RS-232C is a standard serial interface. An explanation of the connections used by the R-1000 is given below.
Connector and cable
fig.PinRS232C.eps
To set up the R-1000 and the computer that will control it, proceed as follows:
1. Connect the control computer.
Use a RS-232C cable to connect your computer and the R-1000.
“Connection with the control computer” (p. 3).
2. Power up the computer that will be controlling the R-1000.
3. Make settings for the control computer
Perform the communication settings.
“Settings on the control computer” (p. 3).
4. Make settings on the R-1000.
Perform the communication settings.
“Settings on the R-1000” (p. 3).
5. Start operating the R-1000.

Setup
1. Power off the R-1000 and the computer.
2. Use an RS-232C cable to connect the RS-232C connector of your computer to the RS-232C connector located on the back of
the R-1000.
For details on the cable to use, refer to “Connector and cable” (p. 2).
Communication settings on the computer
• Communication method Synchronous (asynchronous), full-duplex
• Communication speed 4800 / 9600 / 14400 / 31250 / 38400 / 57600 / 115200 bps
(You can select this as desired, but it must be the same as the setting on the R-1000.)
• Parity none
• Data length 8 bit
• Stop bit 1 bit
• Code set ASCII
• Flow Control none
* For details on how to set the communication settings, refer to the owner’s manual of the computer you’re using.
When you power up the R-1000, the communication speed will be set to 115200 bps by default. If you’re using the R-1000 via RS-
232C, you’ll need to set its communication speed to match the setting of the computer.
For details on how to set this, download “R-1000 Application Guide“ from the Roland website below and refer to it.

Overview of commands
The R-1000 and the control computer communicate via commands. There are several types of commands, and you can control
the R-1000 by using the command that’s appropriate for your purpose.
Single-byte alphanumeric characters are used for commands. In general, the command syntax is an ASCII string consisting of “stx”
and “three uppercase letters” followed by a “;” (semicolon). The three letters indicate the type of command. However, there are
other types depending on the command.
“Command syntax” (p. 5).
* “stx” : This is the control code in ASCII code (code number 02H in hexadecimal); it indicates the beginning of a command.
* “;” : This code lets the R-1000 detect the end of the command.
<Ex.> To transmit the ** command, transmit the ASCII string “stx**;”
Depending on the command, there are two types of communication protocols between the control computer and the R-1000.
When specifying an operation or setting for the R-1000
This type corresponds to the “Control commands” (p. 6). These commands use the procedure shown in the following diagram.
fig.PrtConcept1.eps
a. Transmit the command from the computer to the R-1000.
b. The R-1000 will output “ack” if the command was received correctly, or an ERR command in case of invalid reception.
* “ack” : This is the ASCII code name of the control code (06H in hexadecimal) acknowledging successful reception.
* Invalid reception corresponds to cases in which the syntax of the received command was incorrect.
* stxERR is the command used to transmit or receive an error indication.
To learn the settings of the R-1000
This type corresponds to the “Request commands” (p. 7). Commands used to check the status of a setting in the R-1000 use the
following procedure.
fig.PrtConcept2.eps
a. Transmit the command from the computer to the R-1000.
b. If the R-1000 receives the command correctly, it will send back a command containing the information that was requested. If
the command was not received correctly, an ERR command will be sent back.
c. If the output of the R-1000 was received correctly, an “ack” will be sent back. (* This “ack” can be omitted.)
* If the ERR command is sent to the R-1000, the R-1000 will re-transmit the command it sent in step “b.” This command can also be omitted;
instead of returning anything, you can repeat the procedure from step “a.”
* The R-1000 will not transmit anything when a setting is changed by a controller operation on the R-1000 itself.

Overview of commands
There are several possible types of syntax for commands (control signals).
Type 0: Commands consisting only of a control code
“;” is not added to these. They consist only of the control code.
<Ex.> ack
Type 1: Commands that have no parameters
These commands end with “;”.
<Ex.> stxVRQ;
Type 2: Commands that have parameters
Command: parameter, parameter...;
• The command is separated from the parameters by a “:” (colon).
• Parameters are separated by a “,” (comma).
• The end of the parameters is indicated by a “;” (semicolon).
* No spaces or tabs are allowed between commands or parameters.
In general, parameters are given as decimal numbers or letters, and are of variable length.
stxPYC;/stxSTC;/stxLCC:01h48m24s10f;
Parameters are generally given in decimal or alphabetic form, and their length may vary.
stxSTS:0;/stxLCS:01h48m24s10f;
Do not perform the following actions while the control computer and the R-1000 are communicating. Doing so may cause the R-
1000 to malfunction.
• Disconnect the RS-232C cable
• Power off the R-1000

Command details
The following three types of commands are sent from an external device to the R-1000.
Control (execution) commands
These commands are used to adjust the volume and to make various settings.
Request commands
These commands are used to check the current state of the R-1000’s settings.
After performing a control operation, you should use a request command to check the state of the settings.
Reply commands
Commands such as “ack” and “ERR” are in this category. These commands are used to reply to the R-1000 when a request
command is used.
