11. Appendix B – Troubleshooting & Tips
Problem Reason/Solution
ISDEMO doesn’t work /
can’t connect to IS-900
Most common reasons (not in any order):
1) Connected to wrong COM port plug on the back of the
computer.
2) The selected serial port is captured by another program
and can’t be opened by ISDEMO.
3) The RS-232 cable running from the PCTracker Hub to
the computer is not a null modem serial cable (crossed
TX and RX lines).
4) The RS-232 cable running from the IS-900 to the
computer is not a straight-through serial cable.
5) Not using Start Displaying Data (CTRL-D). It may be
necessary to select Stop Displaying Data (CTRL-X)
first.
6) Check the communication settings for proper
configuration with either Serial or Ethernet, depending
on the choice of host communications.
7) If connecting over Ethernet, you may need to save the
settings and power-cycle the IS-900 for them to take
effect. Also, verify that you are using a patch cable if
connected to a hub/switch or a crossover cable if
connected directly to a PC.
8) If connecting over Ethernet, ensure that you are on the
correct subnet. This means that the first three dotted
numbers are the same between the PC and IS-900, and
the subnet mask for the PC’s network card is
255.255.255.0.
ISDEMO is running, but
system does not track
Check for the following:
1) The IS-900 is not plugged in or the host connection is
not plugged in or configured properly. Check all power,
connections and Communication configuration in
ISDEMO.
2) The SoniStrips are not connected to, or detected by, the
IS-900 (the port they are connected to should have a
corresponding red LED lit to indicate they are
connected – if no red LED is lit, then try powering down
the IS-900, unplugging and replugging the cable, and
turning the IS-900 on again).
3) The SoniStrips may be connected to the processor with
an incorrect cable. The cables used between
SoniStrips and between a SoniStrip and the IS-900
should have 10 pins, and will typically have a blue band
around them. If your cable has 8 pins, it is a tracker
cable and cannot be used with SoniStrips.
