The Ground Lift Switch can be set to connect the 8300's circuit ground to its chas-
sis ground (in the G
(See Set Ground Lift switch on page 2-3.)
The Voltage Select switch can be set to 115V (for 90-130V operation) or 230V (for
180-260V operation).
Fuse values can be changed to support 115V or 230V operation. For safety, use ½-A
250V Slow-Blow for 115V, or 250mA-250V for 230V.
The Power Cord is detachable and is terminated in a "U-ground" plug (USA stan-
dard), or CEE7 / 7 plug (Continental Europe), as appropriate to your 8300's Model
Number.
An RS-232 (PC Remote) Computer Interface, labeled S
connect the 8300 to IBM PC-compatible computers, directly or via modem, for re-
mote control, metering and software downloads.
A Remote Interface Connector allows you to connect the 8300 to your existing
transmitter remote control or other simple contact-closure control devices. The 8300
remote control supports user-programmable selection of up to eight optically iso-
lated inputs for any one of the following parameters: recalling any factory- or user
presets, tone or bypass modes, selecting stereo encoder modes (stereo, mono-left,
mono-right, mono-sum), selecting analog, digital or digital+J.17 input, overshoot
compensation, SCA modulation compensation, and clock synchronization. (See Re-
mote Control Interface Programming on page 2-36.) The 8300 remote control ac-
cepts a DB-25 connector.
The Ethernet Port accepts a 10Mb/second or 100Mb/second Ethernet connection
terminated with an RJ45 connector.
Digital AES3 Input and Output are provided to support two-channel AES3-
standard digital audio signals through XLR-type connectors.
Analog Inputs and Outputs are provided to support left and right audio signals
through XLR-type connectors.
Two Composite Baseband Outputs are provided, each with independent output
level control. Each output uses a BNC connector.
Two SCA Inputs are provided for stations that use additional subcarriers (SCAs).
Each input uses a BNC connector. The second SCA input can be reconfigured via an
internal hardware jumper as a Pilot Reference Output useful for RDS (RBDS) subcar-
rier generators that require an external sync reference.
