the weight is in motion and/or not stable.
3) Print on CTS (Clear to Send, a RS-232 handshake line) – By toggling the CTS line from space to mark, the
print string will be transmitted. If an interval is set, the string will continue to print as long as CTS is asserted.
“Motion Check” determines if printing is allowed (Motion Check Off) or disallowed (Motion Check On)
when the weight is not stable.
4) Print On Weight Change – Every time the weight changes 1 full display count or more, one transmission of
data will occur. “Motion Check” determines if printing is allowed or disallowed when the weight is in motion
and/or not stable. Interval has no effect in this mode.
5) Print on Stable Load – When the load weight exceeds the Total Threshold and motion ceases, one transmis-
sion of data will occur. Once transmitted, the scale must return below the Total Threshold to re-enable the
transmission. Interval has no effect in this mode.
6) Print On Total – When the weight is totaled, one transmission of data will occur. Once transmitted, the scale
must return below the Total Threshold (See Total Setup) to re-enable the transmission. Interval has no effect
in this mode.
Using Print on Total with the Auto Total enabled should not be used with any weight print-out other than W5, W6, W7, or W9 (because the actual total
doesn’t occur until weight drops below the threshold, so the weight used for the Total would no longer be on the scale). Use “Print on Load” to print the
weight used for the total.
7,8,9,10) Print on Set-Point – Set point 1, Set point 2, Set Point 1 and 2, or Set-point 1 or 2 can be confi gured to
trigger a data print. Once transmitted, the set-point must go off then on again to transmit again. Print on a set
point can also be confi gured to print when two set-points are true (AND) or when either Set Point 1 or Set
Point 2 are true (OR). This confi guration allows printing when the weight is outside two limits or when the
weight is inside two limits (windowed). “Motion Check” determines if printing is allowed (Motion Check
Off) or disallowed (Motion Check On) when the weight is not stable.
In addition to the Control modes above, the master CellScale can also force formatted print strings out the Comm
Port. See the CellScale manual for more information on Set Point messages and other types of remotely gener-
ated messaging.
There is also a special print mode used with the VIEW key. Pressing
VIEW∑ (F-Key programmed for View
Total) followed immediately by the PRINT key will output just the current ID Codes total and Total Count. See
“@W7” for formatting information on this special output.
COMM PORT SETUP MENU
[1] ENTER EDIT STRINGS: is the heart of the communications system. It controls the data output generated
by the 9750A Meter.
1) Data Out String: This is the main formatted output string. Any weight or other data can be included with the
use of the MSI “@” codes. Up to 512 Bytes
2) End String: The End string can be 0 to 64 characters long. Most commonly used for Carriage Return (CR)
or Line Feed (LF), or CR/LF. The EOL string defaults to Carriage Return / Line Feed. See “Programming
the End of Line String for an example.
3) Start String: The Start string can be 0 to 64 characters long. It is intended for commonly used commands that
usually precede printed lines. Typically ESC codes are used on some printers to enable or format the print
string. The start of line string is usually referred to as the “SOL string”. The string defaults to empty.
4) Wait Character: The “WAIT CHARACTER”, if entered, will cause the print output to pause after each EOL
string until the designated character is received by the port. To use the Wait Character mode, the Comm Port
mode must be Duplex. Once the proper Wait Character has been received the 9750A will output the next data
string up to the next EOL string.
5) Aux String: The Aux String is an additional formatted output string primarily intended for use in the Data
Logging feature to provide additional information embedded in the data stream.
6) Ack String: The Acknowledge String is sent back to the Host port that sent a message to this 9750A. See
“Text Messaging” for more detail. This string defaults to the ASCII ACK command but any message up to
32 bytes can be entered.
[2] OUTPUT INTERVAL: Selecting “Print Once” CLR means that after the trigger condition, a single trans-
mission of data will occur. For continuous output, a print interval can be entered from 50ms to 50 days in 50ms
increments. Used in conjunction with the Continuous Trigger mode, this can generate a time based data-logging
system. An interval of 50 milliseconds means that the scale will output data at the highest rate possible (also
limited by the transmission rate from the CellScale). Interval used with other control modes can be useful for
control and monitoring purposes.
