MDR-2000

User's Reference Manual
Troubleshooting
its protocol with the downstream processing facility which may inadvertently have these character
values.
With this background,
if
communications with the PBX
is
problematic or there are difficulties
downloading data the following should be reviewed:
• Make sure a cable connections are secure, and that the cables are the correct type. The cable
from the MDR-2000 to the PC must be a 'direct' cable, the cable from the MDR-2000 to a
modem must be a 'null modem' cable (the null modem cable is usually provided).
• Make sure
PBX
is generating output. Often the cable to the PBX is not installed correctly or the
serial port
on
the PBX is disabled.
• Make sure communications port settings are correct. The default in the MDR-2000
is
1200
Baud, 8 data bits, no parity.
• Make sure communications link with downstream processing facility
is
data transparent.
Disable any flow control or handshaking that might be in place.
•
If
the MDR-2000 is responding to commands from a terminal program, but is not collecting
data from the PBX, use the '
DU'
command which will cause any data received from the PBX to
be dumped, unedited, on the terminal. This will confirm that the data flow
is
setup correctly,
and the problem is a record formatting problem.
6.2 Physical Examination
When examining the MDR-2000 physically the first step
is
to ensure that all cables and power
cords are properly secured.
On the modem the terminal ready indicator and the modem clear indicator should be on. On the
MDR-2000 itself, LED RUN (CR9) should be on.
If
it is not, and no other LED's are on, then the
MDR-2000 is totally inoperable. Check
to
ensure that power has been applied to the MDR-2000.
IfLED
RUN is on, and LED BMT (CR6) is on then the unit is operating and there are no call
records stored in the
unit. When LED BMT is extinguished the unit is properly collecting calls. On
new installations it is sometimes a problem to get proper call recording established due to variances
in the PBX record format. LED BMT
is
the key to determining when the problem
is
resolved.
