Battery Replacement
A Lithium battery is used to power the system clock within the QM-RMC.
Under normal conditions, it lasts for approximately 10 years. In the event that
the clock fails, only an authorized technician should replace it. Refer to the
following caution statement.
CAUTION: Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's
instructions.
Passthrough Mode
Passthrough mode enables Viewport access to any serially controlled device on
the network. That is, it allows direct communication between the PC and a
network device (effectively "passing through" the QM-RMC). While
Passthrough mode is running, the program currently in memory is suspended
and will not execute. When Passthrough mode is exited, the program resumes
operation.
Entering Passthrough mode for COM port B reinitializes it, which clears the
data for that port.
To establish communication, click Functions | Enter Passthrough Mode. Then
select the connection type that exists between the QM-RMC and the device. The
