Extend Header Selection
Jumper W11 (D11/41) controls the extend header bit, which when set, al-
lows the LINK module to extend the number of bit-synchronous characters
in the header.
Jumper OUT = Normal header (default)
Jumper IN = Extended header
Extend ACK Timeout Selection
The extend ACK timeout bit forces the LINK module to increase the time-
out period for an ACK return. The jumper representing this bit is W12
(D12/42).
Jumper OUT = Short timeout (default)
Jumper IN = Long timeout
Disable Arbitration Selection
The disable arbitration selection bit when set, defeats the normal arbitra-
tion sequence and allows the LINK module to transmit after waiting only
one basic Quiet Slot DELTA Time. The jumper that controls this bit is
W10 (D10/40).
Jumper OUT = Normal CI arbitration (default)
Jumper IN = Disable normal CI arbitration
