Data Bits
Data bits refers to the number of bits that make up an ASCII character that is transferred
between units. Most METTLER TOLEDO equipment communicates using 7 data bits.
1. At the Data Bits? prompt, select 7 or 8 data bits.
Parity
Parity is an error checking mechanism for each byte.
1. At the Parity? prompt, select the desired option. Parity options include:
• Even—the terminal sends an even number of logic 1 data bits. If the sum is
odd, an eighth logic 1 bit is added for an even total. If the sum is even, a 0 bit
is included to leave it unchanged.
• Odd—the terminal sends an odd number of logic 1 data bits. If the sum is even,
a logic 1 bit is added for an odd total. If the sum is odd, a 0 bit is included to
leave it unchanged.
• None— for use with eight data bits.
Flow
The flow parameter lets you control data flow from the selected port to a peripheral
device that supports XON/XOFF data flow. If enabled, the JAGXTREME terminal monitors
the XON/XOFF characters and controls data flow to help eliminate buffer overflow
problems that can cause printing errors.
1. At the Flow? prompt, select the desired data flow option:
• None— The JAGXTREME terminal does not respond to XON/XOFF.
• XON/XOFF— The JAGXTREME terminal stops transmission on receipt of the
XOFF character (13h) and resumes on receipt of the XON character (11h).
Remote
If you select Remote, the following steps will identify and list remote JAGXTREME
terminals with which your terminal can communicate through its serial ports.
1. At the Node? prompt, select the remote terminal with which you will communicate.
Five are available; the terminal you are configuring is excluded. Terminal numbers
are determined by the Ethernet jumpers on the Controller board.
2. At the Assign Prt? prompt, select the COM port through which communication will
take place. COM1, 2, 3 and 4 are available.
Add a Connection
The JAGXTREME terminal is programmed at the factory for COM1 to output scale 1 data
on demand. COM2 is not configured at the factory. Before adding connections, METTLER
TOLEDO recommends deleting the existing COM1 connection.
1. Press ENTER at the Add Connection? prompt.
2. At the Type? prompt, select the type of serial connection for the scale:
• Serial Out
• CTPZSU In
• Bar Code In
• Keyboard In
• Cust Print from template (1 through 5)
• TDC3000
COM1 and COM2 always have 1
stop bit.
XON/XOFF requires character input.
It will only work if the serial port has
no other input connections. For
example, you cannot configure
CTPZSU In.
The remote terminal’s
communication parameters, such
as baud rate, are configured in the
remote terminal. You cannot
configure remote communication
parameters through this program
block.
If you see the conflict exist error,
you must first delete the existing
connection before adding a new
connection.
