Dukane Manual Part No. 403–566–01
Section 5 – Rear Connectors
Table 5—V on the previous page lists the pinout
and signal description for J902 which is the Press
Base connection. Note that there is an automation
input on pin 8 which is electrically identical to
pin 8 on the System Input connector. This permits
you to use J902 to initiate operation without having
to run a separate connection to pin 8 of the System
Input connector. Figure 5–9 on the previous page,
identifies the pin numbers for both J902 and J901.
Table 5—VI below gives the pinout and signal
description for J901 which is the 36–pin Thruster
connector. This connector is the same type as found
on the DPC–III and DPC–IV. The cable specified
is Part No. 200–1104 which is interchangeable
with both DPC–III and DPC–IV generators.

NOTE
J902 Press Base connector has multiple ground pins.
The DPC–2 Plus/EZ uses pins 5, 6 & 7 for Ground.
The DPC–3 uses pins 5 & 7 for Ground.
The DPC–4 uses pins 6 & 7 for Ground.
To keep your custom automation circuits com-
patible with DPC models, only use pin 7 for a
ground connection to the Press Base connector.
It should be pointed out however, that the DPC–3
does have an Automation Input on pin 8.
