This is a M1 received message to display ascii text on the bottom line of the LCD
display on the keypads in the area specified. Enter the line terminator, “^”, as the
ending character of the line display if less than 16 characters are to be displayed. The
message line, L1 or L2, will need dummy characters to fill the rest of the line for 16
characters each line.
2E - Length as ASCII hex
dm - Display Message On Keypad Command
A - Keypad Area, 1 to 8
C - Clear, 0=clear message, 1=clear message with * key,
2=Display until timeout
B - Beep Keypad, 0=no beep, 1=beep
TTTTT - Display time in decimal seconds, 0=No timeout, 1 - 65535
seconds
L1[16] - 16 ASCII characters for first line
L2[16] - 16 ASCII characters for second line, alternately
scrolled with first line
00 - future use
CC - Checksum
Example: 2Edm11100020abc^efghijklmnopABCDEF^HIJKLMNOP00B2
Would display “abc” on the first line and “ABCDEF” on the second line
