Head-end Installation ER8400:
The ER8400C is a wall mount unit. When mounting the unit be sure to leave space
on the sides for airflow into the cooling fans and some space on bottom for the power cord.
The BNC ports are designed for connection with standard coaxial cables. These BNC ports are the EtherStretch
ports. The EtherStretch ports are 10/100Mb speed and will run at the highest possible speed given the wire condi-
tions. The ER8400C works like a standard network switch for Ethernet devices but over coax. For long runs of up to
500 meters it is combined with the ET1500C Transmitter to provide a network link. This system normally operates at
100Mb but can adjust for varying wire length and conditions. We refer to the cable between the Head-end and the
transmitter as the Link cable. The speed of the connection is indicated on the LED panel of the unit. A transmitter
must be connected at the far end of the Link cable for the connection speed to be indicated.
