Tech Note 103 Accelerometer Powering
with CCD Diode
When connecting a
CMCP525/530 Transmitter to a Accelerometer that is already powered by another
device the CCD (Constant Current Diode) should be cut to prevent overpowering of
the Accelerometer by connection to both devices.
Simply cut one end of the CCD loose from the circuit board with a small pair of
wire cutters. Lift slightly and place a small piece of heat shrink over the CCD
to prevent it from touching. The CCD can then be reattached, if required, using
a soldering iron.
When using a CMCP525/530 in a Dual Path configuration with the CMCP/CMSS590
Enveloping Transmitter it is not necessary to cut the CCD as the CMCP/CMSS590
has a jumper for disabling CCD power. Simply power with the CMCP525/530 and
disable power in the CMCP/CMSS590.
