RJ-45 connector wiring
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see figure
6
).
•
Crossover cable —
Direct connection between the computer and the media player
•
Patch (straight) cable —
Connection of the media player to an Ethernet LAN
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable that is wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

Remote 1 Port
See “
Programming Guide
“ for definitions of the MSVPP commands (serial commands
to control the media player via this connector).
Snap one of the included ferrite beads on the Remote cable, as close to the unit as
possible.
NOTES:
•
Unlike products that were designed by Extron, former Electrosonic
products use a
male
connector. You may need an adapter.
•
Serial port Remote 1 can be set to ControlMSVPP (control the player),
Passthrough (pass the signals through to a controlled device), or Disabled.
•
The media player can:
•
Operate at 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400,
57600, or 115200 baud rates
•
Use 7 or 8 data bits
•
Use no parity, even parity, or odd parity.
•
Use 1 or 2 stop bits
•
Serial port Remote 2 is for factory use only. The customer or end user
cannot control the player via the Remote 2 port.
