3 COMPONENTS
This chapter describes the components of the IGW/400-CAN shown in chapter 2 and
gives a short overview about their respective functions.
3.1
14-Pin Environment Interface
The environment interface is used to connect external devices to the two CAN channels,
the RS232 interface (RxD / TxD only) and to the two GPIOs.
Furthermore the environment interface is used to connect the power supply unit via the
power supply adapter cable to the pins 1 and 2 of the environment interface. The
IGW/400-CAN needs a supply voltage of 6 - 30 VDC to work.
Caution:
Providing the IGW/400-CAN with a supply voltage higher than 30 VDC could
damage the IGW/400-CAN!
3.2 Power
LED
The green power LED indicates a present supply voltage. This LED is on when the
IGW/400-CAN is provided with a voltage of 6 - 30 VDC by the power supply. If this
LED is off, check the connection between the power supply and the IGW/400-CAN.
Check also if the power supply is set to 6 - 30 VDC. The default setting of the power
supply is 12 VDC.
3.3
WLAN Activity LED
The red WLAN activity LED indicates activity on the WLAN interface. If this LED is
off, check the WLAN connection settings of the IGW/400-CAN.
3.4
RS232 Connector (UART1)
The IGW/400-CAN is equipped with a standard RS232 connector named UART1. This
interface comes with a 9-pin Sub-D male connector. The pin assignment of UART1 is
identical to the COM port assignment of a PC, so it is possible to use a standard cable.
3.5
Reverse SMA Connector for WLAN Antenna
The reverse SMA connector is used to attach the WLAN antenna to the IGW/400-CAN.
3.6
10/100 Mbps Ethernet Interface
The IGW/400-CAN allows Ethernet connectivity with a speed up to 100 Mbps. The LAN
interface of the IGW/400-CAN is a standard RJ45 Ethernet interface. The LAN interface
is an alternative to the WLAN antenna. You cannot use the LAN interface and the
WLAN antenna at the same time.
