15.5 Controlling the Instrument with Command Communications (LAN)
332
You can control the instrument remotely over the communications interface (LAN).
• For details, see the communications related documentation on the supplied application
disc.
• Before using command communications, the LAN settings and connection must have
been established properly.
See: LAN"15.1"(p.314)
15.5 Controlling the Instrument with Command
Communications (LAN)
In an environment where noise from inverters or similar devices is present,
errors may occur when controlling the instrument remotely. Take care to ensure
that the environment is not subject to excessive noise.
About Setting Items
Delimiter The Delimiter item specifies LF or CR+LF as the newline delimiter in command response messages. The
instrument understands all three settings: LF or CR+LF.
Header Use for control of communications commands.
The Header item specifies whether to prefix headers to command response messages.
For more information about commands, refer to the Communications operation manual on the supplied CD.
Command Port
(Port number)
The instrument uses the TCP/IP protocol for communications. TCP/IP allows communicating devices to es-
tablish multiple connections, which are distinguished by port numbers.
By default the instrument uses port numbers 8800 to 8809.
•8800 to 8801 reserved
•8802 (instrument is server): For communications command control
•8803 to 8809 reserved
Normally these ports do not need to be changed. You can change them if certain ports cannot be used for
security reasons, or if certain ports are not available on the communicating PC. Set only the most significant
three digits. The least significant digit (0 to 9) is used by the instrument, or reserved for use by the instru-
ment.

15.6 Operating the instrument remotely and acquiring data by using Model 9333 LAN Communicator
334
Model 9333 LAN Communicator, which is the optional communication program for PCs, enables the
PC to control the instrument remotely and to store data directly.
Additionally, Model 9333 enables waveforms to be printed from a printer connected to the PC.
