Balance Port (RS232).
Accesses sub-menu, Balance
Port Communications.
Balance Type. This key toggles through the
available balance templates.
Customize Balance Settings. This key leads
to a submenu that allows the balance template
and related port frame parameters to be altered
as required.
The Customize Balance Settings sub-menu sets
the communication parameters for the RS232
port used for the balance port. Standard options
for data bits, parity, stop bits, handshaking, baud
rate and balance type are provided to match any
devices that might be connected to these ports.
Number of Data Bits. Standard options for data
bits. Toggles between 7 and 8.
Parity. Standard options for parity. Choose from
None, Odd or Even.
Number of Stop Bits. Standard options for stop
bits. Toggles between 1 and 2.
Handshaking. Standard options for handshaking.
Choose from Xon / Xoff, RTS/CTS and None.
Baud Rate. Standard options for baud rate.
Choose from 19.2K , 9600, 4800, 2400, 1800,
1200, 600, 300, 150, 134.5, 110, and 75.
Data Characters from Balance. This setting is only
used when the generic balance format is selected.
This value determines the number of numeric data
characters (0-9 . + -) to accept. Any additional
characters after this value and before the string
terminating are discarded.
Data Precision. This key allows the user to
establish the number of digits to the right of the
decimal point that are passed from the balance
handler.
Transfer Timeout (seconds). This value
determines how long the interface will wait before
giving up on a weight transfer. The value is
entered in seconds.
Balance Handler Strings. This key leads to a
submenu that allows balance template to be
customized for unique balances or needs.
Log Balance to Display. This button will direct
the incoming data stream from the balance to a
display buffer. This function can be used to
determine the data format from an unknown
balance type. The display buffer is 40
characters in length. The balance must be
forced to issue at least 40 characters before the
contents of the buffer are displayed.
Balance Port LoopBack Test. This key
initiates a loopback test on the port. A special
loopback plug is required in order to perform this
test.
