 Notes:  

* These properties are read-only.

² Chromeleon supports these properties only if the injection port setting on the Sampler tab page in the Server Configuration is Injection ports = Position 1 and 2.

³ Chromeleon supports these properties only for the CP-8400 in the User_Defined injection mode. An error message is displayed if these properties are set in an injection mode other than User_Defined:
