5. ADVANCED USER INTERFACE
Page 121 © 2009 DH Instruments, a Fluke Company
If the optional Ethernet interface is installed, the following two options are displayed.
USB: Indicates both front and back USB ports, not selectable
Ethernet : To view and edit LAN settings (see Section 5.7.9.4).
5.7.9.1 COM1 and COM2
The COMx ports can be set for specific communications settings. The settings
are baud rate, parity, data bits and stop bits. The available options are:
Baud Rate: 1 200, 2 400, 4 800, 9 600, 19 200
Parity: None, Odd or Even
Data Bit: 7 or 8
Stop Bit: 1 or 2
The default is <2400, E, 7,1> for both COM1 and COM2.
Note
The PPC4 looks for an ASCII(13) (carriage return) to terminate a
received command but responds with both and ASCII(13)
(carriage return) and an ASCII(10) (line feed). There are no
options.

5.7.9.2 Command Format
[Settings], <More >>>, <Remote>, Command Format opens the Command
Format screen. The highlighted format is the currently active format.
[Settings], <More >>>, <Remote>, Command Format, Classic selects the Classic
format for commands (see Section 6.4.1)
[Settings], <More >>>, <Remote>, Command Format, Enhanced selects the
Enhanced format (see Section 6.4.2).
Selecting a format resets the IEEE-488 interface and puts it into an idle state.
See also Section 6.4.
5.7.9.3 IEEE-488
The IEEE-488 port’s primary address can be set from 1 to 31 in this screen. The factory
default value is 10. Secondary addressing is not used or supported. This address
must not conflict with the address of any other device on the same IEEE-488 bus.
Note
The receiving terminating character must be a line feed and EOI.
Carriage returns are ignored if received. The PPC4 sends a line
feed and asserts the EOI line to terminate a reply. These
settings are fixed to agree with IEEE Std. 488.2. If the address is
changed, the IEEE interface resets (PON) and becomes idle.
5.7.9.4 Ethernet
[Settings], <More >>>, <Ethernet>, Setting allows selection of DHCP (for
dynamic selection of IP address by the LAN (Local Area Network) or
Manual for user entered IP address.
