@@ -12,7 +12,7 @@ This binding requires an adapter to interface to the Pentair system bus.
 This bus/wire runs between the Pentair control system, indoor control panels, IntelliFlo pumps, etc.
 It is a standard RS-485 bus running at 9600,8N1 so any RS-485 adapter should work and you should be able to buy one for under $30.
 Pentair does not publish any information on the protocol so this binding was developed using the great reverse-engineering efforts of others made available on the internet.

 Once you have the interface connected to your system, it is best to test basic connectivity.
 Note the protocol is a binary protocol (not ASCII text based) and in order to view the communication packets, one must use a program capable of a binary/HEX mode.

 There are no overall binding configurations that need to be set up as all configuration is done at the "Thing" level.
