32 | CONNECTING YOUR INTERACTIVE WHITEBOARD TO YOUR COMPUTER
NOTES
The DB9 connector on the expansion module doesn’t have captive nuts
to enable you to secure the serial cable to it. A “post” feature on the
RS-232 expansion module routes the serial cable so that if something
pulls the cable, the force is perpendicular to the connector. If someone
accidentally trips or pulls the cable, the unsecured cable will disconnect,
preventing damage to the module’s connector or its pins.
When wall-mounting your interactive whiteboard, you can also route the
serial cable through the channel on the back of both the RS-232
expansion module and the controller module to prevent strain
on the cable.
4. Connect the power supply to the
expansion module. You can also route
the power cable through the same
channel as the RS-232 cable.
WARNING
Use only the power supply included
with the RS-232 serial expansion
module. Using other power supplies
might create a safety hazard or
damage the equipment. Although
your interactive whiteboard won’t be
damaged if you connect a power
supply with reversed polarity, a
computer or extender that you
connect to the USB interface might
be damaged.
5. Connect the other end of the serial cable
to a serial connector on your computer.
6. Connect the power cable to the power
supply, and then connect it to a suitable
AC power receptacle.
The Ready light turns red, indicating
that your interactive whiteboard
is receiving power.
