29 Modula Instruction Manual
Linking a Modula to Multiple 10Base-2 (BNC) Enclosures
Important: Always attach 50-ohm termination connectors to the open ends of the T-connectors on
the Media Converter and on the last enclosure on the coax cable run in multiple-enclosure systems.
A Modula can link to multiple BNC enclosures in a daisy chain with RG-58 coax cable (FIG. 14). The
total distance between the two end termination connectors in a multiple-enclosure system with BNC
ports cannot exceed 10 ft. (3.05 m).
To link a Modula to multiple enclosures with BNC ports:
1. Fasten a T-connector to the Ethernet (BNC) linking connector on the Modula’s CPU.
2. Attach a 50-ohm termination connector to one end of the T-connector.
3.
Fasten T-connectors to the Ethernet (BNC) linking ports on the remaining enclosures.
4.
Attach an RG-58 coax cable from the open end of the T-connector on the Modula to the
T-connector on the next enclosure.
5. Link remaining enclosures in a daisy chain using RG-58 coax cable attached to the T-connectors.
6.
Attach a 50-ohm termination connector to the open end of the T-connector on the last enclosure in
the daisy chain.
When power is applied, the Comm (Communication Status) indicator at the top of the CPU board
illuminates indicating traffic between enclosures.
