3.4.4 Loop Back
When enabled, this feature provides a loop-back self test for use in diagnosing serial communications errors. The
loop-back self test checks the function of the remote display serial port by sending and receiving data to itself.
The following table shows the required
connections.
If Port 1 receives nothing from Port 0 for
three seconds, the following message is displayed on the remote
display:
Fail 1
If Port 0 receives nothing from Port 1 for three seconds, the following message is displayed on the remote
display:
Fail 2
If communications are successful between the two, the following message is displayed:
Pass

3.6 Demand Print Displaying
The indicator and the LaserLight remote display can be set up to do a demand print display for such applications
as cattle weighing. This is useful if you want to show and keep the last weight of an animal.
Demand print display can be set up using Auto-L
earn when the Port 0, Hold Weight parameter is turned On, and it
is set up manually by formatting the baud rate, data bits, parity, etc. of the remote display and the indicator.
Using Auto-Learn, ensure
HOLD WT is on and continuously push the print button on the indicator to attempt a
demand print display.
3.7 Serial Commands
The LaserLight remote display has the ability to receive commands, display messages, or use a digital I/O (2
inputs & 2 outputs). When interfaced to an indicator having a configurable serial string like the IQ plus 355, 710,
800, or 810, the print ticket format can be configured to allow the user to use the
Print key to send a message that
temporarily interrupts the streamed weight display. The amount of time the message is displayed is defined by
the
MSG TM (message time) parameter under the CONFIG menu in the remote display, for the 7-segment remote
display.
If the
LaserLight remote display is interfaced with a programmable smart indicator like the 920i, a user program
can be written to allow the user to send messages utilizing softkeys or events. When sending messages from a
user program, the user can send one message to temporarily override the streamed weight display or send
multiple messages to be displayed one at a time for several seconds each, replacing the weight display all
together if desired.
