Description
LINK
OFF means no link is present; ON means a link is present.
ACT
OFF means no data is being transmitted or received; blinking
means data is being received or/and transmitted.
3.15.4 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.

E3/T3 cable
Note:
MIM-1AE3 and MIM-1AT3 modules use the same type of cables for connection, which
are called E3/T3 cables in this manual.
3.15.5 Connecting the Interface Cable
Caution:
Some measures have been taken to protect MIM-1AE3 module. To achieve better
lightning protection effects, however, you are recommended to add a special lightning
arrester at the input end of the E3/T3 cable when leading it to the outdoors.
Step 1: Connect the SMB connector of an E3/T3 cable to the Tx port on MIM-1AE3 and
another end to the Rx port on the device to be connected;
