Preparing Captive Wires 1. Strip 0.25 inch (6.35 mm) of wire insulation off all wires. 2. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section. 3. Turn the flat-head screws clockwise to secure the wires in the connector. AxLink Data and Power Connections Connect the AxLink device’s AxLink connector to one of the AxLink connectors (1-8) on the rear panel of the PDU for data and 12 VDC power as shown in FIG. 9. AxLink Wiring Guidelines AxLink devices require 12 VDC power to operate properly. The necessary power is supplied via the AxLink cable. The maximum AxLink wiring distance is determined by power consumption, supplied voltage, and the wire gauge used for the cable. Use the 3-step formula below to calculate the maximum wiring lengths allowable between the PDU and connected AxLink devices. 1. < Total current consumption of all connected AxLink devices > x < Resistance/Foot > x 2 = < voltage drop per foot > (see table below for Resistance/Foot values.) 2. < Power supply voltage > - 12 VDC = < surplus voltage dissipation for cable run >. 3. / < voltage drop per foot > = Maximum distance in feet. The following table lists the resistance factors used in the formula. Do not over-torque the screws; doing so can bend the seating pins and damage the connector.

CONFIG DIP Switch The NXA-PDU-1508-8 uses an 8-position DIP Switch (labelled “CONFIG”) to specify a unique device address for itself in a NetLinx Control System (FIG. 10). Setting the Device Address of the PDU The NXA-PDU-1508-8 firmware implements 8 AxLink device IDs, starting from the device ID denoted by the DIP switch. The device IDs used by the NXA-PDU-1508-8 are as follows: Dev 1: (Power Outlet 1) + (AxLink-Bank 1 Power) + (Input Voltage) + (Temp) Dev 2: (Power Outlet 2) + (AxLink-Bank 2 Power) Dev 3-8: (Power Outlets 3-8) To set the Device Address: 1. If connected, disconnect the power supply. 2. Set the CONFIG DIP switch according to the values shown below: The device number is set by the total value of DIP switch positions that are in the ON position. Note that the ON position is indicated on the DIP Switch. If you later change the device number, remove and reconnect the power connector to enter the new device number into memory. Power Outlets 1-8 The eight 100-240VAC 50/60 Hz, IEC C-13, 10A AC Power Outlet Connectors provide AC power to connected devices (FIG. 11). The PDU measures current use of each individual power outlet, including the two AxLink power outputs, with an accuracy of 0.1A. The PDU also reports the total current use of the entire unit.

Power Inlet The IEC C-14, 10A Power Inlet Connector provides 100-240VAC, 50/60Hz mains power to the PDU (FIG. 11). The PDU measures the main input voltage with an accuracy of 1VAC The Power Inlet Connector is equipped with a safety fuse (10A @ 240VAC) Powering On the NXA-PDU-1508-8 When power is applied to the PDU for the first time, the outlets are powered in sequence (1-8), with a delay of 0.5 second between outlets. The factory default state of all outlets upon initial power-up is ON. By default, Persistence for all outlets is set to ON. Persistence can be turned off via the PERSIST SEND_COMMAND (see page 11). For subsequent power-ups (from a power off state or on system reset), the PDU will restore the last recorded state of any outlet in a sequenced fashion, starting from outlet 1 in numerical order, with a delay of 0.5 second between energizing any two outlets, assuming the default Persistence setting of ON has not been changed via the PERSIST command. When replacing the fuse, use only a 10A 240V Slo-Blo fuse Since the number of write cycles to the storage of the persistent data is limited, setting an outlet to PERSIST ON should only be used when absolutely necessary, and never for very frequent toggling operations.

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-= Variables: • may be ON or OFF • 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=,2=,3=,4=,5=, 6=,7=,8=,9=,10= 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- Responds with: PHASEANGLE-= 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 where is the 16-byte serial number assigned to the unit.

Channels The PDU uses channels as specified in the following table. Relay On/Off: relay status Temp Scale: Off = C, On = F, The PDU measures temperature with an accuracy of 1 degree C) via a remote temperature probe. Temperature kept in non-volatile storage to retain across reboot. Power Sense: Signals that power (in watts) is above or below the specified trigger level (set via the TRIGGER command). SEND_COMMANDs (Cont.) TRIGGER Syntax: 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. ?TRIGGER Syntax: ?TRIGGER- Responds with: TRIGGER-= to report the trigger value in use on the outlet. VER Syntax: VER Responds with: Version (string) - example: "Vx.xx" ZAP! Syntax: ZAP! Restores all settings on the PDU to factory default settings. Unsupported options in responses are ignored / not reported.

Levels Power (W): Resolution to 0.1W (data scale factor = 10) Current (A): Resolution to 0.1A (data scale factor = 10) Voltage (V): Resolution to 0.1V (data scale factor = 10) Power Factor: W/VA, 2 decimal places (data scale factor = 100). "Power Factor " is the ratio of real power to apparent power. Energy (W-hr): Power over time, resolution to 0.1W-hr (Data scale factor = 10, writing 0 resets counter) Temp (Degrees C or F): Resolution to 0.1C (data scale factor = 10) Resetting Level 4 (Accumulated Energy Reading) The Level 4 value (accumulated energy reading) can be reset to 0 (zero) in three ways: 1. When the PDU is reset or power cycled, Level 4 will go to 0 on all outputs (see Powering On the NXA-PDU-1508-8 on page 9). 2. If SEND_LEVEL ,4,0 is sent, Level 4 will go to 0 on that output (if not already at 0). 3. The max value of the level is 65535, if that is exceeded the level will roll over to 0. Overcurrent Reporting The PDU reports alerts of overcurrent via the following AxLink string: OVERCURRENT-= 16-bit Level Dev 1 Dev 2 Dev 3 Dev 4 Dev 5 Dev 6 Dev 7 Dev 8 1 Power Power Power Power Power Power Power Power 2 Current Current Current Current Current Current Current Current 3 Power Factor Power Factor Power Factor Power Factor Power Factor Power Factor Power Factor Power Factor 4 Energy Energy Energy Energy Energy Energy Energy Energy 5 Input Voltage Ax Voltage 6 Ax 1 Power Ax 2 Power 7 Ax 1 Current Ax 2 Current 8 Temp For power factor, AMX has added an offset of 100 to the value to cope with the possibility of negative numbers. To obtain the correct value of the power factor, first subtract 100 from the level returned by the PDU, then divide by 100. Example: fPowerFactor1 = (LEVEL.VALUE-100)/100.0 //NB fPowerFactor1 is a FLOAT variable” The level range is 0-200. If reporting overcurrent for the entire unit, the outlet # is specified as 0 (zero).
