Communication Interruption with XBT N200 or XBT N400 Terminals
A communication interruption may have occurred if ????? is displayed rather than
any values, or the connection popup remains on the display unit. If you are using an
XBT N200 or an XBT N400 terminal, it may be caused by the cabling because
different cables are required for the different terminal versions. Use the cables as
shown in the table below. If you are using other terminals or the condition still
persists with these cable, refer to section Troubleshooting, page 156 or to the
manual describing the protocol you are using for more information.
