NOTE: Ethernet control access to the EQT is achieved via user-defined ports as
explained in Section 8.1
Section 8.1.1 describes the method used to set up the EQT for use with Ethernet control panels. Consult
the instruction manual for the respective panels for information regarding their IP address setup.
4.4.2. Controlling the EQT using Serial
The rear panel of the EQT has a D-Sub female serial connector labeled DEBUG/SERIAL. The EQT
supports Quartz protocol commands over the serial port (slave end). Any control device that supports
Quartz protocol can control the EQT via the serial port.
For information regarding the Quartz protocol, contact Evertz service. See section 2.3.2 for a description
of the pin-outs of the serial port.
4.4.3. Controlling the EQT using GPIO
There are two 8-pin Phoenix connectors on the EQT’s rear, labeled GPI and GPO.
The GPIs are Opto-isolated inputs that can be powered from an external source or from the frame. The
GPOs are relay contacts that are normally closed when the power to the router is off. However, once the
power is on, its state can be changed to normally open – see details in the Web page (Section 6.8) or
VistaLINK® (Section 7.8).
The GPI’s are used to activate video bus crosspoints and can be configured to operate in two modes,
Low and High level:

Low level activation is when a ground level on the input triggers the GPI function when the opto-
isolator is normally powered.

High level activation is used to trigger the GPI function by providing a positive voltage to a GPI
input. The mode is not generally used and should not be considered a first choice.
Also, the GPIs can be individually encoded to work independently or collectively to trigger up to four
routes, with distinct sources/destinations:

Individual Function: The four GPIs can trigger up to four specific routes each. Once the routes
per GPI are set in the Web page (Section 6.8.1) or VistaLINK® (Section 7.8.1), each GPI can be
triggered by any of the options depicted in Figure 4-4, Figure 4-5 and Figure 4-6.

Encoded Function: The four GPIs can be encoded as a single integer value, allowing the
associated source to be routed to a specific destination(s) set in the Web page or VistaLINK®.
The bits of the integer value are identified as a source. A GPI value of 0000 Binary (GPI1 as the
LSB) equated to source 1 and a value of 1111 Binary equated to source 16 – see Table 4-1 for
source selecting.
