Figure 2: TriLog external connections
1. Sensor input (In) sockets marked In-1/8 In-2/7 In-3/6 and In-4/5: These sockets
are used to connect the sensors. Normally, all four sockets can be used
simultaneously.
To connect a sensor to the TriLog use one of the sensor cables. Plug the
stereo plug into the data logger, and the mini-din plug into the sensor -
arrow facing down.
In order to connect more than 4 sensors at a time, use the splitter cables, which will
enable the connection of up to 8 sensors simultaneously. When a splitter cable is
connected, it must be connected to the socket in the correct numerical order (e.g. for
5 sensors, connect the splitter cable to In-4/5). One of the two splitter cables is
marked with
P1
- that is the main input (the lower input number), the second line is
marked with
P2
- indicating that it is the secondary input (the higher input number).
Connect up to four input splitters (DT225) to split the TriLog
’
s inputs starting with In-4
(the splitters
must
be connected in order):
In-4 splits into In-4 and In-5
In-3 splits into In-3 and In-6
In-2 splits into In-2 and In-7
In-1 splits into In-1 and In-8
