Instruction Manual - Enova DVX-325xHD/22xxHD All-in-One Presentation Switchers
The following table lists the pinouts for the RS-232/422/485 ports.
In the above table, pin 1 is located on the right side of the port, and the pinouts count up to the left.
Relay Ports
The relay ports (port 21 on the DVX) are 8-pin 3.5 mm mini-Phoenix (male) connectors used for connecting external relay devices.
The DVX-325xHD features 2 sets of 8-pin relay connectors. The DVX-22xxHD features one set of connectors. You can connect up to
8 independent external relay devices on the DVX-325xHD, and 4 on the DVX-22xxHD. When a relay is "OFF", terminals A and B are
open-circuit. When a relay is "ON", terminals A and B are shorted together.
Relay Connections
Use connectors A for common and B for output (FIG. 48). Each relay is isolated and normally open.
A metal connector strip is also provided to common multiple relays.
