When an RS232 device is connected to a Cisco IR829 router, and the collected data is not being parsed correctly by the edge application, there could be several reasons for this problem. To troubleshoot the issue, the following steps should be taken:
Ensure that communication parameters like baud rate and parity are set correctly: RS232 devices communicate through a serial connection that requires specific communication parameters such as baud rate, parity, data bits, and stop bits. If these parameters are not set correctly, data may not be transmitted correctly, leading to parsing errors. Therefore, it is important to ensure that the communication parameters are set correctly.
Set the cable connections based on the PIN layout from the sensor vendor: The RS232 serial cable must be connected to the correct pins on the Cisco IR829 router and the RS232 device. The PIN layout may vary depending on the sensor vendor, and therefore it is essential to follow the instructions provided by the vendor to ensure that the cable is connected correctly.
In summary, the correct answers are:
The other options listed are not relevant to the troubleshooting of this particular issue. Option A, enabling SSH access on the Cisco IR829 router for IOx Guest OS, is not relevant to resolving RS232 data parsing issues. Option B, setting the communication mode to half duplex over the serial connection, is not necessary for this particular issue. Option C, restricting the cable length to 1.5 meters, is not relevant to resolving parsing issues.
