Configuring the Card
Configuring the Card Using iosetup
After installation of the driver software and loading of the t81488 kernel module
(handled automatically by the RPM package), the SICL iosetup command must be
executed to configure the TAMS card as a SICL instrument card. See the man page on
iosetup (1M).
The t81488 driver is implemented as a custom TULIP driver. Therefore, the system
does NOT need to be rebooted after changing the configuration using iosetup.
However, the SICL iclear command should be used after making changes to ensure
that the configuration changes have taken effect. See the man page on iclear (1).
The following information must be supplied by the user during the iosetup process:
1. Logical Unit #: the user must supply a logical unit number for the TAMS card that is
distinct from all other logical unit numbers currently configured under SICL.
2. Symbolic Name: the user must supply a symbolic name for the TAMS card that is
distinct from all other symbolic names currently configured under SICL.
3. Rotary Switch: the user must specify the setting of the rotary DIP switch on the
card.
4. HP-IB Address: the user must specify the HP-IB bus address that the TAMS card is
to use on the HP-IB bus. This value must not be the same as any other device
connected to the HP-IB cable. It may be the same as other HP-IB interface cards in
the computer, so long as those other cards are not attached to the card via the HP-IB
cables. If the TAMS card is set up as a system controller, it is traditional to give it
HP-IB bus address 21. This is not required, but does serve to reduce confusion.
5. System Controller: the user must specify “Yes” if the TAMS card is to be used as
the system controller. The value “No” will cause the card to function as a non-
system controller.
6. Short T1 Time: the user must specify the IEEE-488.1 T1 delay value for data
transactions in nanoseconds. Reasonable values are an integer between 350 and
1100. For maximum data throughput a value of 350 can be used provided the
system meets the following constraints specified in section 5.2.3 of the IEEE-488-
1987 standard:
a) All devices expected to talk at higher rates should use a minimum T1 value of
350ns.
