5.3.20 Communications Monitor
When the Communications Menu is displayed, pressing the Communications
monitor key accesses the Communications monitor display, shown in figure 5-26. It
may also be accessed via the RS232 Settings and USB Status menus.
The monitor is useful when attempting to establish communications via the computer
interfaces for the first time, or if a problem is suspected.
The Input side of the display shows all of the characters that have been received from
the interface, whether valid or not. The Output side of the display shows all the
characters that have been generated by the instrument and sent to the interface.
If characters received do not match those sent by the controlling computer then this
indicates that an error has occurred either in the host computer or interface cable. If
the interface cable is known to be good, then re-check either the RS232 or USB
communications settings.
CLEAR SCREEN
The input and output displays scroll once they are full so that they always display the
most recent characters received and sent. Pressing the Clear Screen key clears both
areas.
Pressing the Previous Menu key returns control to either the Communications menu
or the USB Status menu, or the RS232 Setting menu, depending on how the
Communications Monitor display was accessed.
Pressing the Previous Menu key returns control to the Configuration Menu.
5.3.21 Options Menu
When the Configuration menu is displayed, pressing the Options key accesses the
Options Menu, shown in figure 5-27.
