Gateway Series
Gateway-400
onboard counting computer
The GW-400 communication Gateway is a compact onboard counting computer that works together with the sensors from our DA-Series to create a highly accurate and precise Automatic Passenger Counting (APC) system. The ultra-compact GW-400 is fully autonomous or can be easily connected to other existing onboard computers. Its built-in power supply can adapt to a wide range of voltages.
These counting computers are installed inside the vehicles. At each stop or station, they receive the signals from the DA-200 or DA-400, transforms them into counting data, which are then stored in the GW-400’s memory until it receives a download command.
The data is usually transferred, directly from the GW-400, via a wireless module to the ground data analysis server. This saves on cabling costs and installation time. What’s more, the GW-400 is flexible and cost effective. Up to four GW-400s can be installed inside a vehicle to reduce cabling complexity or avoid problems that could be encountered in older vehicles.
Multiple communication options Available
Our products are designed to be easily integrated in new vehicles as well as in an existing fleet. A wide range of communication options are available.
- Ethernet-LAN / PoE;
- 802.11 b/g
- Cellular GPRS/GSM
- Wifi
- Long-Range Wireless
- Serial RS-485 / RS-232
- Other options
The GW-400 records:
- “In” and “Out” counts per sensor, per door at each stop
- Time of arrival and departure at each stop
- Stop location and distance (with GPS option)
- Distance (if odometer signal available)
- Time of passage in front of stop or station without vehicle stop (virtual signpost)
- Speed of door opening and closing
- Detailed diagnostic information on sensors, GPS, door signals, system integrity, etc.
Connectivity
- Cabling significantly reduced
- No connection to the door system is required when using the integrated optical door detection of the DA-400
- Interface to onboard computer using customized or industry standard protocols
- Automatic download capacity
- Very light maintenance required during entire life of vehicle
- ID chip technology provides automatic reconfiguration when unit is replaced
- The GW-400’s rugged design resists harsh environmental conditions often found in public transit vehicles
Design
- Accuracy between 97.5% and 99.5% has been proven many times without using any correction factors
- Very compact and lightweight
- Low power consumption: typically 5-7 W
- Quick installation with bolt-on design
- Remote diagnostics and software upgrades
- Large range of voltage compatibilities
