Host Communications
The marking system software allows you to configure
communication parameters to transmit and receive data to and
from a host computer. To provide maximum integration
flexibility, the system software supports RS-232 serial interfaces
and Ethernet TCP/IP interfaces. The system software also
provides two protocol choices: Programmable Protocol and
Extended Protocol.
RS-232 Interface. The serial (RS-232) communications
interface is most often used with remote devices such as host
computers, terminals, or bar code scanners. The RS-232
interface supports both Telesis Extended Protocol and Telesis
Programmable Protocol.
TCP/IP Interface. The Ethernet (TCP/IP) interface is most
often used with host computers communicating over a local area
network (LAN).
The Port parameter identifies the host computer socket that is
assigned to the marking system. If more than one marking
system is installed in a network configuration, each system must
use a separate and unique port number. The Address parameter
identifies the IP address of the host computer. The marking
system software supports both fixed addressing and dynamic
addressing.
Programmable Protocol. Use this protocol where very simple
one-way communications are required (such as with bar code
scanners). Programmable Protocol provides no error checking or
acknowledgment of the transmitted data. Note that XON/XOFF
Protocol applies even when Programmable Protocol is selected.
Starting Character specifies where the software begins to
count character positions. This number must be entered in
decimal format (e.g., "2" for ASCII Start of Text "STX").
Terminating Character identifies the end of transmitted
string (usually "13" for ASCII carriage return character).
Character Position counted from the starting character
ignoring all characters preceding it.
Character Length accepts variable length messages (if set
to 0) or messages of a pre-specified, fixed number of
characters.
Ignore Character identifies the character to ignore when sent
from the host (usually "10" for ASCII line feed character)).
Message Type allows message-type recognition which
defines how the marking system will use data it receives from
the host.
1 Message type 1 overwrites the first line of the first text
field with data extracted from the host
P Message type P loads a specific pattern identified by
data extracted from host
Q Message type Q updates the text in the first query
buffer with data extracted from the host
V Message type V updates the first variable text flag
found in the pattern with data extracted from the host
0 Message type 0 (zero) indicates that host will provide
message type, field number (if applicable), line number
(if applicable), and data; delegates message type
selection to the host on message-by-message basis.
The host message must use the format:
Tnn<string>
where:
T = 1, P, Q, or V to indicate message type
nn = two-digit field number or query text
buffer where data will be placed.
Note: Not used with Message Type
P.
<string> = For Message Type P, indicates the
pattern name to be loaded.
For Message Types 1, Q, or V,
indicates the data to be inserted into the
field or the query text buffer, as
applicable.
