XTC/3 Operating Manual
5.1.2 Physical Connections
Two types of data communications hardware ports are available.
Standard equipment includes a bit serial RS-232C port. Optionally, a TCP/IP port
may be added. Generally speaking, both the host and server must have the same
form of communications equipment and complementary set-up. For serial
communications, baud rates must match and so must the data word format.
The word format for bit serial lines (RS-232C) is comprised of ten signal bits —
eight data bits, one start bit, one stop bit and no parity. The eight data bits comprise
a byte of information or character whose ASCII value ranges from 0 to 255.
Both RS-232C and TCP/IP ports can be used simultaneously.
5.1.3 RS-232C Serial Port
RS-232C serial communications are accomplished through an industry standard
9-pin female connector found on the rear panel of XTC/3. A mating male connector
is required for attachment of a host interface. The host and XTC/3 can be
separated by up to fifty feet using multiconductor shielded data cable.
XTC/3 is configured as DCE or Data Communications Equipment. The PC or other
host device should be set for no parity, 8 data bits and 1 Stop bit. Hardware
handshaking is not supported in XTC/3. Refer to
for
cable connections and pin-outs.
5.1.4
TCP/IP Ethernet Port
XTC/3 communicates via TCP/IP on TCP port number 2101 and uses a variety of
binary commands as described at
for the appropriate ethernet cable type and
for determining or changing the IP address. The interface supports static
addressing, DHCP is not supported.
5.1.4.1 Network Connection
If XTC/3 is connected through a network or hub connection, a standard straight
ethernet cable is required.
