2 Installing Your Modem
2.1 Mounting
The CTM-15x is provided with a flexible mounting bracket that has eight 5mm mounting holes suitable for
#10 screws. These may be used to screw or bolt the device to a suitable surface – take care not to over-
tighten these screws and damage the bracket. Once this has been installed in the required location the
modem clips into the 4 tabs of the bracket. The bracket can be used as drill guide template. There are a
total of 8 mounting holes, (2, 4 hole patterns, 2 x 5.5 and 1.75 x 3.75)

© 2009 Cypress Solutions Complete Manual: CTM-15X Firmware 1.2.0
(Revision 1.0)
131BInstalling Your Modem
The modem can be installed in any orientation, but it is suggested that the modem not be mounted with
the interconnect face directed upwards as this can allow liquids to enter the modem.
The modem should be mounted in an area where it is free from excessive dust and liquids.

© 2009 Cypress Solutions Complete Manual: CTM-15X Firmware 1.2.0
(Revision 1.0)
141BInstalling Your Modem
2.2 Connecting the Power Cable
The power cable has three wires:
Red +V supply (+9 to +36VDC)
Black 0V return
White Standby (+V for operation, Off for standby)
A 5 Amp “slow-blow” fuse is recommended in the +V supply line.
The operate/standby switch may, for example, be the accessory position on a vehicle ignition switch. In
order to minimize the acquisition time of the GPS module in the CTM-15x at power on, it is recommended
to keep the +V supply connected – this will provide the “keep-alive” power required by the GPS module
to maintain its internal almanac.
2.3 Connecting the Ethernet Cable
Plug one end of a standard Ethernet patch cable into the CTM-15x Ethernet port, and the other end into
the LAN device, PC or Ethernet peripheral. The Ethernet port is compatible with 10Base-T or 100Base-T
connection types.
2.4 Mounting and Attaching the Cell Antenna
The antenna used with the CTM-15x must be a type suitable for operation on the network for which the
modem is activated. For CDMA/EV-DO/GPRS/HSPA networks this is typically a dual band 800 Mhz and
1900 Mhz antenna.
For optimum performance the antenna should be mounted in a vertical orientation as high up as possible
and with clear line of sight in all directions. For regulatory purposes it must be mounted in such a position
as to maintain a separation distance from any person of at least 20cm (8”).

© 2009 Cypress Solutions Complete Manual: CTM-15X Firmware 1.2.0
(Revision 1.0)
151BInstalling Your Modem
The modem antenna connector is a standard SMA female type that requires the antenna cable to use a
male SMA connector. The CTM-15x can be provided with alternate antenna connector types – contact
Cypress Solutions for details.
2.5 Mounting and Attaching the GPS Antenna
The GPS antenna used with the CTM-15x (with GPS) must be an active type with gain of at least 26dB and
compatible with a 3.3 volt dc supply provided directly by the modem over the coax cable. The antenna
installation should typically be on an upper horizontal surface of a vehicle with a clear 360 degree view of
the sky.
The GPS antenna connector is a standard MCX type or SMA female depending on whether the CTM-15X
modem is PC-CARD based or Express card/module/USB based. The CTM-15x can be provided with
alternate antenna connector types – contact Cypress Solutions for details.
2.6 Serial Data Cable Connection
The serial data port is a standard DB9 female connector configured as Data Communication Equipment
(DCE) and is wired as per the table below.
DB9 Pin Signal Name Direction
1 DCD Data Carrier Detect CTM-15x to PC

6 DSR Data Set Ready CTM-15x to PC
7 RTS Request To Send PC to CTM-15x
8 CTS Clear To Send CTM-15x to PC
9 RI Ring Indicator CTM-15x to PC
Serial data ports on most computer equipment are configured as Data Terminal Equipment (DTE) with a
DB9 male connector. A standard serial data cable will allow for direct connection of the CTM-15x to most
computer and terminal equipment. In some cases it may be necessary to insert a “null modem” or
“gender changer” in the serial data line in order to correctly connect between the devices.
2.7 Connecting to the I/O Port
The I/O port provides for the control of 4 external devices and for monitoring 6 external sensors.
Connections are made via the 12 position connector.

(Revision 1.0)
172BOperating Your Modem
For analog voltage monitoring the measurement range is 0 to +10 volts with 10mV resolution. The input
can withstand up to 36 volts. Note that the IN GND connection is referenced to the modem’s supply
ground.
3 Operating Your Modem
3.1 Automatic Power Control
The supply voltage must be a minimum of 9VDC for the CTM-15x to operate. With the power applied it
will power-up in its operating mode.
Note: In some vehicle operation, when starting the engine the vehicle supply voltage will dip below 9VDC
momentarily. This will cause the modem to reset as the power dips below 9VDC. If continual operation is
required, contact Cypress Solutions for an accessory power regulator that plugs in-line with the modem
power supply. This power regulator will prevent unnecessary resets.

been turned off. This enables the modem to continue sending position reports or be used for data
operations even after the vehicle ignition has been switched off – e.g. for short duration driver breaks.
When in its power shutdown mode the modem may be configured to resume full operation by either the
standby/ignition signal becoming active, an input event occurring, or the power OFF timer expiring.
3.2 Power Consumption
The power consumption of the CTM-15x modem will depend on its supply voltage, its current operating
function and its RF environment.
The following table is provided to assist application integrators in defining the power requirements for
their specific application.

3.3 Device Reset
The CTM-15X modem may be manually reset via the front panel using a <1mm diameter (0.04”) wire tool
(a standard paper clip). This can be used to cause the modem to reset its operation, or to enter its
standby power mode.
reset: Press and hold for 0.25 to 1 second

3.5 Making a Wireless Network Connection
The CTM-15X will attempt to connect to the wireless network whenever power is applied, when
configured with cmd mode 2 (default)
If no wireless network connection is available the IP address will be given as 0.0.0.0. This can be queried
using cmd ipadr For Sierra Wireless RF devices, wireless signal strength information can be queried using
cmd rssi. These values for both 1x and EV-DO are given in dBm with range typically -60dBm (very good) to
-105dBm (weak).
With the wireless network connection active you may now open Windows® applications that will make
use of this connection – this includes email, web browsers, and VPN connections.
3.6 GPS Operation
The GPS module in the CTM-15X Modem will continuously track the unit’s position whenever power is
applied and the GPS antenna has a clear view of the sky. The time taken for the module to achieve a valid
positional fix is determined by the previous state of the unit:
For a “cold” start (after all power is applied to the modem) the acquisition time typically will be less than
50 seconds.
For a “warm” start (standby power is maintained to the CTM-15x) the acquisition time will typically be
less than 38 seconds.
For reacquisition (after the GPS module has temporarily lost signal) the time to acquire a valid position fix
is typically less than 2 seconds.
The GPS information can be sent by the device as a message in any of the configured reports.
The GPS receiver uses the WGS-84 datum.
