Dual Gigabit Ethernet Ports
Two Gigabit (10/100/1000) RJ-45 Ethernet LAN ports for IP connections. By default, the codec
assumes LAN1 is the primary LAN connection and LAN2 is the backup LAN connection when in
use. If you are only using one Ethernet port, always use LAN1. LED indications allow identification
of LAN speeds as follows:
· 1000 Mbps: Green = Blinking / Orange = Off
· 100 Mbps: Green = Off / Orange = Blinking
· 10Mbps: Green = Blinking / Orange = Blinking
USB Host Port
Rear panel USB 3.0 host port supports record and playback of audio files.
DB-9 RS-232 Port
A nine pin female RS-232 serial connection for local and remote control of equipment at either end of
the link.
