The electronics chassis was brought into the lab today (thanks Phil and Dave) and we began testing the integration of the optomechanics with the CDS. An ethernet cable was run into the JOAT CHETA lab to connect to the server.  A variable power supply was brought into the lab to power the chassis at the required 24V along with a linear power supply required for the rotation stage and translation stages. 
The flipper I/O input and output had to be configured for Beckhoff communications using this guide.
The current status of our testing is as follows:
Working:

• Flipper
• PD
• Power meter

Not working:

• Rotation mount 

Untested:

• Translation stage

We have realised during this process that the flipper isn't powered by the SMA connectors and requires a seperate power source. This was not considered in the initial panel design and is not currently supplied by the chassis. There is a spare blank connector input/output slot which can be used. 

We have begun making the medm display for the CHETA system based on the current CO2 medm which shares many optomechanical systems. CHETA isn't currently on the TCS screen so to run the medm display currently the following command must be run to access the work in progress. 

medm -x -macro 'USERAPPS=/opt/rtcds/userapps/release/,SITE=LHO,site=lho,IFO=H1,ifo=h1,OPTIC=X,OPTICF=ITMX,name=AWCITMX,RT_MEDM=/opt/rtcds/lho/h1/medm' TCS_CHETA.adl 

To open the medm in a configurable format:
 medm TCS_CHETA.adl 
Alternatively to edit the code files:
code medm TCS_CHETA.adl 

Further alignment on the ITMY table was completed with almost all optics now mounted on the table.
