem Power Control
The GSM Housing box encloses the GSM modem itself, plus electronics for controlling the
modem, the power supply and solar power regulator.
There are ‘power on’ options for timed operation, permanently on or permanently off. These 3
options are controlled by a set of jumper pins on the PCB as shown below.
First locate the 2 sets of jumper pins just above the LED marked ‘modem on when lit’ in the
bottom right hand corner of the box, next to the large orange terminal connector. There is a black
jumper provided to enable a short across the jumper pins as required.
1. Power to the GSM modem is in TIMER MODE (available only when a pager or clock is fitted)
when Jumper 1 or 2 are NOT shorted:
2. Power to the GSM modem is permanently ON when Jumper 2 is shorted:
3. Power to the GSM modem is permanently OFF when Jumper 1 is shorted:
