Instruction Manual - Enova DVX-325xHD/22xxHD All-in-One Presentation Switchers
I/O Ports
The I/O ports (port 22 on the DVX) are 6-pin 3.5 mm mini-Phoenix (male) connectors used for connecting logic-level outputs. The
DVX-325xHD features 2 sets of 6-pin I/O connectors; the DVX-22xxHD features 1 6-pin connector. The
I/O port responds to either switch closures, voltage level (high/low) changes, or it can be used for logic-level outputs. Each port is
capable of being used as an input or an output.
FIG. 49 displays the I/O ports for each DVX model.

I/O ports
A contact closure between the GND and an I/O port is detected as a Push.
When used for voltage inputs, the I/O port detects a low signal (0 - 1.5 VDC) as a Push, and a high signal
(3.5 - 5 VDC) as a Release. (This I/O port uses 5V logic but can handle up to 12V without harm).
When used for outputs, the I/O port acts as a switch to GND and is rated for 200mA @ 12 VDC.
The DVX-22xxHD can use up to 4 I/O ports
The DVX-325xHD can use up to 8 I/O ports
The PWR pin pr12 VDC @ 200 mA and is designed as a power output for the PCS Power Current Sensors, VSS2
Video Sync Sensors (or equivalent).
The GND connector is a common ground and is shared by all I/O ports. A common ground is shared with
I/O ports 1-8 (DVX-325xHD) or with I/O ports 1-4 (DVX-22xxHD).
The input impedance on the I/O port is 22k.
In the above table, pin 1 is located on the right side of the port, and the pinouts count up to the left.
