SECTION 11 – TEXT MESSAGING
The MSI-9750A provides a means for sending messages from host computers directly to the 9750A display. The
remote computer uses a host command to send data to any 9750A on the same network (0-31). Once the 9750A
receives a text message, it is displayed until a key is pressed. By including the standard ASCII bell character ® ®
(control G), the message can also send an alert tone that persists until the message is acknowledged.
HOST MESSAGE DESIGN
The 9750A display is limited to 160 characters maximum. Characters beyond 160 characters will not be displayed.
The size of the message characters is automatic and based on the length of the message. Messages shorter than
16 characters will be displayed in the large font in one or 2 rows (2 rows by 8 characters). Messages from 17 to
56 characters will be displayed in the medium font in 2 to 4 rows (4 rows by 14 characters). Messages longer
than 56 characters will be displayed in the small font (8 rows by 20 characters). Words that cross line boundries
will be split.
In order for a host to send a message to an individual 9750A, the host must know the address of the 9750A. The
string required for the host to transmit through a CellScale modem is:
MSGxxx*This is the transmitted text;
Where xxx is replaced by the address of the 9750A. It is not necessary to use three digits if the address is
smaller.
Example1
(^ is used to designate a space)
Target 9750A address is 52, message is intended to be in large font on the 9750A screen.
MSG52*^^POUR^^5000 lb.;
The spaces are included to center the wore “POUR” and to space the weight to the next line (8 total characters
per line). This will result in a 9750A screen that appears like this:
POUR
5000 lb.
The message will fl ash to attract attention. This message will remain until any key is pressed on the 9750A.
Example2
Target 9750A address is 150, message is intended to be in medium font on the 9750A screen.
MSG150*Load 550kg.^^^Send to Loc^^^B1234567890^^^Warehouse 2;
The spaces are included to pad the fi rst two lines (14 total characters per line) to prevent words breaking on the
screen. This will result in a 9750A screen that appears like this:
L o a d 5 5 0 k g .
