The INTELETRACK TELEMETER is an end-of-train monitor system. The system measures the air-brake pressure or vacuum at the end of the train and transmits the information to the driver in the cab via a radio link. More than 500 Inteletrack telemeter systems are in operation in South- Africa, and several systems are in operation in other countries around the world. The Telemeter system can interface to track-side equipment like low cost dragging equipment detectors, hotbox detectors and point switching equipment. A complete telemeter system consists of a cab unit mounted or stowed in the cab of a train where the crew operates and a rear unit mounted with a clamp on the last wagon of the train.
The cab unit consists of a microprocessor, radio modem and 16 digit alpha-numeric LCD display, with backlighting for night visibility, and an integral antenna. The cab unit receives the messages from the rear unit via a radio-modem. The air-brake pressure or vacuum is displayed on the Cab unit's LCD display. The status of the cab and rear unit’s batteries are also continuously displayed. If the pressure drops below 400 Kpa or the vacuum is less than -35 Kpa, a buzzer will be sounded and a red alarm light will flash. If communication is lost with the rear unit, the cab unit will display an error message "NO COMMUNICATIONS". All alarms are logged in a non-volatile ram buffer. The INTELETRACK Telemeter system is designed to be a simple, rugged and reliable system. Maintenance is done by changing modules. All components are readily available from local suppliers.

The new INTELETRACK TELEMETER is an end-of-train monitor system. The system measures the air-brake pressure or vacuum at the end of the train and transmits the information to the driver in the cab via a radio link. This new version of the telemeter is designed according to AAR S-5701 specifications. A complete telemeter system consists of a cab unit mounted or stowed in the cab of a train where the crew operates and a rear unit mounted with a clamp on the last wagon of the train. The INTELETRACK Telemeter system is designed to be a simple, rugged and reliable system. Maintenance is done through changing the modules.

GSM/GPS Asset tracker
When information about moving assets is needed, the VI Tracker can be considered. This small unit can fit snugly into small spaces and does not need external connections to a power supply to function, although operational periods may then be limited. The VI Tracker was designed to be a small tracking unit, reporting GPS coordinates and other status messages via the GSM network to a client server via GPRS or to designated cell phone numbers via SMS. The server may be configured to display the information on a web page or to send emails to designated email addresses.
Hardware-wise, the unit consists of two PCBs – one master PCB and one GPS/GSM module. The master PCB features one USB2.0 port, one RS232 port and a real-time clock (RTC) to keep track of time when the GSM network is unavailable or when the GPS does not have signal. The backup battery is not chargeable, but will last for approximately one year when used in backup mode (no external power connected). This may be replaced with a rechargeable super capacitor with a backup lifetime of approximately 10 days. The power management on the master PCB allows recharging of a 3.8V lithium-ion polymer battery over the USB port. Power is selectable between USB power (GSM and GPS off; 5VDC 500mA) and 5V external power (GPS and GSM can now be used; 5VDC 3A). Another option may be to include some sort of storage for logging or other purposes, such as NAND flash memory or a micro-SD card. On request, the PCB may also expand to include a 10/100 Mbps Ethernet port.
Input Voltage 3.6VDC – 6.0VDC (5VDC nominal). Input Current 3A (2A spike for GSM); 500mA USB. Dimensions 70mm x 56mm x 25mm approx without housing. Rate of Reporting Configurable* (three times daily) SIM Card One push-push mini SIM card connector RS232 baud rate 57600 RS232 data 8-bit RS232 parity None RS232 stop bit(s) 1 bit RS232 Flow Control None * Software may be changed upon request.
With a Lithium battery and a reporting rate of 5 minutes (configurable), the unit may operate up to 3 days without a external power source.
Dragging Equipment Detector
The Inteletrack DED® - Dragging Equipment Detector consists of a mechanical device with automatic reset-able detector plates inside and optionally outside the railway tracks on either side. As the dragging equipment passes over the detector plate, the detector is activated and starts transmitting the emergency code consisting of the detector plate number, which side of the track was activated and the detector's battery status.
The unit can be used with the Inteletrack Telemeter system, or as a stand-alone unit with an optional interface to standard signaling systems. If the system is used with the Inteletrack Telemeter system, operation is as follows. When the rear Telemeter unit passes the detector plate and the plate is triggered, the low cost electronic detector unit will be activated for a certain time. The rear telemeter unit then receives this message and transmit the alarm to the cab unit located in the front of the train with the train crew. The alarm is logged in the memory of the cab unit. The DED® system can also be fitted with a long range radio and power source to send messages directly to the cab unit. The low cost electronic detector unit of the DED® will operate for more than ten years with its internal battery. The installation is simple and only requires the removal of ballast rock underneath the rail and the clamping of the DED® to the railway line. No power or wiring is required.
Options -Cable connection or Radio link on Trigger. -Customized to fit on/in most type of rails.
