Appendix: Setting Up Serial Communications

This appendix provides instructions for setting up both direct serial and modem con-
nections from your 8500S to your PC. You must do this when you define a new con-
nection from the 8500S PC Remote application. The appendix provides procedures
for both the Windows 2000 and Windows XP operating systems and can be readily
extended by analogy for Windows Vista and 7, although we recommend using
Ethernet connections with Vista or 7. Note that the screen shots were prepared us-
ing Orban's Optimod-FM 8300 but apply equally well to the 8500S.

Preparing for Communication through Null Modem Cable

1. Configure your 8500S.
A) On your 8500S's front panel, navigate to Setup > N
B) Hold down the PC C
on the display.

2. Connect the cable.
A) Connect one end of the null modem cable that we supplied with your 8500S
to the DB9 serial connector on the 8500S'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 8500S per available COM port on your computer. If you wish
to control multiple local 8500S, it is better to use an Ethernet network connection.
However, in principle you could control multiple 8500S serially from one COM port,
using a hardware serial switch to select the 8500S you wish to control. In this case,
you should set up a separate 8500S "connection" for each 8500S to be controlled,
following the instructions below. All connections should reference the same COM
port.
This connection is used both for upgrading your 8500S and for connecting the 8500S
PC Remote application to your 8500S.
Important: The Direct Serial Connection must have exclusive access to the PC COM
port that connects to your 8500S. 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
