4.8. Building a DSC Cable for Direct Servo Control
A DSC cable will allow you to control servos directly if you are using a PCM receiver,
and with any receiver you will be able to read the receiver battery voltage directly on the
9Z's LCD display, this can be very useful!
First, you should refer to APPENDIX B for information on the Pin-out numbering. Then,
to make your own DSC connector cable, you need to:
1.
Purchase a standard 6 PIN DIN connector for plugging into the transmitter (available
through audio or electronic component suppliers)
2.
Purchase a servo connector for plugging into the receiver.
3.
Connect the DSC control line (servo white wire) to the signal output line of the
transmitter (DIN Pin 2).
4.
Connect the receiver ground (servo black wire) to the ground of the transmitter (DIN
Pin 0).
5.
Connect the receiver voltage (servo red wire) to the +5v Input of the transmitter (DIN
Pin 6).
6.
Last, you need to jumper the transmitter battery to the switched power circuit. (DIN
Pin 4 to DIN Pin 5).
4.9. DIY CAMPAC's and "backing up" model memory to a PC
CAMPACs allow you to add additional model memory to your 9Z. The original Futaba
CAMPACs are insanely expensive so there are a number of CAMPAC clones that have
sprung up. You can either make one yourself or buy one from an aftermarket supplier.
CAMPACs come in different sizes – 16K, 64K, 128K and 256K. Unfortunately only 64K
and larger CAMPACs will work with the 9Z. This is annoying as the only simple-to-make
