INTRODUCTION

Computer Interface

RS-232 Serial Port

The remote control of overshoot compensation and SCA modulation (see
page 2-42) is not latching. You must supply a continuous current to the
programmed remote input to hold the gain at its compensated level. Use
the status outputs of your transmitter and/or SCA generators to provide
the switching signal so the compensation will automatically follow the
transmitter and/or subcarrier generator on the air.

Reset the 8500S's internal clock to the nearest hour or to midnight.
The tally outputs can be programmed to indicate the following:
•
Input: Analog: Indicates that the 8500S is processing audio from its analog input.
•
Input: Digital: Indicates that the 8500S is processing audio from its AES3 digital
input.
•
Analog Input Silent: Indicates that the level at either or both analog input chan-
nels is below the threshold set in step (A) on page 2-24.
•
AES Input Silent: Indicates that the level at either or both digital input channels
is below the threshold set in step in step (A) on page 2-24.
•
AES Input Error: Indicates that the 8500S's AES input receiver chip has detected a
problem with the data being received such that the data is unusable. When the
chip detects such an error, it automatically switches the input to Analog.
•
No Function: Tally output is disabled.
You can reconfigure the functions of the inputs and outputs via System Setup. For
example, if you are not using the stereo encoder, the three inputs ordinarily dedi-
cated to controlling the state of the stereo encoder can instead be re-configured to
call three additional presets.
See page 2-42 for information on programming the remote control interface.
On the rear panel of the 8500S are an RS-232 serial port and an Ethernet port for in-
terfacing to IBM-compatible PCs. These computer interfaces support remote control
and metering, and allow downloading software upgrades.
Each 8500S package ships with 8500S PC Remote software, an application for any
IBM-compatible PC running Microsoft Windows 2000 (Service Pack 3 or higher), XP,
Vista, or 7. 8500S PC Remote permits you to adjust any 8500S preset by remote con-
trol or to do virtually anything else that you can do from the 8500S's front panel
controls. The program displays all of the 8500S's LCD meters on the computer screen
to aid remote adjustment.
8500S PC Remote can communicate via modem or direct connection between the
computer and the 8500S through their RS-232 serial ports. See Connecting to the
8500S's Ethernet Port or Serial Port via a Terminal Program on a PC on page 2-47.
