The world of home a utom a tion and integration has been growing at an enormo u s rate
in recent years. Control has been integrated using everything fro m a universal remote
control to a co mplete home automation system to a personal computer.

The R2D7 is an interface that bridges from the RS-232 protocol to a single or multiple
RP-Busses. RS-232 is a common proto co l tha t i s “ sp oken” by every personal computer
and most home automation systems. There are many big names in the hom e
automatio n i n d u stry: Crestron, AMX, Control4, Savant, Vantage, LiteTouch, & Lutron
are considered among the largest. In some cases, an additional component will be
needed by the home automation system in order to use RS-232.

Using an R2D7 allows up 420 hardwired RP60’s or RQ60’s and 5,940 RP60’s or RQ60’s
using a combina tion of hardwired & wireless co ntrols.

2.1. Providing a Power Source

A power source must be provided to the R2D7 on system 1. This source may be either
a DCPM or an “EYE” port of and RP or RQ controller (see figure 2.0.1).

2.2. Providing an RS-232 S ource

The RS-232 source may be any device that i s capable of communicating using the
standard RS-232 protocol. As mentioned before, thi s may include devices such as a
home automati on system or a personal computer.

When configur i ng the R S-232 d evi ce, the following table defines the port settin gs
required by the R2D 7:

Port Speed 9600 baud
Data Bits 8
Parity None
Stop Bits 1
Flow Control XOn / XOff

To make the cable fro m the R S-232 so urce, use the figure 2.2.1. Note that the
“Receive” and “Tr a nsmit” pins on this diagram are the “Receive” and “Transmit” as
labeled on the RS-232 sour ce, not the R2D7.

2.3. Adding Hardwired Systems

When going from system ports other than system 1 on the R2D7, the connection may
go to either an “EYE” or a n “ AU X” port o n the R P 6 0.

2.4. Adding Wireless Systems

The R2D7 has the abil ity to control motors wirelessly using Radio Frequency (RF)
modules when in r adio mode.

Plug the RFTM modul e i nto system 7 on the R2D7 usin g stan d a rd RP-Bus cable (see
figure 2.4.1).

33.. RR22DD77 PPrroottooccooll

Communication wi th the R2D7 is defined in two parts: command stri ng s and response
strings.

3.1. Command Strings

Strings are not cases sensitive to the R2D7, but for our purposes, we wi ll use lower
case for operating strings and upper case for configuration str i n gs.

3.1.1. Operating Strings

Operating stri ngs for the R2D7 are segmented into 5 or 6 parts:

* 1 o 04 020 ;

Each command must beg i n wi th a “ header” character. This character is always the
asterisk: “*”

The next segment is either one or two characters. This represents the system
address, or the physical p ort we are addressing on the R2D7 device. If the R2D7 i s in
radio mode (def a ul t), then thi s number may be anything from 1 through 99. When in
bus mode, however, thi s number may only be 1 though 7. To send the “ALL”
command, use 0 ( zero ) fo r the system.

Next, we need to give the R2D 7 a n instruction as a single character. In our example
above, we have issued the ‘Op en’ command. The following table defi nes the
commands available:

o Open (se nds the o p en co mmand to the sys tem f o r the s pecifie d uni t add ress)
c Close (sends the close command to the system for the specified unit address)
s Stop (sends the s to p co mmand to the sy s tem – unit address is ignored)
w Wind (sends the wind co m mand to the system – unit address is ignored)
p Program a Motor Control (puts the RP60 in programm ing mode)
a Program an Accessory (puts the accessory in programming m ode)
q Quit Sending Current Command (only applicable when sending a “fo rever” com m and)

Now we need to indicate whi ch uni t the command is intended for. This is an address
from our pool of 01 through 60, or 00 to represent “ALL.” The address here is the
same as if the command were issued from a remote contr ol; the R2D7 is simply
another comm a nd sou rce. The address may control a group of shades, single shade,
and even all shades. Perhaps the address for certain controls indicates running to an
intermediate stop .

The next three digits a re an optional timing instruction for the R2D 7 . The value
represents the durati on of the command in 20

th

’s of a second. For example, 010 w ould
be half a second. If this i nfo rm a tion is not specified, then the R2D7 will send the
command for 2 seco nd s. If 0 0 0 i s specif ied, then the command will be sent forever.

Finally, the terminato r must be sent. This can be either the semi-colon (as in our
example) or “CR” ( the “ Enter” key).

