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

section 2.3.4 on page 2-11

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

section 5.2

. See

section 2.3.5 on page 2-11

and

section 2.3.5.1
