Connections for Synchronized Multi-player Operation
The following equipment is required for an example of a small synchronized system:
Two JMP 9600 Media Players (see figure 67, below)
One or more LTC cables terminated with male RCA connectors (in red on figure 67)
One or more Lock (ESGEN or MSGEN genlock) cables terminated with 6-pin mini-DIN
connectors (shown in blue on figure 67)
A computer that is running show control software
Ethernet or serial (RS-232) remote control cabling
A synchronized system requires that one device in the system is configured as the master
device which generates the timing references for the entire system. All other devices in the
system are configured as slaves.
The JMP 9600 can either generate a master timing references or operate as a slave. For
the purposes of this discussion, assume that one of the media players is configured as the
master. The media player can also present some clips in master mode and others in slave
mode.
The slave player must be set to Chase mode (see “Video submenu“ to set the mode from
the front panel) to continuously lock to the master player. In trigger mode, the slave player
starts playback at the predefined Playat time and free runs after that.
NOTE: The two media players in this example are designated as the “master player”
and “slave player” for the remainder of this discussion.
The master player distributes LTC and proprietary genlock (if configured) to all other devices
in the system that need it (slaves). Typically, a slave generates its output based on the timing
references it receives. For example a lighting system can be programmed based on the LTC it
receives to generate a lighting scene or effect when a certain timecode is received.
The master player outputs LTC on its LTC Out connector (see figure 67). The slave player
receives LTC on its LTC In connector and syncs itself to the master player. If the master player
outputs a timecode of one minute and 28 seconds (expressed as 00:01:28:00), the slave
device follows it there. If the master player is playing a presentation or has a presentation
cued and has received the TcStart MSVPP command, the LTC counts up from the initial
command. If the master player is paused, the LTC repeats the same value. The active or
static LTC value can be seen as the TC field on the front panel Channel Status screen (see
Channel status menus”).
In an application where other components in the system need LTC, the slave player outputs
the signal on its LTC Out connector.

NOTE: In another application, external show control equipment could provide the LTC
reference. In such an application, both media players are slaved to the show
control equipment.
