12.1 Setting Up with HyperTerminal
You can use the Microsoft ® HyperTerminal program on your personal computer to
communicate with your shaker:
1. Before you set up HyperTerminal, be sure to check the Mode and Baud Rate
parameter settings (see Section 7.4.5).
2. While you are in the RS232 screen (see Figure 15), set the Mode parameter to Slave ,
and select the appropriate Baud Rate . The default setting, as you see in your screen,
is 19200; your other choices are 9600 or 38400.
3. Connect the RS-232 cable between your computer and the shaker’s RS-232 port (see
Figure 4).
4. Start HyperTerminal, and follow the steps for Setting a New Connection. When
prompted, select the COM port you will be using, then set the COM parameters (see
Table 17 below):

Flow Control None
5. To be sure that you have established a connection with your shaker, turn the shaker
OFF , open the HyperTerminal connection, then turn the shaker back ON . Once a
connection has been made, the shaker will send an OK to HyperTerminal.
6. You may wish to send a trial command to the shaker (see Sample Test below). We
suggest that you enable Caps Lock on your computer, because all commands must be
sent as capital letters.
Sample Test:
1. To request the current setpoint, type
RS at the terminal. When you type R , you
should see the R on the computer display. This is an echo character, sent back by the
Innova 43/43R. When you type the S , you should see the echo S displayed at the
computer.
2. Use the  Enter key to send the carriage return control character. This will move the
cursor back over the first character.
3. RS is a Request command, so your shaker will send back the data corresponding to
the command.
