10-pin IDC headers are for linking multiple single or dual testers so only one power supply is needed
pin1,2 0v
pin 3,4 link pin 6 of edge connector
pin 5,6 +16v
pin 7,8 -16v
pin 9,10 +48v
14-pin IDC headers on the dual tester. The first 12 pins are half of Tascam DB25 pinout.
So 2 dual testers and be used to fit 500 modules into mixing console etc and easily ribbon cable out to D25 patchbays
Since all in and outs and power are on the 10 pin and 14 pin IDC connectors the XLRs and XLR front panel can be left off making the depth shorter for mounting inside non 500 consoles
pin 1 0v
pin 2 -in left channel
pin 3 +in left channel
pin4 0v
pin 5 -out left channel
pin 6 +out left channel
pin 7 0v
pin 8 -in right channel
pin 9 +in right channel
pin 10 0v
pin 11 -out right channel
pin 12 +out right channel
pin 13.14 0v not normally used
