4.2 - Asynchronous Mode Configuration
For asynchronous communication, the Asynchronous mode setup parameters differ from the
parameters described in the previous section (sec. 4.1). The figures below display the two set-up
screens for this mode.
From any of the two screens press <F2> (MENU) to go back to the Modes menu screen. To
alternate between these screens use <F1> (BACK) and <F4> (NEXT).
Each parameter is described after the figures. To edit these parameters, place the cursor at
the adequate line and follow the specified instructions.

•
Interface : Determines the interface to be used in the test as RS232, V.35, V.36 or X.21,
using the ← or → keys.
•
Pattern : Determines which pattern will be transmitted and received by the Test Set. The
choice can be done by using the ← or → keys. It is possible to choose among the
following pseudo-aleatory patterns: 2E6-1/ 63, 2E9-1/ 511, 2E11-1/ 2047, 2E12-1/
4095, 2E15-1, 2E20-1 0153, Mark (‘1111’), Space (‘0000’), ALT M/S (alternating ‘1’ e
‘0’), FOX, USER , 7:1 e 1:7 (mark:space). The USER pattern can be user edited, bit-by-
bit. To do this, select the USER pattern and press the DATA key. The editing mode
screen will be displayed. Using the 0 and 1 keys, edit the desired word. To end editing
press <F4> (ENTER). To cancel the editing, press <F1> (EXIT).
•
Polarity : Determines signal polarity. It can be NORMAL or INVERTED. For inverted
polarity every pattern bit value is inverted for transmission and the analysis is adjusted
