Figure 3.5 Baud rate value
Among them, CAN1 in "CAN1b" represents the CAN1 channel, and b represents the
baud rate configured by the device through automatic identification. In "CAN2a",
CAN2 represents the CAN2 channel, and a represents the baud rate configured by the
device by configuring the DIP switch.
Notice:
1. The notepad file in the removable disk is a read-only file and can only be viewed.
The value in this file cannot be manually modified to change the baud rate of the
device.
2. GCAN-208-1 has two independent CAN buses. During automatic identification, it
will start with CAN1 first, and then CAN2 will be identified after CAN1 has been
identified. If the CAN light is always red and does not flash, it means that the
recognition is not successful. At this time, you need to check whether the wiring and
terminal resistance are correct. After the recognition fails, the module will
automatically adopt the value of the baud rate of the DIP switch when it is powered
on again.
Restore factory settings (clear the automatic identification record of the device): Turn
all the 8P dial switches to the digital side, then power on the device, and then press
and hold the reset button until the CAN light is red and flashes to make the device no-
load identification. After all CAN channels fail to be identified, power on again to
restore the factory settings.
3.1.4 Modify the device baud rate
When you need to modify the baud rate of the current device, you can do as shown in
the following flowchart 3.6.
