Network Status
Different promote messages will be provided by DG5000 based on the current
network status.
 Connected: LAN connection is successful.
 Disconnect: LAN connection is unsuccessful.
MAC Address
MAC (Media Access Control) address, also called hardware address, is used for
defining the position of the network device. For a generator, the MAC address is
always unique. It is always used to identify the instrument while assigning IP address
for instrument. MAC address (48 bits, namely 6 bytes) is usually expressed in
hexadecimal format, such as 00-14-0E-42-12-CF.
VISA Descriptor
VISA (Virtual Instrument Software Architecture) is an advanced application
programming interface developed by NI (National Instrument) for communications
with various instrument buses. It uses the same method to communicate with
instruments regardless of the types of the instrument interfaces (GPIB, USB,
LAN/Ehternet or RS232). The GPIB, USB, LAN/Ethernet or RS232 instrument to
communicate with VISA is called “resource”.
VISA descriptor is the resource name and describes the accurate name and location of
the VISA resource. If LAN interface is currently used for communication with the
instrument, the VISA descriptor is TCPIP0::172.16.3.81::INSTR.
IP Configure Mode
IP configure mode could be DHCP, AutoIP or ManualIP. If the current network is
disconnected, there will be nothing to display behind “IP Configure Mode:”. In
different IP configure modes, the configure mode for LAN parameters such as IP
address will be different.
