What is the upper limit of communication speed with which the PC link software can monitor without any loss or error?
It depends on the monitor condition of the analyzer, PC spec and the load condition, and the conneciton method between PC and the analyzer. Please see the following result for the reference.
●Outline of the test
Connecting LE-3500R with the PC link software "LE-PC300R" via Wi-Fi, USB, and serial(AUX) and investigated the upper limit of the speed of RS-485 communication(1KB data, full-duplex) with which the software can monitor without any loss for 10 minutes.
●The result of testing
- The data size of a frame transmitted on the line: 1KByte
- Other conditions: NRZI and HDLC are AR, without idle time.
| Protocol | Method | Connection | Error check (BCC/FCS) |
The upper limit |
|---|---|---|---|---|
| ASYNC | Full-duplex | Wi-Fi* | None | 200Kbps |
| LRC-Even | 200Kbps | |||
| USB2.0 | None | 2Mbps | ||
| LRC-Even | 2Mbps | |||
| AUX(115.2Kbps) | None | 24Kbps | ||
| LRC-Even | 24Kbps | |||
| HDLC | Wi-Fi* | None | 100Kbps | |
| FCS16 | 115.2Kbps | |||
| USB2.0 | None | 2Mbps | ||
| FCS16 | 2Mbps | |||
| AUX(115.2Kbps) | None | 19.2Kbps | ||
| FCS16 | 19.2Kbps |
*: The upper limit differs depending on the radio condition of Wi-Fi.
Theoretically the upper limit is higher when the condition is set to "without error chack".
