Specifications

Communication

■ GPADR: gives the device address to be used for GPIB (IEEE 488)

communication,

default is 4

also accessible as GPIB Address parameter, ID 0x11000900

■ IPADR: the first four portions specify the default IP address for

TCP/IP communication, the last portion specifies the default port to

be used,

default is 192.168.168.10:50000

also accessible as IP Address parameter, ID 0x11000600

Note: While the IP address can be changed, the port must always be

50000!

■ IPSTART: defines the startup behavior for configuration of the IP

address for TCP/IP communication,

default is 1 = "use DHCP to obtain IP address"

also accessible as IP Configuration parameter, ID 0x11000800

■ IPMASK: gives the IP mask to be used for TCP/IP communication,

default is 255.255.255.0

also accessible as IP Mask parameter, ID 0x11000700

■ MACADR: is the unique address of the network hardware in the

E-517, read-only, example:

0-d0-c9-a7-1f-86

also accessible as MAC Address parameter, ID 0x11000B00

NOTES

A TCP/IP connection will fail if no DCHP server is present but the

startup behavior for IP address configuration is set to "use DHCP to

obtain IP address, if this fails, use IPADR" (IPSTART = 1). The E-517

will use the address given by IPADR only if IPSTART = 0.

If the IP address for the current TCP/IP connection was obtained from

a DHCP server, this address is not reflected in the response to the

IFC? command.

The currently active RS-232 baud rate and GPIB (IEEE 488) address

can also be checked/set on the E-517 front panel in the

COMMUNICATION display screen (p. 21). This screen can be

accessed by the trackball (p. 22). The front panel settings correspond

with the communication parameter settings described above.
