Section 5 – Rear Connectors
Multi–Point Master Module
Part No. 110–3954
This optional module enables the DPC II to
activate any one of four ultrasonic probes. Each
probe is selected by the Probe ID# (pins 12, 13
& 14) of the HD–15 System Input connector
(see Table 5—II). Rear panel bicolor LED status
indicators for each probe output illuminate green
when the probe channel is selected and red when
the U/S is active. The Multi–Point module is only
compatible with the Rev–1 DPC II motherboard.
Both a MPC Master and Slave module are shown
below in Figure 5–14.
Internal logic prevents more than one probe from
being activated at a time or probe switching signals
when the U/S is on. A ring-down circuit permits
switching only when U/S output is zero. Internal
fault logic senses any malfunction and deactivates
the MPC Ready output. The Multi–Point Controller
cannot be used with a press module. The master
module has an extra wide back panel to prevent
it’s accidental use with the press module.

Part No. 110–3956
This optional module adds four additional probe
selection channels to the DPC II. This gives a
total of eight probe channels. The slave module
cannot be used alone. It must be used with the
master module. An internal connector supplies
the ultrasound signal from the Master module. As
with the Master module, each output channel has
a bicolor LED status indicator that illuminates
green when the probe channel is selected and red
when the U/S is active.
NOTE 1
External automation
can be used to select
the probe. In a DPC
II system, the exter-
nal automation also
controls the weld and
hold times.
NOTE 2
The Ultrasound in-
put on the MPC
Master must be con-
nected to the DPC
Ultrasound output
connector with a
RG62B/U coax. This
is indicated as Cable
2 in Figure 3–6 (Part
No. 200–479–01).
