• Error/Condition: While attempting to connect a computer via null
modem cable to an FX16, the dialer retrieves Error 619.
• Problem: If an attempt is made to connect to an FX16, which does
not have a Web site defined in its application, the FX16 does not

Dialer Retrieves Error 777
• Error/Condition: While attempting to connect a computer via null
modem cable to an FX16, the dialer retrieves Error 777.
• Problem: The RS-232 card is not recognized properly.
• Solution: There are two possible conditions triggering this problem:
• The RS-232 communication card is still configured as N2 card.
A power cycle may not have been performed following an
application download. A power cycle is required to reconfigure
the communication card. In this case, the solution is to power
cycle the FX16.
• The RS-232 communication card is performing an outgoing
notification so that the line is busy. In this case, the solution is to
retry at a later time.
