System Addresses
Each Quad Input Manager Module contains four microprocessor/scaler engines that
each control one LCD. Each microprocessor has an address to which the master uses
to communicate with. These are also the addresses that an external host computer
will use when controlling the system through RS232. Unlike other Runco wall
products, these addresses are determined by the system, not by the installer. Each
Quad Input Manager Module has a letter address: A through P. This address is set via
the address selector switch on the front of the module. You must set this selector so
that each Quad Input Manager Module in your system has a unique address. Each
Quad Input Manager Module has four processors, numbered 1 through 4. The
address of each processor is the combination of the Quad Input Manager Module
letter address and the processor number address. For example, A1, A2, A3, A4, B1, B2,
B3, B4, etc. Throughout this manual we will be using these addresses to refer to these
processors.
Since each processor controls one LCD, we will also be referring to LCDs by this
letter/number designation. Keep in mind that if you change where the video and
data cables were connected for a particular LCD, its address will change.
An LCD’s
address is not determined by its position in the array, rather by its Quad Input Manager
Module connection
.
Each Quad Input Manager Module also has four DVI input connections. These four
inputs are closely associated with the corresponding LCDs. So in this manual we will
also be referring to these connections by letter and number designations, A1, A2, A3,
etc. Whether an address refers to an input, a processor, or an LCD will be apparent
from the context.
Quad Input Manager Module A, and specifically processor A1 has special duties. It is
referred to in this manual as the master. The IR remote input, the (optional) host
RS232 connection and the (optional) WallNet RS232 connections are all made on
processor A. LCD A1 displays most of the menus.
