Re: SBL2eX Custom Packetization Anomaly

Thank you for your reply. We switched to using "Number of characters to accumulate before sending TCP/UDP packet" packetization option for other reasons. In the process, we found that the "Number of milliseconds to wait for accumulated characters (0 waits forever)" option did not...

Re: SBL2eX Custom Packetization Anomaly

Tom, Thanks for your reply. We are using UDP and the network is a simple isolated network, so there is little chance of other devices impacting this, I think. We are using Wireshark to sniff the interface (using a passive tap) directly on the SBL2eX device. The Wireshark trace is how we noticed the ...

SBL2eX Custom Packetization Anomaly

We have an SBL2eX set up to use custom packetization using the option for "Number of milliseconds to wait for accumulated characters" set to 60. We have a serial device sending blocks of 18 characters every 20 ms. Looking at the IP packets generated by the SBL2eX, there is a timing anomaly...

Re: Receive only SBL2eX

We tried it out. I can confirm that blanking the destination IP address and port number causes the device to stop sending IP packets. Receive functionality was unaffected.

Re: Receive only SBL2eX

Thanks for your reply. This is in a lab environment. Single use to enable a specific test. At the moment, we are using a standard cable, so it's not easy to disconnect the TX data line. We can try using some unused address or port. What would the SBL2eX do if we blank out the sending address or port...

Receive only SBL2eX

I have an SBL2eX-100IR. I want it to use it in UDP mode to only receive packets, i.e. only go from UDP -> serial. I don't want it to send any UDP packets regardless of what it sees on the serial port. If I do not load any outgoing address or port number in the settings, will that have the intended e...
