Connecting everything up

Top Previous Next

Connect each of the input/output panels to the EX233 distribution board with the 34-way cables

The three columns on the EX233 board are labelled X, Y and Z; you may find it useful to label the cables going to the input/output panels accordingly. It helps when wiring things up later.

Connect your apparatus

Plan your wiring diagram before starting (see Amplicon wiring diagram). To remind you:

•	Connect Med Associates inputs to A0-7, B0-7 and C0-7 on the SK8 0V block of the EX230 input panel.

•	Connect each output control wires to either the N/O or the N/C pin of one of the relays on the EX213 output panel.

•	Ensure that output ground wires are (eventually) connected to the COM pin of the same relay.

Plug the computer into the uninterruptible power supply (UPS)

Make sure the system looks OK

It should look something like the schematic shown earlier.

Ensure you do not place subjects in the operant chambers until...

... you have installed the system, tested the hardware and read the discussion of life-threatening devices and safety systems.
