12. ETH A connector. It is used to connect the unit to the IP
network (see section 6.1).
It has 2 LED indicators:
Green LED: On indicates connection to the network.
Flashing indicates sending or receiving data.
Yellow LED: Network speed. On indicates a network speed
of 100Mbps. Off indicates a network speed of 10Mbps (it is
highly recommended to use a transmission speed of 100
Mbps.
13. ETH B connector. Used in a redundant network as a
secondary connection to the IP network (see section 6.2).
14. Micro SD memory (16 GB). Stores local pre-recorded
messages.
