NXA-PDU-1508-8 Power Distribution Unit
NetLinx Programming
Device IDs
The NXA-PDU-1508-8 uses 8 AxLink device IDs, starting from the device ID denoted by the DIP switch:
Dev 1: Output 1 + AxLink Power 1 + Input Voltage + Temperature
Dev 2: Output 2 + AxLink Power 2
Dev 3-8: Outputs 3-8
Supported SEND_COMMANDs
SEND_COMMANDs
PERSIST Configures the designated power outlet to return to the last state on loss of power or reset of
the PDU.
By default, a shipping PDU shall have all power outlets PERSIST setting ON.
Syntax:
PERSIST-<outlet #>=<value>
Variables:
• <value> may be ON or OFF
• <outlet#> 1-8 for AC outlets, 9 and 10 for AxLink 1 and 2 bus power, respectively.
Note: As there are limited write cycles to the storage of the persistent data, setting an outlet
to PERSIST ON should only be used when absolutely necessary, and never for very
frequent toggling operations.
?PERSIST Queries the PERSIST state of all outlets.
Returns a comma-delimited list in the form:
PERSIST-1=<value>,2=<value>,3=<value>,4=<value>,5=<value>,
6=<value>,7=<value>,8=<value>,9=<value>,10=<value>
<value> will be 1 for ON or 0 for OFF, (e.g.):
PERSIST-1=1,2=0,3=0,4=0,5=0,6=0,7=0,8=0,9=1,10=0
?PHASEANGLE Syntax:
?PHASEANGLE-<outlet #>
Responds with:
PHASEANGLE-<outlet #>=<Phase Angle>
Note: "Phase angle" is the difference in phase between Voltage and Current, useful for
determining inductive vs. capacitive loading.
RESET Syntax:
RESET
Triggers a Power-On-Reset of the PDU. A Power-On-Reset toggles all interruptible power
outlets.
?SERIAL Syntax:
?SERIAL
Retrieves the 16-byte serial number assigned to the PDU.
Responds with:
SERIAL <XXXXXXXXXXXXXXXX>
where <XXXXXXXXXXXXXXXX> is the 16-byte serial number assigned to the unit.
TRIGGER Syntax:
TRIGGER-<outlet #>=<Power Sense Trigger>
Sets the Power Sense Trigger of the specified outlet to the specified value in tenths of
Watts.
Note: A "Trigger" is a current level which will cause a power sense channel to activate if the
current exceeds the value.
