Control Connections
After positioning all of the modules in the system, it is
necessary to connect each module to the system
controller. Two types of electrical connection must
be made.
The manometric module must be connected to the
305 Master pump.
All of the slave pumps must be connected to
the Master pump using the GSIOC cable provided.
Connecting the Manometric Module
The manometric module has two functions, to
dampen the pulsations of the pump and to supply
the current pressure value to the Master pump. The
Master pump needs this information to accurately
control the flow rate and to ensure that the system
pressure is not above or below the control limits
entered in the program. The opposite figure shows
the connection for the manometric module.
Connecting the 305 to other Gilson
Modules
The 305 Master pump and the other modules in the
system communicate using the Gilson Serial Input/
Output Channel (GSIOC). Each slave module
controlled by the 305 Master has a GSIOC connector
on its rear panel and is connected to the 305 Master
using the GSIOC cable provided. It is possible to
connect the 305 Master pump to two slave modules
using this cable. If there are more than two slave
modules, two GSIOC cables can be connected together.
The opposite figure shows the GSIOC connections for
a system with 3 elution pumps and on injection pump.
To connect the 305 Master pump to the slave pumps:
Connect the socket marked GSIOC TO SLAVE on
the rear panel of the 305 Master pump to the slave
pumps using the GSIOC cables provided.
Each slave pump and the injection pump must have
the GSIOC ID number set as appropriate, see the
opposite table. Ensure that their respective ID numbers
have been correctly set. This can be checked by
Slave pump I.D. Number
