ACQ-7700 Connections
The standard ACQ-7700 has two input/output connectors on the front panel of the
EPP interface board: The EPP Port connector and the AUX connector. The EPP
acquisition board is installed in the first slot from the left on the front of the ACQ-
7700.
EPP Port Connection
This parallel port connector is a 25 pin D-shell male connector. A standard 25 pin
male D-shell to 25 pin female D-shell parallel port cable (P01255) is connected
between the EPP Port connector on the case and the parallel port on your computer.
The parallel port cable must be connected before the ACQ-7700 and computer are
turned on. The ACQ-7700 must be powered ON before starting the P3 Plus
software.
This 25-pin D-SUB provides connection to the PC.
