QM-RMC 
Purpose 
The purpose of this addendum is to provide additional information not supplied with 
the original QM-RMC Operations Guide (Doc. 6161). Specifically, this addendum 
corrects the procedure for establishing the serial console connection with Viewport 
using the SW-R button. This procedure appeared on page 11. 
Correction to “Establishing Communication with the 
QM-RMC” 
NOTE: Changes to the existing text are in bold as follows. The notes and image 
following the text are new. 
Serial console connection may be established only if SW-R button is pressed and 
held about 5 to 7 seconds during power up (wait for Viewport to display some 
information), or if pressed and held at the same time HW-R is momentarily pressed. 
NOTE: The COM B LED will flash when in the console mode. 
Example of Viewport Message – No Program Loaded
