CTCSS Decoder
Connect the TS-64 CTCSS Encoder/Decoder assembly to the CAT-200B as described in Figure 6-5. The
decoder must be connected to discriminator audio. Speaker or volume control audio will have insufficient
low frequency CTCSS tone content.

Connector Kit
The connector kit contains a DB25 male connector with hood, a 2.5 mm DC power plug, two 2200-ohm
pull-up resistors and two .0047uF capacitors. If the CAT-200B is supplied with discriminator audio,
install the .0047uF capacitor on the board at position C10 or C11 in the case of the link receiver. If
required install the 2200 ohm resistors on the CAT-200B board to pull-up the COR inputs.
