Crestron CNXAO-8 CNX Analog Output Expansion Card
CNX Analog Output Expansion
Card: CNXAO-8
Description
Functional Description
The CNXAO-8 Analog Output Expansion Card provides eight analog output
connections with a maximum voltage span of +/-12 VDC and 80 mA maximum
source/sink current. The analog output connections are arranged as two groups of
four with a multi-turn span adjustment for each group. Each group has a jumper (X1
and X2) to select whether the outputs power up/reset at 0% or 50%. Furthermore,
each output has a multi-turn offset potentiometer (pot) to position span as required.
Physical Description
The CNXAO-8, shown below, is a circuit board fastened to an aluminum faceplate.
The card is manufactured to easily fit into an unoccupied slot in a Crestron CNX
Generation Control System.
CNXAO-8 Faceplate
The faceplate contains two identical 5-position mini-Phoenix type connectors
(labeled A and B). There are four analog output pins and one common ground pin
per connector. Silk screening is applied to the faceplate; pins are labeled A1 through
A4 and B1 through B4. Common ground pins are labeled with a G. All pots are
accessible from outside the CNX Generation Control System through holes in the
faceplate.

Setup
As of the date of manufacture, the unit has been tested and found to comply with
specifications for CE marking.
NOTE: This card complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Power Up/Reset Voltage Adjustment
The setting of two 3-pin jumpers on the CNXAO-8 card determines whether the
card’s output voltage is equal to the lowest value of the assigned voltage span (0%)
or the midpoint of the voltage span (50%) when the system is powered up or reset.
Two jumpers (X1 and X2) are required to provide adjustment to two output groups
(A and B), respectively.
CAUTION: Besides setting the jumper, initialize values in the SIMPL Windows
program so that the device receiving the analog signal does not exhibit drastic
voltage swings upon start up or reset. Failure to do so may result in damage to the
device being controlled.
