4.1.1 SETTING UP QLINK
As mentioned in section 2.9.1, QLINK is a shared bus. If the 3025EMC is connected to an Evertz router
or has multiple control panels, it needs a unique identifier called QLINK ID. This allows the EMC to have
a unique identifier on the shared configuration where multiple panels can connect to multiple channels.
The factory would have set a default QLINK address of 0x0 (in HEX). Otherwise, it would have been set
according to pre-commissioning information that was provided to the factory prior to shipment
To change the QLINK address, use the serial port. On the main EMC-Setup window, choose Options->
Communications. Set the communication to serial port. Choose the PC COM port you will connect a
serial cable to. Set the following comm port settings:
Table 4-2: Serial Comm Port Settings
Connect a straight through D9 serial cable with a rainbow cable (provided with packaging) and connect
to the header on the front of the unit (marked J11 Upgrade).
From main EMC-Setup window, select System -> Comms Window and check that you can get an
Acknowledgment back (.A) from the EMC when you hit the Acknowledge button. Type the following in
the window:
.#90,dx where ‘x’ is the hex address that you want to set.
.#91,d to confirm the hex address (EMC will respond with ‘.A,x’).
Wait for 30 seconds and then reboot the EMC for the changes to be committed. After reboot has been
completed, the new QLINK address should appear on the card edge or can be checked using the
Comms Window and typing:
.#91,d to confirm that the hex address has been configured correctly.
The QLINK address configured must match the hex address for the EMC channel in the EMC-Setup
configuration (see section 4.3.2).
IMPORTANT: The user should keep a record of the IP address and QLINK address they
assign to each EMC channel. The QLINK addresses should be assigned in a numerical
order. (i.e. 0x00, 0x01, 0x02, etc.)
