We installed a Beckhoff analog input module and uplink in the optics lab to monitor the RefCav transmission photo diode.  This temporary setup has an Ethernet cable from the optic lab to the MSR plugged directly into the Beckhoff Front End computer.  The photo diode signal it split off the BNC and converted to twisted pair and plugged into the beckhoff 3102 module.  At some point I need to extend this Cat5 cable to clean up the installation but the signal can be seen in the beckhoff system.
