AE-C2
The AE-C2 contains 5x DB9F, 1x DB25F and 1x DB37F connectors. The four left hand DB9s are
from bottom to top, Port 1 to 4. Ports 1 to 3 are for surfaces and Port 4 is for PC control. The DB9
on the right is for External Sync, the DB25 is for GPI outputs and the DB37 is for GPI outputs and
inputs. All DB connectors are female and require male plugs.
Ports 1 and 2 use straight through DB9 connections from the Audio Engine to
the Surface. Port 3 swaps pins 3 and 8 on the engine side.
