Two voltage sourcing analog outputs are provided on the System Base. The output voltage from
these outputs is under software control via the Program Net.

ONNECTIONS
Connections for these two analog outputs, identified as AO_A and AO_B are on the bottom
terminal strip, terminal pairs 17 and 18 (AO_A) and 15 and 16 (AO_B).

HARACTERISTICS
The analog outputs’ voltage range is from 0 to 10Vdc assuming a supply voltage greater than
~10.5Vdc is connected. The output is current limited to ~30mA and can be shorted indefinitely
without damage. The 10Vdc is sourced from the unregulated supply voltage. For a full swing
to 10Vdc, the voltage powering the IntelliLogger must be approximately 10.5Vdc or greater. In
the event that the supply voltage drops below 10.5Vdc, the analog output maximum voltage
will be reduced correspondingly.

OMMUNICATION
C
ONNECTIONS
On the bottom end of the IntelliLogger are a variety of communication connectors for RS-232,
USB, Ethernet and BBus communications. These connectors are provided for communication
between a PC and the IntelliLogger, for network connection, for connection to Interface Modules
and for hook-up of external communication equipment such as modems
Note:
The BBus and Ethernet ports both use the same RJ-45 type
connector so always double-check that cables for either
communication are plugged into the correct connector!
RS-232 (PC)
The DB-9 Female connector on the right end is dedicated to direct connection and
communication with a PC RS-232 serial port. It does not have the full suite of control signals
implemented.
RS-232 (C
OMM
)
The DB-9 Male connector supports all of the signals for RS-232 communication. This port is
dedicated for connection to external communication devices such as modems and RF
transceivers. Contact Logic Beach for the latest offering of supported devices.
USB
A single USB 1.0 compliant port is provided. This ‘Type B’ port is for direct connection via
USB cable to a USB port on a PC.
