System Configuration - Lutron Radio Touch RTA-RS232 Guide D'installation Et De Mise En Service

Protocol (continued)
Zones
A zone is an accessory or group of accessories,
such as lights or Sivoia QED controllable shades,
controlled simultaneously as a single unit. The
RS232 interface can control up to 10 zones,
numbered 0 through 9. Each zone can be
configured as lights or contact closures. As shades
are controlled by a RF controller's contact closure
outputs, shade zones are configured as contact
closures zones.
Functions
The following functions are available through the
RTA-RS232.
Setting Lighting Zone Levels
Lighting zone level refers to the intensity of the
light. The zone may be set to an explicit level, a
preset level, or raised/lowered. The explicit levels
include a continuous range, or a specific level. See
page 15 for a complete description of each explicit
level.
For a continuous range, a value of 0 indicates off;
a value between 1 and 100 represents intensity, in
percent, between low end and high end.
There are a total of 16 presets available. Preset
light intensities are stored in the RF controller.
When an RF controller receives a Preset
command, it adjusts its light intensity to the value
stored in the Preset.
When the RTA-RS232 receives a command to
raise or lower the zone intensity, it commands the
intended zone to raise (lower) its intensity for 5
seconds, or until it receives the ESTP (End Step)
command.
Controlling Contact Closures
Contact closure zones respond only to preset
levels. Any other type of level will result in an error.
When a contact closure zone receives a preset
command, it will activate the switch closure
associated with that preset for 250 milliseconds. If
the preset number is greater than 5, it will ignore
the data and send an error message if the unit is in
Reply Back Mode.

Setting Presets
The preset light level for a lighting zone may be set
via the RTA-RS232. In order to do this, however,
DIP Switch 1 on the RF controller in the intended
zone must be in the down position or the zone
must have received the enter Preset Adjust Mode
from the RS232 interface or one of the transmitters
in the room. Once this is done, any or all the
presets for that zone may be set. Once the presets
are set, the DIP Switch on the RF Controller must
be placed in the up position or the exit Preset
Adjust Mode command must be sent.

System Configuration

When setting the RTA-RS232 configurations, the
host must first enter Configuration Mode. After
completing the configurations, the host must then
exit Configuration Mode. If the system is in
Configuration Mode, the only commands that the
RTA-RS232 will execute are Configuration
commands. All other commands will be ignored.
Conversely, if the RTA-RS232 is not in
Configuration Mode, it will ignore Configuration
Commands.
Zones
Zones may be configured as one and only one of
the following: Lights, Contact Closures, or
Unassigned. There are a total of 10 zones available
on the RS232 interface, numbered 0-9. These
zones may be configured either by software
control over the data link, or manually using the
programming buttons on the RTA-RS232 unit. The
default zone configuration is Unassigned.
Reply Back
The RTA-RS232 has the ability to reply to the host
whether it processed the last command
successfully or not. This mode can be turned on or
off. If Reply Back is turned on, and the RTA-RS232
successfully processes a command, the RTA-
RS232 will respond to the host with:
~OK<CR>
