Configuration
Setting Configuration Values
Hardware Address
(MAC) (cont’d) N/A The hardware address value cannot be set or changed with
Telnet configuration of the LAN/GPIB Gateway. However, the
hardware address value must be specified and set when using
the BOOTP or the BOOTP with TFTP configuration method.
Hostname
E2050
This value configures the Internet domain name for the LAN/
GPIB Gateway. This name is used in some error and status
messages, but is not a required configuration setting. The
maximum length of the
hostname
value is 35 characters.
HP-IB Address 21
This value configures the GPIB bus address. This address is
used when transfers are made on the GPIB bus. A SICL client
application can change this value by using the SICL function
IGPIBBUSADDR
. The GPIB address value can be any number
0
through
30
.
HP-IB Interface
Name
hpib
This value is the symbolic name of the GPIB interface in the
LAN/GPIB Gateway. It is used in a SICL client application’s
iopen
operation to symbolically reference the GPIB interface
in the Gateway. The maximum length of the GPIB interface
name is 15 characters.
If VXI-11 (TCP/IP Instrument Protocol) is used, the name must
be changed to
gpib0
. Also, for VISA LAN client, this name
must match the name set in the IO Config utility.
HP-IB Logical Unit
7
This value is the interface logical unit number of the GPIB
interface in the LAN/GPIB Gateway. It may be used in a SICL
client application’s
iopen
statement to uniquely identify the
GPIB interface in the Gateway. The GPIB logical unit value can
be any number
1
through
255
.
I/O Timeout
120 sec
This value sets the server I/O timeout in seconds. It configures
the Gateway to use an I/O timeout of the specified amount of
seconds if the client requests a timeout of infinity. If
0
is
specified for this value and the client requests infinity, the
Gateway will use a timeout of infinity as requested.
This timeout value may be used to ensure that the Gateway
does not wait indefinitely for an I/O operation. It also allows the
Gateway to detect certain network events (such as when a
client connection is dropped) that may otherwise go
undetected. If the Gateway detects such a condition, it will
release any resources, such as locks, associated with the
client.
