Appendix: Setting Up Serial Communications
This appendix provides instructions for setting up both direct serial and modem
connections from your 8685 to your PC. You must do this when you define a new
connection from the 8685 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 8685 as well.)
Preparing for Communication through Null Modem Cable
1. Configure your 8685.
A) On your 8685’s front panel, navigate to System S
ETUP / NETWORK & REMOTE.
B) Set the S
ERIAL INTERFACE TYPE to DIRECT.
2. Connect the cable.
A) Connect one end of a null modem cable to the DB9 serial connector on the
8685’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 8685 per available COM port on your computer. If you wish
to control multiple local 8685s, it is better to use an Ethernet network connection.
However, in principle you could control multiple 8685s serially from one COM port,
using a hardware serial switch to select the 8685 you wish to control. In this case,
you should set up a separate 8685 “connection” for each 8685 to be controlled, fol-
lowing the instructions below. All connections should reference the same COM port.
This connection is used both for upgrading your 8685 and for connecting the 8685
PC Remote application to your 8685.
Important: The Direct Serial Connection must have exclusive access to the PC COM
port that connects to your 8685. Make sure than any software that monitors this
COM port (like HotSync manager, etc) is disabled before running Direct Serial Con-
nection.
If you have already configured your direct serial cable connection, skip to step 2 on
page 2-72.
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
