Re: CB34EX JP23 / JP26 Description

Hello Tim,

That is correct. If you want termination on the DB9, they need to be added to the connector or cable.

Re: CB34EX JP23 / JP26 Description

Thanks Tim. The goal is bus impedance matching. A RS-485 bus is a multi-drop bus, meaning it can have more than one device on it. Whether just two devices or many more, only each end of the bus should have 120 ohm termination, and optionally bias resistors. The impedance matching reduces reflections...

Re: CB34EX JP23 / JP26 Description

Take a look at page 4 here, where Rb is bias, and Rt is termination:

This is not the part used on the CB34EX, but it has good graphics. The termination and bias in the CB34EX are all 120 ohms

Re: CB34EX JP23 / JP26 Description

Hello Tim, Before going into those details, can you tell me what you are connecting to, and if that device has options for termination or biasing? It will be easier to explain if you can describe what it is and how many devices are on your 485 bus, as these are bus terms and selections dependent on ...

Re: uCos task for polled I/O, reasonable speed expectations?

Hello, The issue you are running into is that a Real Time Operating System (RTOS) means "the highest priority task ready to run will run". It is not a time slice like you would have in linux or windows. There is an article here for 2.x tools users that may help: https://www.netburner.com/d...

Re: TLS or SSL level used with 2.9.5

Hello,

The default for 2.9.5 is TLS 1.2. The error message you indicate is negotiation failed, so it must be for some other reason. A wireshark trace might help. It might be a good idea to work directly with our SSL/TLS engineers with a support ticket.

Re: Using DHCP w Fallback

How long are you waiting for DHCP to fail? DHCP has a timeout period for retries to the server that is not directly related to link. For example, a situation could be that the Ethernet connection is through a managed switch which takes some time, or some other mechanism that where a link is not imme...

Re: MOD-5270 Refer Code Base ?

Hello, Minor correction. The MOD5270 is not supported in the 3.x tools. Use 2.9.5 instead. We will also be releasing a 2.9.6 by the end of the year. I am not clear on the path \NetBurner\Projects, or "refer". Can you please clarify? If you mean examples, they will be in the \nburn\examples...
