8 Installating RocketPort/ISA Systems
Installating RocketPort/ISA Systems
from 1 to 16.
c. If applicable, set each port to the appropriate communications mode
(
RS-232 or RS-422 ) for your peripheral using the slide switch.
If connecting a system with a Quad/Octacable:
a. Attach the male end of the Quad/Octacable to the controller.
b. Connect the Quad/Octacable to the peripherals.
If connecting a RocketPort 4J or 8J controller:
a. Connect your peripheral devices to the RJ style connector on the
controller.
After installing and configuring the controller, you are ready to attach your
peripherals. Refer to the Hardware Reference Card if you need information
about the pinouts for the connectors.
After connecting the peripherals, you can go to the next subsection to run the
sample application. The sample application shows you how to use the
API .
Use Section 2 and Appendix A to develop applications.
1.5. Running the Sample Application
The sample program, TERM , is a simple terminal emulator program which
uses one RocketPort port at a time. TERM uses an ASCII terminal connected to
port 0 of the Comtrol interface box with an RS-232 cable. This allows testing
for both transmit and receive. The terminal should be configured for 9,600
baud, 8 data bits, 1 stop bit, and no parity.
Optionally, if you do not have an available terminal to run the sample
application, you can use the loopback plug that came with your controller.
Note: If your configuration is different, you must change the parameters in the
aaOpen call to match your requirements. Make sure you recompile before
running the sample program.
Use the following procedure to run the sample program:
At the
DOS prompt, change to the c: \ROCKET\SAMPLE directory.
12. Type TERM at the DOS prompt. The following displays:
Serial Device Number:
Optionally, insert the loopback plug in Port 0 of the interface box.
13. Type 0 and then press . The following displays:
Serial Device Number 0 Hit F10 to Quit
The TERM application allows you to type any character on the PC keyboard
and have it appear on the terminal, and type any character on the terminal
and have it appear on the
PC screen.
Optionally, if you are using the loopback plug, any character that you type
on the keyboard appears on the screen.
14. Enter several characters using the PC keyboard. You should see these
keystrokes appear on the ASCII terminal.
15. Enter several characters using the ASCII terminal keyboard. You should
see these keystrokes appear on the PC screen.
If the sample fails, see Section 3.
Use Section 2 and Appendix A to develop applications.
