Monitor Window
Monitor Window displays the frames captured during monitoring in real time. Its key capabilities are listed below.
| Feature | Description |
|---|---|
| Channel tabs | Switch among up to eight channels, allowing you to review bus data for each MicroPeckerX connection. |
| Signal View / Dual View | • Signal View: Enlarges a single channel. • Dual View: Places two channels side by side for simultaneous comparison. |
| CAN bus load graph | Visualizes the traffic load (bus utilization) for each channel so you can grasp the situation at a glance. |
These functions let you monitor multiple buses simultaneously and keep track of the overall load in real time.

| Item | Description | |
|---|---|---|
| Baudrate | Configured baud rate. | |
| Total | Number of frames received without errors. | |
| Std. FD Frm. | Number of standard-ID CAN FD data frames received without errors. | |
| Ext. FD Frm. | Number of extended-ID CAN FD data frames received without errors. | |
| Std. Data Frm. | Number of standard-ID CAN data frames received without errors. | |
| Ext. Data Frm. | Number of extended-ID CAN data frames received without errors. | |
| Std. Remote Frm. | Number of standard-ID remote frames received without errors. | |
| Ext. Remote Frm. | Number of extended-ID remote frames received without errors. | |

| Average a Second | Bus load over the most recent second. | |
| Max | Maximum load observed during monitoring. | |
| Min | Minimum load observed during monitoring. | |
| Ave | Average load over the monitoring period. | |
※ Bus Traffic is calculated using the worst-case bit stuffing, so values may exceed 100%.
Single View / Dual View Switching
You can switch Monitor Window between Single View and Dual View while monitoring or when monitoring is stopped.
| View mode | Description |
