9-pin male D connectors for two FIP bus cables. A bus can be disconnected
from the module without disturbing the continuity of the bus. The second bus is
a backup for the first bus; its use is optional.
Connector for a FIP synchronization cable. It requires a mating connector such
as Molex #39-01-4031. The synchronization capability is not used in a Series
90-70 PLC application.
The lug below the Synchro connector is used for the module ground wire
(provided). The other end of the ground wire must be connected to the mounting
bolt on the lower left corner of the baseplate and to chassis ground.
The green Carrier Detected LEDs indicate the presence of a carrier-detect signal
on their respective channels.
The red Transmission Enabled LEDs indicate the module is generating
transmissions on their respective channels.
