Command dNNNNss
Reply A
NNNN- 4 digits message (0000-9999) in string type, ss- message display
duration in seconds (01-99), also string type.
This command is used to display 4 digits message on TR510E's LED
display for a duration time. The message code and its meaning are defined by
user, only numeric can be defined, do not define alphabet. The code range is
from 0000 to 9999 in string type.
If TR510E is not in extended mode, this command will be denied.
Host sends "relay activation" duration ('l', 6CH)
Command lNN
Reply A
NN- relay activation duration in 01-99 (string type) seconds, 00 should never
be used as duration.
This command 'l' (lower case 'L') is used to assign relay activation duration
in seconds. When relay is used to control Bell, send this command to TR510E
will get error code- "command failed".
If TR510E is not in extended mode, this command will be denied.
