Appendix: Setting Up Serial Communications
This appendix provides instructions for setting up both direct serial and modem
connections from your 9400 to your PC. You must do this when you define a new
connection from the 9400 PC Remote application. The appendix provides procedures
for both the Windows 2000 and Windows XP operating systems. (Note that the
screen shots were prepared for Orban’s Optimod-FM 8300 and refer to that product.
They are directly applicable to the 9400 too.)
Preparing for Communication through Null Modem Cable
1. Configure your 9400.
A) On your 9400’s front panel, navigate to S
ETUP > NETWORK & REMOTE.
B) Hold down the PC
CONNECT soft button and turn the knob until you see
D
IRECT on the display.
2. Connect the cable.
A) Connect one end of the null modem cable that we supplied with your 9400 to
the DB9 serial connector on the 9400’s rear panel.
Be sure to use a null modem cable. A normal serial cable will not work.
B) Connect the other end of the cable to your computer’s COM port.
Connecting Using Windows 2000 Direct Serial Connection:
Ordinarily, a direct serial connection through a null modem cable is used only when
you are controlling one 9400 per available COM port on your computer. If you wish
to control multiple local 9400s, it is better to use an Ethernet network connection.
However, in principle you could control multiple 9400s serially from one COM port,
using a hardware serial switch to select the 9400 you wish to control. In this case,
you should set up a separate 9400 “connection” for each 9400 to be controlled, fol-
lowing the instructions below. All connections should reference the same COM port.
This connection is used both for upgrading your 9400 and for connecting the 9400
PC Remote application to your 9400.
Important: The Direct Serial Connection must have exclusive access to the PC COM
port that connects to your 9400. Make sure that any software that monitors this
COM port (such as HotSync manager, etc) is disabled before running Direct Serial
Connection.
If you have already configured your direct serial cable connection, skip to step 2 on
page 2-64.
If
you cannot access the Internet after making a Direct or Modem connection, you
will have to reconfigure certain networking parameters in Windows. Please see You
