2.2.4 Backplane buses
All of the inserted modules receive their voltages and exchange data via 2
parallel backplane buses:
 L bus („local bus“, below)
 C bus („communications bus“, top)
The bus uses the daisy chain principle where a CPU module accepts the
token signal and then transfers it to the next CPU module.
Thus, a daisy chain jumper must be inserted in all backplane bus PC board
slots where there is no CPU module (or EPx signal processor module).
If another module is inserted, the jumper is unimportant.
The jumper must be correctly inserted up to the last (righthand) CPU
module.
A jumper is required if a module is not located at a connector.
The two pins to insert the jumpers are located to the right of the backplane
bus connector (96-pin socket connector).
All of the jumpers are inserted when the equipment is shipped.
