2.1 Connection
CG-ARM7/D/E has a male and a female SUB-D 9 plug to connect
two CAN segments. An USB type B connector is intended for
configuration purpose and for download of new firmware. Power may
be supplied to the device either via the SUB-D or the USB
connector. For the HS/LS version the CAN connection has a slightly
different connection scheme. The assignment is described in chapter
"3.1 Pin assignment".
2.2 Operation
To start up the gateway just connect the power supply, the device
starts up automatically. As soon as the automatic diagnostic process
is successfully completed the green power LED lites up permanently.
Important note: Ex factory the device offers no configuration and
must be configured before its first run. Configuration instructions for
the gateway are located in chapter "2.3 Configuration".
2.3 Configuration
The gateway configuration process consists of two steps:
• Creating a configuration file
• Loading the configuration into the device
2.3.1 Configuration File
The configuration file is a text file with the extension *.gcf. This file
holds all data needed by the gateway for operation. A complete
sample configuration is located in chapter "4.1 Configuration File
Example".
The values can either be entered in decimal or hexadecimal
notation. Using the hexadecimal notation, the character 'x' has to be
entered directly before the particular value.
