The Ground Lift Switch can be set to connect the 8400’s circuit ground to its chassis
ground (in the
GROUND position). In the LIFT position, it breaks that connection. (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 ¼-A-250V for 230V.
The Power Cord is detachable and is terminated in a “U-ground” plug (USA standard),
or CEE7/7 plug (Continental Europe), as appropriate to your 8400’s Model Number.
An RS-232 (PC Remote) Computer Interface, labeled Serial 1, is provided to connect
the 8400 to IBM PC-compatible computers, directly or via modem, for remote control,
metering and software downloads. An additional RS-232 port, label Serial 2, is reserved
for future development.
A Remote Interface Connector is provided to connect the 8400 to your existing trans-
mitter remote control. The 8400 remote control supports user-programmable selection of
up to eight optically isolated 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, over-
shoot compensation, SCA modulation compensation, and clock synchronization. (See
Remote Control Interface Programming on page 2-51.) The 8400 remote control ac-
cepts a dB-25 connector.
The PC-Card Port (PCMCIA) accepts an optional Ethernet card for connecting to net-
work cable, or a Modem card to connect to phone lines, used for remote control and me-
tering,
or software updates. This card is not hot-swappable. Do not insert or remove the
card while the 8400 is powered.
Digital AES/EBU Input and Output are provided to support two-channel AES/EBU-
standard digital audio signals through XLR-type connectors. In addition, an AES/EBU
Sync Input is provided to accept house sync, if required.
Analog Inputs and Outputs are provided to support left and right audio signals through
XLR-type connectors.
