REMOTE CONTROL
One or more SuperQuads may be controlled via RS-232 lines from an
AD1475RT keyboard, terminal, or computer using standard,
uppercase ASCII codes. The ASCII command codes for the
SuperQuad functions are listed in the table below.

If set for Manual Mode
Each command code sent to the SuperQuad is a 2-character pair, with
no spaces between the characters. For example, the command to
switch to camera 3 is "K3" and the command to enter Expand mode is
"KX".
UNIT IDENTIFICATION (ID#)
For remote control, each SuperQuad is programmed with a Unit
Identification number from 0 to 9 (0 to 8 when used with the
AD1475RT Remote Control Unit). As delivered, the SuperQuad Unit
ID is set to 0, which is the global response mode. The global response
mode allows the SuperQuad to respond to command codes sent to any
Unit ID on the RS-232 line. The Unit ID of the SuperQuad can be
changed by Setup Mode Security Options menu, page 9.
The Unit ID number transmitted in the connect code (L ID#) directs
the specified SuperQuad to respond to all subsequent command codes
until a disconnect code is received. When the Unit ID transmitted in
the connect code is 0 (i.e., LO), all SuperQuads on the RS-232 line
respond to subsequent command codes
until a
disconnect is received.
KEYBOARD CONTROL
The AD1475RT keyboard can control one or more SuperQuads via the
RS-232 interface. Dedicated buttons are provided on the keyboard for
all SuperQuad functions except the Setup Mode menus. These menus
can be accessed only from the SuperQuad front panel. Refer to the
AD1475RT Installation Manual for specific information on the use of
this keyboard to identify and control the SuperQuad.
COMPUTER LOGIN and CONTROL
When connected to a terminal or computer, the controlling system
must first connect/login to the SuperQuad. There are two methods
provided: individual unit or broadcast login.
Prior to login, set the SuperQuad Unit ID using the Security Options
menu in Setup Mode, page 9. (As shipped, the Unit ID is set to 0.) For
individual SuperQuad control, each unit on the RS-232 line should be
set to a unique Unit ID.
For individual unit login:
This method directs command codes to a specified SuperQuad, and to
any SuperQuad set to a Unit ID of 0 (global response).
1. To login for individual unit control, first send an ASCII "L"
immediately followed by an ASCII Unit ID number.
For example, assume the Unit B) is set to 4; to connect to this unit,
send the login code "L4".
2. At this point, the user or program can send any pair of "K"
command codes desired.
3. To stop sending commands to the specific unit, log out by
sending the code "LA".
For broadcast login:
This method allows the user to control a single SuperQuad without
knowing its Unit ID, or to control all SuperQuads on the RS-232 line.
1. To login for broadcast control of one or more SuperQuads,
first send an ASCII "LO".
2. At this point, the user or program can send any pair of "K"
command codes desired.
For example, to send a broadcast message for all SuperQuads to
switch to Camera 1, the ASCII character sequence would be
"LOKI".
3. To stop sending commands in the broadcast mode, log out
by sending the code "LA".
