To send a command to activate the relay for one minute, and then have it deactivate automatically, send the
following command. Note: The RCD-1 unit must have its timer already programmed to be one minute,
using the Output 1 Period field in the programming software. The RCD-1 can be programmed to have a
delay value as long as approximately one hour and 45 minutes, or as short as one second. See the
Programming Section of this manual for details.

Checksum Example:
Message: 7014123450
Function code = 70
Command code = 14
Password = 12345
Data = 0 (turn output relay OFF)
Checksum: 37h XOR 30h XOR 31h XOR 34h XOR 31h XOR 32h XOR 33h XOR 34h XOR 35h XOR 30h
= 03h
Converting the answer, 03h, to HEX ASCII yields two characters, one for the 0 and one for the 3.
Therefore, the actual message to send to the RCD-1 is :
701412345003
Note: ASCII-HEX representation of Checksums can result in non-numeric characters so alphanumeric
POCSAG formatting should be used when command checksums are present. Also, command
passwords/sub-addresses can also contain non-numeric characters.
