The configuration can be permanently stored in the CAN-AIR/2 memory. It is also possible to save the configuration as a file on a PC and to open it again, e.g. to configure a second CAN-AIR/2 in the same way for Bridge mode operation. Start the program canairconfig.exe as described under Software Installation step 3. -

Page 23: Can Baud Rate Setting
To set the baud rate of the CAN bus select an adequate baud rate. The CAN Baudrate has to be set to the same value as the other nodes on the CAN bus. If two CAN-AIR/2 are operated in "Bridge"-mode both CAN-AIR/2 could be set to different CAN- baud rates. -
Page 24: Rf-Channel Setting
In the frequency range from 2.404 GHz (RF-channel 04) up to 2.479 GHz (RF-channel 79) the choice of 76 channels in steps of 1 MHz is possible. Because the CAN-AIR/2 occupies 2 MHz as the bandwidth, neighbouring channels cannot be used. The spacing between channels in use must be at least 2 MHz when using within the transmission range. - Page 25 CAN-AIR/2 Configuration For the RF-Transmission CAN-AIR/2 uses the 2.4 GHz ISM-Band. This frequency range is also used for WLAN- (IEEE 802.11) and Bluetooth- (IEEE 802.15) services but with different RF channel assignments. Direct communication with units of these other standards and the CAN-AIR/2 is not possible.
