Room Audio (RA2) Card Jumper Settings
The ML-116 RA2 cards contain two jumper fields to allow page mode configuration The jumpers
determine whether or not "Normal Paging" occurs during Mic or Music functions. A four position
jumper field is provided for each room. Each bank of jumpers is clearly labeled as either “Low Room”
or “High Room”. Within a bank of jumpers, one pair is labeled “Page Thru Music” and the other pair
“Page Thru Mic”. Within a pair of jumpers, one jumper is labeled “Y” for yes, and the other “N” for no.
The system is factory configured to allow Normal Mode Paging during music but not while mics are
enabled (Page Thru Mic = Y; Page Thru Music = N). You may reconfigure the system to operate as
required on a room by room basis. For example, to allow Normal Mode Paging to occur during Mic and
Music, set both the Page Thru Mic and the Page Thru Music jumpers to Y. In most cases, all rooms
within a system should be configured with the same jumper settings to ensure consistent page opera-
tion.
In certain cases, it may be desirable to set the page jumpers differently for different rooms. An example
of this would be when a single ML-116 system is used to control two different ballrooms or a single
ballroom with a surrounding corridor.
WALLPLATES
The wallplates used in the ML-116 system are membrane. They control all wallplate functions. These
functions include Music Selection, Local Mixer, Music Enable and Volume, and Microphone Enable
and Volume.
When the wallplates sense a key press it waits for a poll from the ACU then it sends a message to the
ACU which will return an update message. The wallplates will then check for another keypress and
repeat. Internal flags will prevent the wallplates from acting on the same keypress until the update
message is returned. This whole process occurs within a fraction of a second.
The wallplates communicate with the ACU over a RS-422 line and are addressable. This address is a
5 bit address (0-31) allowing the use of up to two (2) wallplates per room.
