The APOX Kit FAQ's

Please be patient! (This FAQ is brand new and not very informative yet!)

How does the APOX system work?

The APOX currently has three boards: The front panel board(The APOX-IS1)is the main user interface board, this board also functions as the master controller for all other boards. It accepts optical encoder inputs, push buttons, and infrared remote control input. All other slave boards are controlled via I2C. All external boards will have a small PIC microcontroller on it. They will accept the addressed I2C command.
The APOX-IS1 is a full passive input select board using relays.
Then there are three different version od the Volume Control Boards. The APOX-1, APOX-2, and APOX-3. (see below for differences.)

What are the board sizes?

APOX-IR1 Front Panel Display Board: 9.35"x 1.8" (237.5mm x 45.7mm)
Apox1 Volume Controller: 3.2" x 6.9"
APOX-IS1 Input Select Board: 2.75" X 6.4"
Apox2 Volume Controller: 3.2" X 8.55"

What the difference between APOX-1,APOX-2, and APOX-3?

The APOX-1 is a shunt mode resistance ladder with 1020 different positions and mute, but the input impedance changes as you change volume settings. This is actually not a problem for most system. Tube People may want to consider the APOX-2
The APOX-2 is a series attenuator which has 23 taps and a mute but has constant input impedance. The APOX-3 is based on the PGA2310 (But has not been released yet.)

Can I program the boards myself?

Sure you can. We supply all source code for all of the boards. We use the CCS C compiler (www.ccsinfo.com) We also recommend Microchips ICD2 for debugging and downloading to flash.
