7.9 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 +8.4 V. They each source
400 uA when grounded. An automation input control pin needs to be pulled below 2.6 V for
50 ms or more for the JSD-60 to recognize it as low. A +5 V source with up to 100 mA 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. A series 10-ohm resistor limits 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 38.4 kbps, 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 10/100 Mbps 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 five 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.
