Appendix E: Trouble-Shooting
Here is a list of things to try to quickly fix any difficulties getting the BASIC Stamp
Editor to communicate with the BASIC Stamp:
If you are using a BASIC Stamp and Board of Education, also check the following:
If your Identification Window looks similar to Figure E-1, it means that the BASIC
Stamp Editor cannot find your BASIC Stamp on any COM port. Note that the Loopback
and Echo columns show “No.” If you have this problem, try the following:

If you are using a Board of Education Rev C, make sure the power switch is set
to position-1.
Rule out dead batteries and incorrect or malfunctioning power supplies by using
a new 9 V battery.
Make sure the serial cable is firmly connected to both the computer’s COM port
and the DB9 connector on the Board of Education or BASIC Stamp HomeWork
Board.
Make sure that your serial cable is a normal serial cable. DO NOT USE A
NULL MODEM CABLE. Most null modem cables are labeled NULL or Null
Modem; visually inspect the cable for any such labeling. If you find that label,
do not try to use it to program the BASIC Stamp.
Disable any palmtop communication software.
Make sure the BASIC Stamp was inserted into the socket right-side-up, aligning
the reference notch as shown in Figure 1-28 on page 17.
If you are using a DC power supply that plugs into the wall, make sure it is
plugged in to both the wall and the Board of Education. Verify that the green
Pwr light on the Board of Education emits light when the DC supply is plugged
in.
Make sure the BASIC Stamp is firmly inserted into the socket. Visually inspect
the BASIC Stamp to make sure that none of the pins folded under the module
instead of sinking into their sockets on the Board of Education. Disconnect
power first, then press down firmly on the module with your thumb.
