Figure 2. Example 1, DUT Read Command Setup
Setting up the <Set Point Type> is similar to setting up the DUT <Output Type> .
On the [Set] tab, first select RS-232 as the <Set Point Type>, then enter the
RS-232 settings for the DUT: 9600,E,7,1. Then click the <Edit> button next to
the <Set Commands> list to display the remote command setup form. Insert the
(02H) control code as previously described. Now enter the DUT Set command,
“01STD” next to the control code. Instead of ## for the numerical set value,
either type or drag and drop the
<Set Unit Variable> at the end of the set
command. This tells COMPASS where to place the numerical flow target value.
Save this DUT using the <Save> toolbar icon. The RS-232 communications port has
not been entered. This selection occurs as one of the last steps in test initialization,
<Setup DUT(s) - Data Acquisition> (see Section 7.2.1.5).
5.1.1.2 SET UP A molbox AS THE REFERENCE
Use [Setup] , [Hardware] to open the Hardware Definition screen (see Section 10.3.3).
Select the [Reference] tab and check to see if the desired molbox is already in
the list. If so, verify that the remote settings are correct and close the display.
Otherwise press
<New> to create a new reference (see Section 10.3.3). Select
DH Instruments as the manufacturer and molbox1 (or RFM) as the model reference.
Then enter all other support information. For this example, the molbox will use
an IEEE-488 interface. The IEEE-488 address of the molbox can be determined
using the molbox’s front panel
[Special] key (see the molbox Operation and
Maintenance Manual). In this example, 10 is used. Press <OK> to save this
Reference Definition.
