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):

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.
