Red Lion LDSS - Manual (Page 8)

Data Receive Delay Timing
Upon receiving a string terminator character , the Serial Slave requires
a delay time to process the received data and prepare for the next string. During
this delay, the meter disables serial data reception.
The Data Receive Delay Time is programmable in Module 1, with a
minimum delay of 10 mSec. By extending this delay, the Serial Slave can ignore
data sent by the host which is not intended for display. This data includes
additional characters such as a or redundant , which might follow a
serial data string. This could also include additional data strings sent as part of
a data block, where only the first string is intended for the Serial Slave display.
In this case, the delay time should be programmed to exceed the total
transmission time for the entire data block. This results in the Serial Slave
displaying the first string of the data block and disabling data reception during
transmission of the additional strings.
The Receive Delay Time must be set to expire at a point where no data is
being sent to the Serial Slave. This prevents the unit from enabling data
reception in the middle of a character or data string, which could result in an
incorrect display when the string is processed.
