How To Install a CTM-200
The CTM-200 includes a flexible mounting bracket that has eight 5mm mounting holes suitable for number 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, clip the CTM-200 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).
The CTM-200 can be installed in any orientation, but it is suggested that it not be mounted with the interconnect face directed upwards as this can allow liquids to enter the CTM-200.
The CTM-200 should be mounted in an area where it is free from excessive dust and liquids.
The power cable has three wires:
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-200 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.
- Red +V supply (+5.5 to +36VDC)
- Black 0V return
- White Standby (+V for operation, Off for standby)
Plug one end of a standard Ethernet patch cable into the CTM-200’s 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.
The antenna used with the CTM-200 must be a type suitable for operation on the network for which the CTM-200 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”).
The CTM-200 antenna connector is a standard SMA female type that requires the antenna cable to use a male SMA connector. The CTM-200 can be provided with alternate antenna connector types – contact Cypress Solutions for details.

The GPS antenna used with the CTM-200 (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 CTM-200 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-200 device is PC-CARD based or Express card/module/USB based. The CTM-200 can be provided with alternate antenna connector types – contact Cypress Solutions for details.

The serial data port is a standard DB9 female connector configured as Data Communication Equipment (DCE) and is wired as per the table below.
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-200 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.
| DB9 Pin | Signal | Name | Direction |
| 1 | DCD | Data Carrier Detect | CTM-200 to PC |
| 2 | RxD | Received Data (by DTE) | CTM-200 to PC |
| 3 | TxD | Transmitted Data (by DTE) | PC to CTM-200 |
| 4 | DTR | Data Terminal Ready | PC to CTM-200 |
| 5 | GND | Signal Ground | |
| 6 | DSR | Data Set Ready | CTM-200 to PC |
| 7 | RTS | Request to Send | PC to CTM-15X |
| 8 | CTS | Clear to Send | CTM-200 to PC |
| 9 | RI | Ring Indicator | CTM-200 to PC |

The I/O port provides for the control of 4 external devices and for monitoring 6 external sensors. Connections are made via the 14 position connector.
- Output 1
- Output 2
- Output 3
- Output 4
- Power (Common Ground)
- Power (Power supply output – fused)
- Differential input 1 positive
- Differential input 2 positive
- Differential input 1 negative
- Differential input 2 negative
- Single ended input 3
- Single ended input 4
- Single ended input 5
- Single ended input 6
The 4 outputs are configured as “open drain” which means that they can be directly connected to energize external relays, lamps or other DC devices. Maximum supply voltage is 36 volts, with a maximum load current of 500mA. Recommended wire gauge for use with the connector is 16AWG. Note that the OUT GND connection is referenced to the CTM-200’s supply ground.
The 6 inputs may be configured in the CTM-200 for monitoring a digital DC voltage state or an analog DC voltage. For digital state monitoring the minimum input voltage is 0 volts while the maximum is 36 volts. The threshold detection voltage is 2.5 volts with 1 volt of hysteresis. Note that the IN GND connection is referenced to the CTM-200’s supply ground.
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 CTM-200’s supply ground.
