Connection of LTMT Main Unit to LTMT Expansion Module
The maximum number of LTMT expansion module that can be connected to one LTMT main unit is five modules.
Different types of the LTMT expansion module can be connected to one LTMT main unit. The maximum number of each LTMT expansion module that can be connected to one LTMT main unit is given in the following table:
|

The connection between LTMT main unit and other LTMT expansion module is in daisy chain configuration. The LTMT expansion module has two RJ45 port. Both the ports can work as either input port or output port.
To connect the LTMT main unit to the LTMT expansion module:
-
Using the LTMT9RJ401 or LTMT9EX10 cable, connect the cable from EXP port of the LTMT main unit to one of the RJ45 port of the first LTMT expansion module.
-
Connect the other RJ45 of the first LTMT expansion module to one of the RJ45 port of second LTMT expansion module.
-
Repeat step 2 for the remaining LTMT expansion modules.
