how to solve "No registered trigger lines could be found between the devices in the route"

[Reinhard]

Hi, everyone. I have a problem when I finally connected all the device for my in-vitro system. When I click "start" in the NeuroRighter, the pop-up warned my "No registered trigger lines could be found between the devices in the route". The picture is shown below. We used a testing chip, a preamplifier and a filter amplifier form MCS. Then they are connect to the in-vitro interface board. The board are connected with four SCB-68A connectors with ribbon cable. And the connectors are linked to PCIe card in the PC. The possible reason could be the RS232 cable in the preamplifer. Because our PC doesn't have a RS232 connector, we used a adapter to convert RS232 to USB for the connection between PC and the preamplifier. 

Another problem is that I'm not sure whether the RS232 cable is needed? Because it seems to be used to control the MEA chip with MCS's own software.

Did somebody meet the same problems? And some suggestions?

Yeah, as Riley states, you either:

- Have not properly configured hardware with the RTSI bus

 or

- Have not selected the correct DAQ cards in the System --> Neural Input tab

I think this amplifier has built in stimulation circuity, which is what the RS232 connector is for. This  will do nothing for you with stock NR (unless you want to write some code). Instead, we use custom _all channel_ stimulators which allow real-time switching between any electrode in the dish. Look at the bottom of this page

which are much better than the MCS option. In fact, our friend Andrew at Nonlinear circuits (CCed) just designed a new stimulation PCB that simplifies this process quite a lot.

Hi, Jon,

Thank you so much! I will check the hardware configuration again.
