PROBLEM PROBABLE CAUSE AND SOLUTION
When Transferring the project to a MRC88, the transfer
stops with a "Transfer aborted-Receiver Stopped
Responding" or a "Communications Error---" message.
The following items may have interfered with the
transfer of data. Check each one in the order listed,
then redo the transfer.
a) Click on Preferences under the FILE menu and
verify proper Com Port is selected
b) Make sure no other software is running that also
requires the Com Port
c) Conduct a “Base Unit – Who Am I” to verify proper
communication with the MRC88.
d) Check the COM PORT interface cable for
continuity on each of its 9 leads. This is a Pin to
Pin, 1:1 configuration. Replace if necessary.
e) Your computer may have run out of system
resources (memory). Quit other open applications
and restart Windows with the MRC88 connect to
the PC
.
After transferring commands to the MRC88, it works fine
... except at certain times the MRC88 refuses to output
any commands at all.
IR noise may be on the IR bus-line coming from an IR
receiver in another room or rooms, preventing a clean
IR signal from arriving at the controlled component.
a) Temporarily disconnect each MRC88 Keypad one
at a time, until you find the one causing the
interference.
b) Look for sources of IR interference near the IR
receiver(s) [such as PLASMA, CFL lamps, TVs,
Neon lighting, etc.]. Move or shade the IR
receiver(s) or take other steps as necessary.
The STATUS LED under the POWER button on the
Keypad is never illuminated GREEN or flickers
constantly.
Again. IR noise is probably the problem. Adjust the
Input Sensitivity of the IR Receiver might be to
sensitive. Back off (turn CCW) on the IR Sensitivity
Adj. on the rear of the keypad until the GRENN LED
comes on steady. If a PLASMA is nearby, you might
need to disable the Keypad IR Receiver and add a
Plasma Friendly unit to the system.
