Wiring
This topic describes all possible connections to and from the Compact Engine. Depending on the application,
you may need only some of these. Please see
For the initial setup, only ETHERNET (1), CAN (2) and Power (9) are required.
For the audio and GPIO connections, the functionality is defined by the configuration. Therefore, before wiring
these connectors, please refer to the
Compact Engine (front and rear)

ETHERNET (CAT 5e or better)
The ETHERNET port provides a network connection to the Compact Engine control system. This is used to
remotely control crystal from VisTool or Ember+ devices; to update the system firmware and configuration; and
to network crystal to other Lawo systems.
The connection can be made either directly or via a network switch. When connecting via a network, then this
can be shared with other devices, such as in the regular "house network" of a typical broadcast facility. Routers
are permitted as long as the minimum requirements below are met. By using routers, or similar devices, the
latency of the communication will increase. The control network
MUST
meet or exceed the following
requirements:
·
At least 100MBit/s; 1 GBit/s preferred
·
Full Duplex
It is important to keep the control network separate from the streaming network if a RAVENNA IO card is
fitted to an expansion IO slot (5).
For a direct connection, you will need a crossover network cable. For connection via a network switch, use a
straight (1:1) network cable. The cable should be STP-CAT 5e or better with RJ45 connectors.
The port has two LEDs which indicate the following information.
