 ) Check that your SNAP modules are snaped into the system. Idealy they should be connected and configured but they are most probably not.
-) Check connectivity with the Brain by opening the command prompt (Start->run->cmd) and pinging the brain (e.g. "ping OPTO2"). If you can't ping the brain, check that you are on the same subnet (see [[Finding your IP address]]) by verifyng that the first three bytes of the IP Address of the lab computer you use to interact with the opto brains are the same as the Opto ones. Your brains IP addresses should be 137.215.116.xxx. If this doesn't work contact your Network Administrator (IT Help Service) on the extention numbers 3051 or 4845.

 To ping a brain, one must proceed as follows: click Start->run->cmd-> a black window prompt appears-> then type the comands:ping brainIP press Enter. (eg:for Opto1. >>ping 137.215.116.239 press Enter). If a message reading "Reply from 137.215.116.239:" appears, then the brain is responding to communication. If the message reads "Request timed out", then the brain does not respond and the network administrator should be contacted.

 ) Configure the SNAP modules. Run Start->All Programs->Opto 22->SNAP Ethernet IO Configurator. see one of the existing configuration files as an example. I have found that the configuration fails in some cases if you don't configure all the attached SNAP modules, the workaround here is to pull out everyone else's SNAP modules. Ideally all the SNAPs should be connected and there should be one master configuration file for each Opto brain and then you are only responsible for setting up the scaling in the file. I cannot figure out how the scaling works, if you figure it out please document it here. I used default scaling and converted the mA signal to engineering units in my application.

 Opto provides a C API to code your own Opto interface applications. Included with this is an example application (\\freki\C$:\Opto22\OptoENET-IO\DriverToolkit\Examples\C++\VC6\Eiocon\Release\eiocon.exe) that you can use to easily test communication with the brain and easily writing manual data to the rig. Run the application from the command prompt with the Opto brain's ip as an argument (Start->run->cmd)
