Yes. Before you can send any commend (except ping) you must first establish an authentication level. For cluster commands, it is best to set level 1. i.e. 

authenticate 1

terminated with a carriage returned (hex 0D).

Otherwise, you are not authorized.

I do not know how your control product sends its strings. All commands to WATCHOUT must have a carriage return at the end of the command. When typing a command from telnet, this is accomplished by hitting the return key. Control products use various methods of sending the carriage return at the end of the command string. Some use /r. Some send the the two digits representing the single byte hex value with some hexadecimal value indicator, , I have seen 0Dh, etc - for example, WATCHOUT itself uses a dollar sign ($) to indicate the next two digits are a single byte hex value, so in a WATCHOUT output cue, you would type $0D to send a carriage return. The method used to define hexadecimal bytes is determined by your control product.
