Au J1939 Message Center System (MCS) includes a handheld device and computer software with a graphic user interface (GUI).
Au J1939 MCS is a turn-key solution that displays about 20 SAE-J1939 parameters on a computer screen.
The GUI could serve as a secondary display on trucks, school buses, recreation vehicles (RV), marine vessels, or any vehicles with SAE-J1939 controller area network (CAN).
Major Hardware Features
Au J1939 MCS box is a handheld device with one LED and two DB9 connectors (one is a DB9 female connector on the RS232 side, the other is a DB9 male connector on the BUS side). The major features of the device are listed below:
Power Supply: Operating range: 10V ~ 32V DC; nominal voltage: +12V DC or +24V DC
Operating Electric Current: 65mA typical, 250mA max
Operating Temperature: -40°F to 185°F (-40°C to 85°C)
Size: 3-1/8 inch L X 1-11/16 inch W X 13/16 inch H (78mm X 42mm X 21mm)
TVS (Transient Voltage Suppressor) protection on J1939 and J1708/J1587 bus
Enclosure Color: Black and translucent red
1 LED for communication event indication
1 RS232 interface (DB9 female connector): can connect to a PC or any device with RS232 serial port( default RS232 baud rate: 115.2K)
1 BUS interface (DB9 male connector): can connect to J1939/CAN network and a power supply (+14.2V / 24V DC nominal). The pin-out of the DB9 male "BUS" interface is illustrated in following pin-out diagram:

Three ways of PC connection
Au J1939 MCS device has an RS232 interface. It can be connected to a PC in one of three ways
It can be connected to the RS232 (serial) port of a PC through an RS232 serial extension cable (part#: CBL-RS232-01)
It can be connected to the USB port of a PC through a USB to RS232 converter cable (part#: CBL-USB-232)
With an optional built-in Bluetooth module, the J1939 MCS device can communicate with a computer through a Bluetooth dongle
Typical topology
A typical application of Au J1939 MCS in SAE J1939-15 network is illustrated here:
Major Software Features
Automatic CAN baud rate detection
Ease of Use: Displays SAE-J1939 messages from CAN network without the requirement of decent J1939 knowledge/experience or very complicated configuration settings.
