LED Description
LINK
z
OFF means no link is present;
z
ON means a link is present.
ACT
z OFF means no data is being transmitted or received.
z Blinking means data is being received or/and transmitted.
Interface cable
External ports provided by MIM-1AE3 are two SMB sockets respectively functioning as Tx end and Rx
end for transmitting data and receiving data. The ports work in 75-ohm unbalanced transmission mode
and are connected to the peer device using a pair of 75-ohm unbalanced coaxial cables. Several cable
length options are available.
