Using the RS-232C interface
RS-232C is one of the industry standards for serial interfaces.
The cable wiring of the RG-100 is as shown below.

This is how to set up the control PC and the RG-100.
1.
Connect the RG-100 to the control PC.
Connect both devices together using the RS-232C interface
cable. Refer to the following “Connecting the RG-100 with the
control PC.”
2.
Turn on the control PC.
3.
Set up the control PC.
Set the communication settings. Refer to the following “Setting
up the PC.”
4.
Set up the RG-100.
Set the communication settings. Refer to the following “Setting
up the RG-100.”
5.
Start operating the RG-100.
Operate the RG-100 with the control PC.
1.
Turn off the power of the RG-100 and the control PC.
2.
Connect the RS-232C interface cable from the control PC to
the RS-232C connector on the rear panel of the RG-100.
Use a cable as specified in “The connector and cable.”
The communication settings of the
control PC
• Communication protocol: Start-stop system (asynchronous) full
duplex.
• Baud rate: 1,200/2,400/4,800/9,600/19,200/38,400 bps. You can
select from any of these, and set the same baud rate on the RG-
100.
• Parity: None
• Data length: 8 bytes
• Stop bit length: 1 bit
• Code: ASCII
• Flow control: Hardware flow control
For instructions regarding the communication settings, refer to
the instruction manual of the control PC.
About flow control
When you send some data from your PC and if the data processing
speed of the RG-100 is slower than the baud rate, you need to
perform some kind of process, otherwise a part of the data will be
lost. In the same way, when data is sent from the RG-100 and the PC
data processing speed is slower than the baud rate, some data will be
lost too. This is why hardware flow control is applied to the RG-100.
The external PC can also control the data transmission from the RG-
100.
When using the RS-232C interface connection with the RG-100, you
need to set up the baud rate.
Also, to control the RG-100 with the RS-232C interface, the unit
needs to be in Play Mode.
About the baud rate
At the factory defaults, the baud rate of the RG-100 is set to 9,600
bps.
To change the baud rate, set up the unit as follows.