7 / 13

3.1.2. Configur ation Strings

Configuratio n strings for the R2D7 are segmented into 3 parts:

* V ;

As with opera ti n g instructions, the first character is the header. This is a l w a ys the
asterisk (“*” ) .

Next is the setting for the R2D7. The following is a table of valid commands:

V Print Version (followed by mode: R = Radio, B = Bus)
R Radio Mode (put system 7 in Radio mode)
B Bus Mode (put system 7 in Bus mode)

Finally, the terminato r is either a semi-colon or the “CR” chara cter .

3.2. Response Strings

Although the RP-Bus is not b i-directional, the R2D7 do es report status information
back to the sender. The f o l l owing table describes the resp onses for each event in the
R2D7:

Event Response
Power On “version, X-on”
Terminator Received “LF” if good command

“U” if command was not understo o d
“CR” after command was relayed to controls

Buffer Overflow “O”
Buffer In Empty “XOn” (Ctrl+Q), b ut o nly if XOf f was sent
Buffer Is Half-Full “XOff” (Ctrl+s)

4.1. Radio Mode

As previously mentioned, the R2D7 is capable of controlli ng up to 42 0 uniqu e motors.
When using RF, this becomes 5940 motors.

See “RR24 User’s Guid e” a nd “RFTM User’s Guide” fo r more information on r a dio
products.

4.1.1. Training the RR433

As with all other radio transmitters, before the RR43 3 will respond to commands from
the R2D7’s RFTM, each R R 4 33 that will be controlled by the R2D7 must be tra i ned .

The first step is to identify the systems that will be controlled by the R 2D 7 . Ea ch
group of RP60’s that is bussed together is co n sidered a system (see figure 4.1.1.1).
Note that in our example, the three systems are arbitrary. They must be numb ered
from 7 or higher, but we could have given each system any number we wanted.

Once the systems have been identified, commands need to be created from the RS­232 source for each system . I n our example, three co mmands would need to be
created, and for simplicity’s sake, we will use the “Stop ” co mm a nd. The three
commands would be: “*12s;” and “*13s;” and “*14s;”

For each system, fol l o w the i nstructions in the “RR433 User’s Guide” to put the
RR433’s on that system into “Lear n” m ode (one system at a time).

Tip:

Especially when dealing w ith systems containing multiple RR4 3 3’s, or w hen the RR43 3
is located a l ong distance from the RS-232 source, it may be easie st to reset the
RR433, causing the “Learn” lig ht to remain on until the first signal is seen.

Send the command fo r that system from the RS-232 source, i.e. send “*12s;” when
the RR433’s on system 12 are in learn mode, etc. The l i g h ts o n the RR433’s in that
system should go out. Repeat these steps for each system of RP60’s.

4.1.2. Controlling Motors

Controlling motors in radio mode is identical to bus mode, except that the system
number may range from 1 to 99.

9 / 13

In our exampl e from the p revious section, we identified systems 12, 13, and 1 4 . So , if
we wanted to close all mo to rs on system 13, we would send the command “*13c00;”

Note:

When sending a com man d to all systems (such as “*0c00; ” ) , the co mmand will
sent to wireless systems. Ea ch system will have to be addressed individual ly.

4.2. Bus Mode

When in bus mode, system 7 on the R2D7 operates identically to the other p or ts.

Before attempti ng to program any devices using the R2D7, read and understand the
section “Programming” in the “RP60’s U ser Guide.”

Devices connected to the R 2D7, whether hardwired or wireless, may be programmed
using RS-232. This is accomplished by emulating the button sequence performed by
hand.

First, the device must b e placed in program mode by sending the “p” comma nd for a
motor control and the “a” command for an accessory (see section 3: “R2D7 Protocol”)
followed by the identi fication number for the device. Next, the sequence must be sent
for the desired f ea ture. Finally, send the “Stop” command to take the device out of
programmi n g mode.

Note:

Before doing any programming from the R2D7, be sure to read the manual for the
device you wish to program.

Example:

Suppose we wish to set a secon d group of 6 to motor (ma i n cha nnel ) 2 on system 4 .
We would need to send the f ollowing sequence of commands to the R2D7:
*4p02;*4c03;*4o06;*4s;

Example:

Suppose we wish to set a “ l ight” threshold to 75 on an SSPB with the default ID on
system 3. We would need to send the following sequence of commands to the R2D 7 :
*3a01;*3c06;*3o07;*3o05;*3s;

Example:

Suppose we wish to enab l e the w i nd lockout for all RP60’s on system 5. We would
need to send the foll owing sequence of commands to the R2D7:
*5p00;*5c10;*5o01;*5s;
