4.5.2
<Spec>, <Remote>
PURPOSE
To configure the PPC4 COM1, COM2 and IEEE-488 (GPIB) or Ethernet communication
ports. To test COM1 and COM2 communications. To select remote programming
communications format (see Sections 3.2.24 and Section 6.3.1).
OPERATION
To access the communications settings, select
<Spec>
,
<Remote>
.
Choice include:
<COM1>
To view and edit COM1 settings (see Section 4.5.2.1).
<COM2>
To view and edit COM2 settings (see Section 4.5.2.1).
<IEEE>
To view and edit IEEE-488 settings (see Section 4.5.2.2).
<Format>
To select remote programming command format (see Section 4.5.2.3).
<RS232test>
To run the COM1 and COM2 communications test (see Section 4.5.2.4).
<Ethernet>
To view and edit LAN (Ethernet) settings (see section 4.5.2.5).
4.5.2.1 <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
1 200, 2 400, 4 800, 9 600, 19 200
Parity
None, Odd or Even
Length
7 or 8
Stop Bit
1 or 2
The default is <2400, E, 7, 1> for both COM1 and COM2.
The user can also specify one or two termination characters as well as define
these characters. These are referred to as “Term1” and “Term2”. These define
the characters that mark the end of commands that are sent to the PPC4. 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 other options.
4.5.2.2 <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.
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 you
change the address, the IEEE interface will reset (PON) and become idle.
4.5.2.3 <Format>
<Spec>
,
<Remote>
,
<Format>
allows the remote program command syntax to
be selected. The cursor is on the active format. Select
<Classic>
to activate the
classic command format or
<Enhanced>
for the enhanced format.
Selecting a format resets the IEEE-488 interface and puts it into an idle state.
