2.3.2 DC Unit J3 Connector Pinouts
Figure 2-7: DC Unit J3 Connector Pinout

Pin Name
A V-/Ground
B V+
C V+
D V-/Ground
For the DC input, the positive terminals are pins B/C and the negative terminals are pins A/D. Pins A and
D are connected to case ground internally; pins B and C are connected together internally. It is
recommended to apply the supply voltage evenly to both pairs of pins to evenly share the current among
both sets of wires/pins.
The internal capacitance between the V+ and V- terminals is approximately 120 microfarads.
2.4 J2 – Monitor and Control Interface
The M&C interface is used to control the unit with a host computer. All on-board sensors are accessed
through this interface. Use of this connection is optional. Each ATOM is supplied with a mating connector
for the M&C interface.
The 25-50W ATOM can be ordered with standard or Ethernet web interface options. Table 2-2 summarizes
the M&C interface protocols available with each option.
