We are not familiar with such issue.
Which firmware version is installed on UniStream?
Did you try to cycle power the Unistream.
If after power cycle it still cannot connect then send a mail to firstname.lastname@example.org with the application and we will try to test it here.
I have a few questions:
* When you say it is connected to Port 2 of the V570 - do you mean COM2? Does the thermocouple have a Serial/Modbus interface?
* The post by Flex727 is correct, the E2B snap-in module doesn't take thermocouple inputs directly. It would need a signal transmitter, typically this converts the thermocouple interface to 4...20mA current signal.
If you have a datasheet for the thermocouple and/or any photos of the device and the way youhave it wired up, please post.
