INTRODUCTION ORBAN MODEL 5700i
The remote control of overshoot compensation and SCA modulation (see
page 2-43) 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 5700i’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 5700i is processing audio from its analog input.
•
Input: Digital: Indicates that the 5700i 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 2-25.
•
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 2-25.
•
AES Input Error: Indicates that the 5700i’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 2-43 for information on programming the remote control interface.
Computer Interface
On the rear panel of the 5700i 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 5700i package ships with 5700i PC Remote software, an application for any
IBM-compatible PC running Microsoft Windows 2000 (Service Pack 3 or higher), XP,
Vista, or 7. 5700i PC Remote permits you to adjust any 5700i preset by remote con-
trol or to do virtually anything else that you can do from the 5700i’s front panel con-
trols. The program displays all of the 5700i’s LCD meters on the computer screen to
aid remote adjustment.
RS-232 Serial Port
5700i PC Remote can communicate via modem or direct connection between the
computer and the 5700i through their RS-232 serial ports. See
Connecting to the
5700i’s Ethernet Port or Serial Port via a Terminal Program on a PC on page 2-47.
