Step-by-Step method for Daisy Chaining
To sucessfully implement Daisychaining the following steps are recommended:-
1.
Decide how many Analysers are to be daisychained.
2.
Make a list of the Serial Numbers of the Analysers and note the order
in which they will be interconnected. For example we have 4 analysers as
follows:
Chain Order
1
2
3
4
3.
Locate the Daisy Chain cables and connect the Daisy_Out of s/n K304 to the
Daisy_In of s/n K461. Connect Daisy_Out of s/n K461 to Daisy_In of s/n K201.
Connect Daisy_Out of s/n K201 to Daisy_In of s/n K006.
4.
Next locate the 2-pin Power cable supplied to s/n K461, s/n K201 and s/n K006
Analysers. It is necessary to apply 5V @ 80mA to each of these Analysers in the chain.
The Green Power Display should be visible on these 3 analysers.
5.
Connect s/n K304 to the PC using the usb cable. The Green Power LED should come on.
If you do not have a USB port available but only a Serial port, connect the s/n K304 to
the PC using the Serial Cable provided AND connect the 2 pin power connector to the
5V 80mA supply.
6.
The supplied Terminal Program can be used to verify the operation of the Daisy Chain.
Connect to the port on which the 1

The response should be OK.
8.
Send getserial and the response should be K304.
