Enova DVX-3150HD/3155HD All-in-One Presentation Switcher Operation/Reference Guide
AxLink Port and LED (4-pin captive-wire)
The AxLink port (FIG. 46) allows the DVX to support AMX AxLink devices.
The (green) AxLink LED indicates AxLink data activity:
Off
- No power, or the controller is not functioning properly.
1 blink per second
- Normal operation.
3 blinks per second
- AxLink bus error. Check all AxLink bus connections.
The AxLink port can be used to supply power to downstream AxLink-compatible devices as long as the
maximum current draw is
less than
1 Amp. To isolate the DVX from high inrush current, AxLink devices, or
potential power faults on the AxLink bus, it is strongly recommended that you power external AxLink devices
from an independent power supply.
Refer to the following table for the wiring length information used with the DVX:
FIG. 47 provides wiring requirements for the AxLink connector:
FIG. 46
AxLink Port and LED
The AxLink port provides only limited power to connected AxLink devices. It is
recommended to use an alternate power source when connecting AxLink devices to
the DVX.
When using the DVX with the NXA-PDU-1508-8 power distribution unit, do NOT
c12V power from any of the NXA-PDU's AxLink ports to the AxLink power
pin.
