CANgate Hardware
Connectors and LEDs
CANgate consists of a small aluminium box with a DE9 connector on each end and six LEDs on the top face.
Host RS232 Port
The female DE9 is used to connect to an RS232 port on a host computer or data logger. The pin-out follows the standard
DTE (Data Terminal Equipment) layout as used on a PC. That is:
Pin Signal Function
1 -
2 RXD Receive Data input
3 TXD Transmit Data output
4 -
5 GND Ground
6 -
7 RTS Request To Send output
8 CTS Clear To Send input
9 -
Note that the RTS and CTS pins are only used if hardware handshaking is selected (see Configuration (P11))
CAN/GPS/Power Port
The male DE9 is used to:
supply power to CANgate (10-30V DC)
connect to two separate CAN buses
connect to the RS232 interface (and possibly power) on a GPS unit
The pin-out is as follows:
Pin Signal Function
1 5V out +5Vdc output (200mA max)
2 GND Ground
3 CAN1-HI CAN port 1 – high (+)
4 GPS RXD GPS port – Receive Data input
5 CAN1-LO CAN port 1 – low (–)
6 CAN2-HI CAN port 2 – high (+)
7 CAN2-LO CAN port 2 – low (–)
8 GPS TXD GPS port – Transmit Data output
9 POWER in +10-30V DC power input
LEDs
The LEDs are used to indicate activity on the various ports:
LED Label LED Colour Function
Power red on while CANgate is powered
RS232 Tx red flashes when characters are transmitted to host port
RS232 Rx green flashes when characters are received from host port
CAN 1 Rx blue flashes when a CAN frame is successfully received from CAN port 1
CAN 2 Rx red flashes when a CAN frame is successfully received from CAN port 2
GPS Rx green flashes when characters are received from GPS port
Note that the CAN LEDs will only flash on receipt of CAN frames which match CANgate's current hardware filter settings. If
CANgate has not yet been programmed to receive CAN data then the LEDs will not flash, even if there is traffic on the
connected bus.
