Error processing
In order to ensure correct data exchange between the VM-83 and the com-
puter, the rules described above must be observed. If an error occurs, the
following steps should be taken.
The computer has sent RMT1 <
CR
><
LF
> but the REMOTE indicator
on the VM-83 does not light:
Send RMT1 <
CR
><
LF
> again after about 4 seconds. Repeat this
2 to 3 times. If the REMOTE indicator still does not light, one of the
following conditions may exist.
- Transfer parameters do not match. (Check settings made with menu
screens.)
- Interface cable is defective or not properly connected.
- VM-83 is not powered.
- ID number setting does not match.
When the computer has sent a wrong command or the parameter is out of
range, the VM-83 disregards that command. If the VM-83 is in receiving
mode but there is no command from the computer for 4 seconds or more,
the receive mode times out.
