Adapter Services#
Display 
The adapter uses the display if the target device is not utilizing it. The display shows information such as the firmware version, network configuration, nickname, debug mode, and serial number.
UDP Discovery
The adapter includes a UDP discovery service that listens for packets on port 4920. When the adapter receives a specific message, it responds with identifying information, making it discoverable when connected over Ethernet.
Scratchpad 
The Scratchpad is a 16 KB text file stored in the adapter's file system. You can read from or write to it using the Admin Console.
Logic Analyzer
The logic analyzer has eight channels and samples at a rate of 100 kHz. It has four internal connections and connects to a header with four external connections. The internal connections are connected to the two user LEDs and the two user buttons. You can use the logic analyzer to correlate software or hardware events with AEM and PTI data. However, due to its low sampling rate, it is not suitable for protocol decoding.
Because the sample rate of the logic analyzer is 100 kHz, the minimum signal length that can be detected is 10 μs for most channels. Channels 6 and 7, which are connected to buttons, have an additional 3 μs delay due to hardware differences. Therefore, the minimum signal length that can be detected for these channels is 13 μs.
For more details, see the logic analyzer data packet structure.
The channels of the logic analyzer are connected to different features as follows:
Type | Channel | Description |
|---|---|---|
External signal | 0 | Connector (ch0) |
1 | Connector (ch1) | |
2 | Connector (ch2) | |
3 | Connector (ch3) | |
Internal signal | 4 | LED0 |
5 | LED1 | |
6 | BTN0 | |
7 | BTN1 |
Time Synchronization
The adapter includes a time synchronization service that can synchronize the clocks of multiple adapters on different kits. One adapter acts as the server, while the others operate as clients. For communication between adapters, the service operates over UDP and uses port 4904 by default.
Clients synchronize their clocks to match the server's. The accuracy of synchronization depends on network factors, such as whether the adapters are connected to the same network switch. In ideal conditions, synchronization accuracy should be within 10–100 μs after 10 seconds of connecting to the server.
You can enable this service using the Admin Console.
