jfk Posted August 5, 2019 Report Share Posted August 5, 2019 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. Quote Link to comment Share on other sites More sharing options...
