a per-format basis. The VI-N audio output is typically driven by AES/EBU input 8. The HI audio output can be
driven from AES/EBU input 7 or from an audio mix via the channel mixer located in the “Advanced” tab in the
Windows GUI.

Automation Interface
The JSD-60 includes the traditional parallel automation interface plus RS-232 and Ethernet. This interface will
accept the JSD-100 automation commands to simplify the installation and setup.
Parallel Interface
Pins 1 through 10 of the DB25F automation connector are “control” pins that accept contact closure or open
collector pulses to ground to select formats and to control the main fader. To change the selected format, the
corresponding pin, 1 through 7 is pulsed. Pulsing pin 8 low toggles the mute state. Pins 1 through 10 are internally
pulled up to +8.4V. They each source 400uA when grounded. An automation input control pin needs to be pulled
below 2.6V for 50ms or more for the JSD-60 to recognize it as low. A +5V at 100mA is available on pin 13 to drive
an external remote fader control (JSDV-80). Pin 12 is the “automation return.” Use this as the low side of switches
and indicators instead of using chassis ground. It is ground through a 10 ohm resistor to limit ground loop current.
RS-232 Interface
The RS-232 interface appears on a DE9F connector on the rear panel. The connector is wired as a DCE device. A
command interpreter accepts ASCII commands (described in Appendix B) over the RS-232 and Ethernet interfaces.
The RS-232 port operates at 38.4kbps, 8N1 (8 data bits, no parity, 1 stop bit), no handshake. RTS/CTS and DTR/DSR
are looped back.
Ethernet Interface
The JSD-60 includes a standard 10/100Mbps Ethernet interface. The same automation commands (described in
Appendix B) are available on TCP connections to port 10001 on the Ethernet interface. The JSD-60 accepts up to 5
simultaneous TCP connections, allowing multiple control and monitor devices to be used. The Ethernet interface
also includes a web server. System status and basic control are available on internally generated web pages.
System status is also available over SNMP. The JSD-60 also includes a Network Time Protocol (NTP) client that can
be used to keep the internal real time clock accurate. Use a CAT5 or better Ethernet cable to connect the JSD-60 to
the control network.
8. Graphical User Interface Configuration
System Configuration using the Graphical User Interface
The graphical user interface (GUI) allows for configuration and
monitoring of the JSD-60. When installed, the JSD-60 GUI programs
item and a desktop shortcut are created. The application is located
in the c:\Programs (x86)\USL\JSD-60 Cinema Processor folder. The
JSD-60 SetIP utility, User Manual, and DPInst64 USB driver are
located in this folder.
8.1
GUI File Organization
The GUI installer places the executable program files in the Programs
(x86) \USL\JSD-60 directory. Configuration files are placed in
Documents\USL\JSD-60 as shown.

The EQ Curves directory holds data for generating limit curves
for the RTA and automatic equalization. Standard curve data
for several auditorium sizes are provided. Since these are plain
text files, custom limit curves can be easily created.
