Ethernet Interface Functions and
Specifications
When using a WT1600 with ROM version 2.01 or later, you can control the WT from a
PC using Ethernet communications. Details about specific functions and how to enter
settings are provided below.
Receiving Function
You can specify the same settings as those specified by front panel key operations.
Receives output requests for measured and computed data, setting parameters of the
panel, and error codes.
Sending Function
Measured/computed data can be output.
Panel setup information and the status byte can be output.
Error codes which have occurred can be output.
Ethernet Interface Specifications
Electrical and Mechanical Specifications:
IEEE802.3 Compliant
No. of simultaneous connections:
1
Port No.:
10001/tcp
For other specifications, see section 17.13, “Ethernet Interface (Option)” in the WT1600
Digital Power Meter User’s Manual (IM760101-01E).
Switching between Remote and Local Mode
When Switched from Local to Remote
Remote mode is activated when the :COMMunicate:REMote ON command is received
from a controller while local mode is active.
• The REMOTE indicator is turned on.
• All front panel keys except LOCAL can no longer be operated.
• Settings entered in local mode are retained even when switching to remote mode.
When Switched from Remote to Local Mode
Pressing LOCAL in remote mode puts the instrument in local mode. However, this is not
possible when the :COMMunicate:REMote ON command is received from the computer
while Local Lockout mode is active. Local mode is activated when the
:COMMunicate:REMote OFF command is received regardless of Local Lockout.
• The REMOTE indicator is turned off.
• All front panel keys are operative.
• Settings entered in remote mode are retained even when switching to local mode.
Note
The Ethernet interface cannot be used simultaneously with other communications interfaces (GP-
IB or serial (RS-232)).
User Verification Function
You must enter the user name and password to access the WT from a PC using the
Ethernet interface. The user name and password for accessing the WT can be specified
in the User Account screen under the MISC menu. For details, see “Ethernet Control
Settings” below.
