OPTIMOD-FM DIGITAL
mono-from-sum audio input. This also determines the feed to the entire process-
ing chain so that facilities that do not use the 8300's stereo encoder can change
stereo/mono mode and select the source when in mono mode.

Switch the 8300 to use either the analog input or the digital input.

Reduce the stereo main and subchannel modulation to compensate for transmit-
ter overshoot and subcarrier inputs (SCAs).
The remote control of overshoot compensation and SCA modulation (see
page 2-36) 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 8300's internal clock to the nearest hour or to midnight.
You can reconfigure the functions of the eight inputs via System Setup.
For example, if you are not using the stereo encoder, the three inputs
ordinarily dedicated to controlling the state of the stereo encoder can in-
stead be re-configured to call three additional presets.
See page 2-36 for information on programming the remote control interface.

Computer Interface

On the rear panel of the 8300 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 8300 package ships with 8300 PC Remote software, an application for any IBM-
compatible PC running Microsoft Windows 2000 (Service Pack 3) or XP. 8300 PC Re-
mote permits you to adjust any 8300 preset by remote control or to do virtually any-
thing else that you can do from the 8300's front panel controls. The program dis-
plays all of the 8300's LCD meters on the computer screen to aid remote adjustment.

RS-232 Serial Port

8300 PC Remote can communicate at up to 115 kbps via modem or direct connection
between the computer and the 8300 through their RS-232 serial ports.

RJ45 Ethernet Connector

The 8300 can be connected to any Ethernet network that supports the TCP/IP proto-
col.
