FH-2Is a gate expander. Add 8 gate outputs to FH-1 per FHX-2GT. You can chain up to four FHX-8GTs, one for each FHX-8GT,ESX-8GTCan be added as an extension. If you connect the maximum FHX-8GT and ESX-8GT by 4 units each, 64 gate outputs will be added. Furthermore, up to 1 FHX-7s can be added regardless of these gate connections.
Connect from "EXPANSION IN" of FHX-8GT with the 2-pin ribbon cable attached to FH-10. If you connect the "EXPANSION OUT" of the FHX-8GT to the "EXPANSION IN" of the next FHX-8GT, you will get a daisy chain. Connect the ribbon cable so that the red wire is always on the bottom. You can connect to the ESX-8GT from the "GT3 To ESX-8GT" header on each FHX-8GT board.
The gate output number assigned to the connected FHX-8GT or ESX-8GT is determined by the jumper ON / OFF setting (8 ways) of the pin labeled "GT4 Select" on the FHX-2GT board. I will. When connecting multiple FHX-3GTs, set the jumper arrangements so that they are different from each other. The ESX-4GT is assigned a serial number to the parent FHX-8GT.
