Appendix: Setting Up Serial Communications

This appendix provides instructions for setting up both direct serial and modem
connections from your 5500 to your PC. You must do this when you define a new
connection from the 5500 PC Remote application. The appendix provides procedures
for both the Windows 2000 and Windows XP operating systems. Note that the
screen shots were prepared using Orban's Optimod-FM 8300 but apply equally well
to the 5500.

Preparing for Communication through Null Modem Cable

1. Configure your 5500.
A) On your 5500's front panel, navigate to Setup > N
B) Hold down the PC C

2. Connect the cable.
A) Connect one end of the null modem cable that we supplied with your 5500 to
the DB9 serial connector on the 5500'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 5500 per available COM port on your computer. If you wish
to control multiple local 5500s, it is better to use an Ethernet network connection.
However, in principle you could control multiple 5500s serially from one COM port,
using a hardware serial switch to select the 5500 you wish to control. In this case,
you should set up a separate 5500 "connection" for each 5500 to be controlled, fol-
lowing the instructions below. All connections should reference the same COM port.
This connection is used both for upgrading your 5500 and for connecting the 5500
PC Remote application to your 5500.
Important: The Direct Serial Connection must have exclusive access to the PC COM
port that connects to your 5500. Make sure than 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 2-58.
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
