CHAPTER 2
12. While holding the RMS communications module in
place, lay the unit on its side and secure the RMS
communications module using the four screws
provided with the kit.
13. Connect the 26-pin connector from the long ribbon
cable to the RMS communications module connector.
Make sure to fully lock the connector.
14. Using an ohmmeter, check the resistance across R13
on the RMS communications module. R13 is located
1 inch to the right of the center of the module. The
resistance must measure less than 10 ohms. If it
measures 47 ohms, remove the RMS communications
module (it is insufficiently grounded), return to step
6 and repeat, or contact Meyer Sound Technical
Support for assistance.
TIP:
Insufficient grounding could be the
result of over-thinning the back right screw
hole (see Step 7). If this is the case, using a shorter
screw may fix the problem.
NOTE: The resistance reading in step 14
presumes that the ribbon power cable has
been connected (step 11). If it is not connected,
return to step 11 and connect it.
15. Replace the AC input cable on the user panel to the
AC mains board and replace the signal cable to the
input board on the user panel, making sure to lock the
gray connector.
