Software Requirements
Operation of 8920MUX modules with version 4.2.0 software or later require
an 8900NET module running version 3.2.0 or later software. To upgrade
your 8900NET module, go to the Grass Valley web site or contact Customer
Service. See
Contacting Grass Valley on page 2 for contact information.
Installation
Installation of the 8920MUX module is a process of:
1. Setting on-board jumpers to determine audio input type (110 Ω
balanced or 75 Ω unbalanced) and remote control lockout,
2. Placing the module in the proper frame slot, and
3. Cabling and terminating signal ports.
The 8920MUX module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indica-
tors reflect the initialization process (see
Power Up on page 12 ).
Setting On-Board Jumpers
Jumpers on the 8920MUX module must be set for remote or local control
and for the audio input type with the following on-board jumpers shown
in
Figure 1 on page 9 :
• Jumper JP10 sets control mode for Local only or Remote and Local.
When a jumper is placed across pins 2 and 3 of jumper block JP10,
module output mode settings are adjustable from the Local on-board
switches only. To have both Local and Remote access, set the jumper
across pins 1 and 2.
• Jumpers JP1, JP5, JP7, and JP8 select either 75 Ω unbalanced or 110 Ω
balanced AES/EBU inputs. All four jumpers must be set for the correct
input type.
