Expanding Capacity
These are not standard serial ports, damage to serial equipment is
highly likely if connected. 24Vdc signal level exists on certain pins with
a maximum power rating of 5W.
The Precision Hydrogen (Trace) 1200cc has an expandable feature, where the flow ca-
pacity of the unit is increased, by connecting up to 16 units in a Master-Slave format.
Rear Connections
In order to use this feature the units must be connected together via the ‘Master’ port on
the first Precision Hydrogen (Trace) 1200cc, and the ‘Slave’ port at the rear of the next
Precision Hydrogen (Trace) 1200cc unit.
The first Precision Hydrogen (Trace) 1200cc unit is automatically defined as the Master,
and before the connections are made and H2 is supplied, the desired pressure must be
set on all units. This must be the same pressure for all.
The user can now press Start on the Master unit to begin the flow of H2. The Master will
now manage all the other units.
The Data Cables (08-8902) used to connect units together can be purchased from Peak
Scientific.
