The hardware path for the ACC card can be found by entering:
ioscan -f | grep ACC
Some typical examples are as shown below.
Example #1 The following ioscan -f output denotes a standard
HP-PB system with no bus converter and the 8-channel
ACC card has a card address of 4:
Class I H/W Path Driver S/W State H/W Type Descr.
nacc 0 4 nacc0 CLAIMED INTERFACE ACC MUX
The corresponding mux statement in the ttgen
configuration file should be:
Mux 0 0:4 /opt/acc/z7340a/sample.zabs.
The zero in the "0:4" term denotes no bus converter.
The corresponding device file will be /dev/zmuxb0s4,
where the minor number is 0x400004.
Example #2 The following ioscan -f output denotes a standard
HP-PB system with bus converters. The 8-channel ACC
card has a bus converter address of 56 and a card
address of 48:
Class I H/W Path Driver S/W State H/W Type Descr.
nacc 0 56/48 nacc0 CLAIMED INTERFACE ACC MUX
The corresponding mux statement in the ttgen
configuration file should be:
Mux 0 56:48 /opt/acc/z7340a/sample.zabs.
The corresponding device file will be
/dev/zmuxb56s48, where the minor number is
0x400e30.
