A 16/16 parlour with PULSE-8 2/2 configuration is illustrated below.
Every stall has two solenoid valves fitted, one for each pair of teat cups on
the cluster.
The teat cup pairs may be arranged either diagonally or front-to-
back and because they are connected to different PULSE-8 channels, will
pulse alternately.
The numbers in circles represent the PULSE-8 channels.

The illustration right shows a 16/16 parlour with the PULSE-8 in 4/1
configuration.
The parlour is divided into 4 quadrants each of four stalls with one
PULSE-8 channel driving each quadrant. There is only one solenoid valve
to each stall, so all four teat cups on a cluster are pulsed together.
