If the DUT Definition is a DUT Profile , the screen sets up with blank
information in the serial number and identification fields. At least one of
these fields must be completed prior to closing the window. This window
displays regardless of the state of the setup DUT option in
[Tools] ,
[Options] , [Initialize Test] , <Select DUT> (see Section 11.5).
•
If the DUT read or set type is RS-232 or IEEE-488, the default
communications settings for the selected interface type display in the
interface field (see Sections 8.5.8,8.5.9). If the interface is IEEE-488, enter the
numerical IEEE-488 address. If the interface is RS-232, click the field to
select the RS-232 settings. When both set and read share the same
interface type, a change to the read interface automatically makes the same
change to the set interface. Changes to the set interface do not automatically
update the read interface. It is therefore possible for the set and read interfaces
to be different. This is an atypical use of this feature but it is supported.
•
If the DUT read or set type is neither RS-232 nor IEEE-488, the interface
description contains the text representing the type of interface to use. This can be
<Voltage/Current> , <Frequency> , or <Manual> .
If the DUT is connected to the molbox’s RS-232 COM2 port, use the <Ref COM2>
selection at the bottom of the Com Port drop down list. COMPASS automatically
handles the necessary command formatting to pass commands through the
COM2 port.
When using the <Setup DUT ID/Interface> screen, keep in mind that DUT read
and set types refer to the manner in which data will be gathered from the DUT.
DUTs with electrical outputs are read with a DMM and the read type is
Voltage/Current (it is not the interface on the DMM such as RS-232 or IEEE-488).
Only DUTs read or set directly by RS-232 or IEEE-488 interfaces are
considered to use RS-232 or IEEE interface (see Sections 8.5.8, 8.5.9).
