AMX Modula Instruction Manual page 33

Important: If an enclosure in a linked system is down (due to power failure, etc.), it may need to be
disconnected from the remaining enclosures in order for the rest of the system to continue working.
Linking a Modula to a Modula, Epica-128, or Epica-256
A Modula can be directly linked to another Modula, an Epica-128, or an Epica-256 via the Ethernet
linking ports.
The total distance between the two linked enclosures cannot exceed 10 ft. (3.05 m).

Modula to Modula or Epica-128 or Epica-256
Important: 50-ohm termination connectors are required on the open ends of all T-connectors when
linking enclosures.

FIG. 12
Modula linked to Modula
To link a Modula to a Modula, Epica-128, or Epica-256:
1.
Fasten T-connectors to the Ethernet (BNC) linking ports on both enclosures.
2.
Fasten 50-ohm termination connectors to the T-connectors on both enclosures.
3.
Attach an RG-58 coax cable from the open end of the T-connector on the first enclosure to the open
end of the T-connector on the second enclosure.
4.
If applicable, additional 10Base-2 enclosures can be daisy-chained off either enclosure
(see page 29).
When power is applied, the Comm (Communication Status) indicator at the top of the CPU board
illuminates indicating traffic between enclosures.
