XTC/3 Operating Manual
2.3.4 RS-232C Communications
RS-232C serial communications is standard in XTC/3. RS-232C is used
to remotely control or monitor XTC/3.
Optional Windows
®
compatible software, INFICON PN 780-032-G1, provides for
parameter entry, recipe storage, data logging and monitoring as well as Start, Stop
and Reset control.
An industry standard 9-pin D-Sub connector is required for the host computer side
connection. The permissible length of the cable is governed by published
standards.
The controller interface operates as DCE (Data Communication Equipment),
hardware handshaking is not supported.
Pin assignments are for the XTC/3 connector. In most cases, a straight-through
serial cable (not a null modem cable) with a female 9 pin D connector on the PC
end and a male 9 pin D connector at the XTC/3 end will work, however,
only pins 1, 2, 3 and 5 are used.
2.3.5 TCP/IP Communications Connection (Optional)
NOTE:
This section applies only if the optional TCP/IP interface
has been installed.
The TCP/IP interface option for XTC/3 accepts a standard ethernet TCP/IP
communications connection. If XTC/3 is directly connected from a stand-alone
computer, the ethernet cable should be a crossover cable unless the PC has the
ability to dynamically reconfigure itself. Static addressing is supported,
DHCP is not supported.
2.3.5.1 Network Connection
If XTC/3 is connected through a network or hub connection, a standard straight
ethernet cable is required.
