Introduction

The CM910 Cellular Modem is the latest addition to the QTech Remote Control product line.

It features a GSM/GPRS/UMTS (3G) cellular modem which is capable of connectivity with all
current New Zealand telecommunication companies (Spark, Vodafone and 2 Degrees) for
both SMS and data communications.

The modem is controlled by an AT command interface via either a standard serial RS232 or
by USB connection. It offers a wide range of operating voltages from 9-24V DC.

By default the yellow status LED indicates the current state of the modem. It can be user
custom configured to match your application providing both solid and flashing states.

This modem is suitable for:

 Cellular IP Data Communications

A communication option for an XL4 RTU to the DATRAN SCADA base station. This
requires XL4 firmware v6.05+, QTech Workbench v1.8.14 or above and DATRAN VI

Aerial Connection

Carefully connect the aerial. Do not operate the CM910 without an aerial connected. Refer
to Technical Details section for alternatives. The aerial must be vertically orientated.

Install the SIM Card

Before installing the SIM card, ensure that it is activated. We recommend you insert the SIM
into a regular cell phone to check this. Carefully remove the CM910 cover by prising the
side panels close to the retaining dimples.

Locate the SIM card holder adjacent to the USB and RS232 connectors. Push the top part of

the holder in the direction of the “Open” arrows (away from the aerial). Carefully insert the

SIM card from your chosen Telco. Be careful to orientate the card correctly, once in place
carefully slide the plastic retainer towards the aerial to “Lock”.

Unlock Holder Lift & Insert SIM Close Holder Lock Holder

Note – The SIM card must be a “full size” card, not a “micro SIM”.

Installation and Operation Notes

1. The CM910 is over voltage protected by a 30 volt Zenner diode. Voltages greater than this
will blow the internal 500mA fast blow fuse.
The supply voltage should be clean, continuous and transient free.

Warning – Do NOT use Switch Mode Power Supplies (SMPS) with this product. The DC

power supply used for this product MUST have a grounded negative or be a “linear”

transformer based plug pack. The reason is that the aerial, programming port and external
connections can provide exposed earth points and the SMPS can impose an AC voltage on the
DC ground, which can lead to damage. Suitable cost effective plug packs are available from
QTech P/N PD5412, PD5413 & PD5414.

2. The reliability of all cellular products is dependent on good signal strength. Before deciding
on the Telco to choose, please check coverage. We suggest that a cellular phone is taken to
site, to check the signal strength, i.e. how many “bars” are displayed.
The supplied stub aerial (P/N PD9230) should be suitable for locations with good cellular
coverage (full bars) and where the CM910 is in a non-conductive enclosure (plastic etc).
Other external mounting aerial options are available; contact your equipment supplier for
more details.

Warning – Do NOT operate the CM910 without an aerial connection.

3. Can be used as an AT command control interface to a PC. Please refer to Installation and
Operation Notes.

4. Used as an AT command interface to either

 XL4 RTU via the provided DB9 (male) to RJ45 serial cable
 Pc via a standard straight through RS232 cable

5. Provides connectivity with all current New Zealand telecommunications companies (Spark,
Vodafone and 2 Degrees).
