Example 1: Two Pools in Binary Mode
To control the up converter presets using Pool A (Up_CtrlA set to GPI-A) and the output mode setting
using Pool B (Out-mode-Ctrl set to GPI-B), with both pools working in priority mode, the GPIs have to be
set up as follows:
•
Set GPI_A-Mode to Prio
•
Set Contact_1 to GPI_A
•
Set Contact_2 to GPI_A
•
Set Contact_3 to GPI_A
•
Set Contact_4 to GPI_A
•
Set GPI_B-Mode to Prio
•
Set Contact_5 to GPI_B
Pool A now consists of GPI 1, GPI 2, GPI 3 and GPI 4 in priority mode, controlling the Up converter preset.
Pool B consists only of GPI 5 (also in priority mode), controlling the Output mode setting.
Pool A now works as follows:
