This little board was recently redesigned to increase number of analog inputs, and to make it better fit on standard 12-pin 0.1" spacing header. It is a scanner of up to 32 contacts and 3 potentiometers. It usually finds its place in pedals of organ consoles. The board shown above has 12-way female socket for diode matrix needed to connect contacts. 5 pads on the right are for potentiometers and 4-pin connector for master controller.
As a standard it comes with 1.5m (5ft) cable to master controller. It is highly recommended to install this board at the pedals, so only inter-board cable is lead from the floor to upper console. The cable to potentiometers must also be short, preferably no more than 30cm.
As any other scanner board, this one cannot work just by itself, but it needs one of the master controllers to operate.
- scans 32 contacts in 4x8 diode matrix
- scans 3 potentiometer or external voltages
- user defined update rate and resolution of the pot inputs
- user selected 4 different diode matrix layouts
- usable with
- includes cable to master controller
- dimensions of PCB: 34x18mm (1.35'' x 0.7'')
Here is an example of diode matrix needed for PDS to work properly by default (other layouts are also possible):
The picture below shows how new PDS nicely fits the REED32
contact board for pedals. Overal height including cable plug is about 1".
