2.9.1. QLINK
In Figure 2-5, Q-Link is a dedicated control system specific to Evertz brand of Quartz products. The Q-
Link system works as a single transmission line with devices connected along the length of the cable. It
must be terminated at either end by 75Ω. The 3025EMC frame has pairs of looping connectors to allow
the frame to sit at one end of the link (with termination) or sit in the middle of the link with cables running
off in different directions.
In the case of the EMC, QLINK is used to interconnect Evertz routers (EQT, Xenon, and EQX) with the
EMC. This is the interface used by the EMC to control the Evertz upstream router. This a looped
input/out to allow for daisy chaining of multiple EMCs (up to 4) on a single QLINK connection to the
router.
2.9.2. EXT DVE IN & EXT DVE OUT
These inputs and outputs are for future use. They currently have no functionality and should not be
wired.
