Model 466-1 Adapter
26 VMEbus Adapter Card Configuration
4.4 System (SYS) Jumpers
The
SYS
jumper block is shown here as the card is shipped:
Jumper IN: -------
Jumper OUT:
1
Jumper if the Address Modifier Register is used.
2
Jumper if this card is a "transmitter".
3
Jumper for local vector.
4
Jumper if this card will drive VME SYSCLK.
5
Jumper if this card will drive VME SYSRESET.
6
Jumper if this card will detect bus timeouts.
7
-------
Jumper for indivisible RMW enable.
ADDRESS MODIFIER REGISTER (jumper 1): When this jumper is OUT,
the address modifier presented to this adapter card comes from the default
values sent by the other adapter card. When this jumper is IN, the address
modifier presented to this adapter card comes from the Address Modifier
Register on this adapter card. If the jumper is OUT, a CSR bit can also enable
use of the Address Modifier Register.
TRANSMITTER CARD SELECTION (jumper 2): This jumper is IN when
this adapter card requires command of the adapter cable (to be a cable
transmitter). It does not exclude the other adapter card from also being a
cable transmitter.
LOCAL VECTOR (jumper 3): When jumper 3 is IN, the interrupt vector for
all interrupts presented by this adapter card to its VMEbus comes from the
adapter Local Interrupt Vector Register. If this jumper is OUT, only IRQ1
and IRQ2 use the Local Interrupt Vector Register. IRQ3 - IRQ7 (transmitted
from the remote chassis) cause an interrupt acknowledgment sequence to be
sent transparently to the remote chassis where it reads back the vector in that
chassis.
