Serial Operation; Ieee-488 Communication (Optional); Setup - Fluke 7008 User Manual

10.1.2.2 Sample Period
The sample period is the next parameter in the menu and prompted with
"SAmPLE". The sample period is the time period in seconds between
temperature measurements transmitted from the serial interface. If the sample
rate is set to 5 for instance then the 7008 will transmit the current measurement
over the serial interface approximately every five seconds. The automatic
sampling is disabled with a sample period of 0. Press "SET" to choose to set the
sample period. Adjust the period with "UP" or "DOWN" and then use "SET" to set
the sample rate to the displayed value.
10.1.2.3 Duplex Mode
The next parameter is the duplex mode indicated with "dUPL". The duplex mode
may be set to half duplex ("HALF") or full duplex ("FULL"). With full duplex any
commands received by the thermometer via the serial interface will be
immediately echoed or transmitted back to the device of origin. With half duplex
the commands will be executed but not echoed. The default setting is full duplex.
The mode may be changed using "UP" or "DOWN" and pressing "SET".
10.1.2.4 Linefeed
The final parameter in the serial interface menu is the linefeed mode. This
parameter enables ("On") or disables ("OFF") transmission of a linefeed
character (LF, ASCII 10) after transmission of any carriage-return. The default
setting is with linefeed on. The mode may be changed using "UP" or "DOWN"
and pressing "SET".

10.1.3 Serial Operation

Once the cable has been attached and the interface set up properly the controller
will immediately begin transmitting temperature readings at the programmed rate.
The set-point and other commands may be sent to the bath via the serial
interface to set the bath and view or program the various parameters. The
interface commands are discussed in Section10.3. All commands are ASCII
character strings terminated with a carriage-return character (CR, ASCII13).

10.2 IEEE-488 Communication (optional)

The IEEE-488 interface is available as an option. Baths supplied with this option
may be connected to a GPIB type communication bus which allows many
instruments to be connected and controlled simultaneously.

10.2.1 Setup

To use the IEEE-488 interface first connect an IEEE-488 standard cable to the
back of the bath. Next set the device address. This parameter is programmed
within the IEEE-488 interface menu.
