When specified, the EEG (or ECG) electrode inputs will
normally be routed through the CED1902-11 Electrode Box
(see page 2), which accepts standard 1.5mm (optionally 2mm)
safety plugs, and connects to the 1902s via a 6-pin DIN plugs.
Alternatively, users may wire the 6-pin DIN plug supplied with
the 1902 to their own requirements.
A full kit of mating front-panel connectors is supplied with the
1902, as are the serial-line control cable and the power supply
mains cable.
The standard connector kit comprises:
• One 8-pin DIN plug for transducers
• One 4-pin mini DIN plug for the trigger
• One 6-pin DIN plug for electrode signals
Further connectors can be obtained from a variety of suppliers
but, for reference, we have obtained ours here:
Component Part number Supplier UK tel. No.
Trigger, 4-pin mini DIN 152-208 Farnell 08701 200200
Transducer, 8-pin DIN 809-792 " "
Electrode, 6-pin DIN 809-779 " "
• To meet the requirements of EN60601-1 only the DIN parts
specified (apart from trivial details of colour, etc.) can be
used for the electrode connectors.
• If the DIN 6-pin connector is used, the plastic cover must be
kept fully pushed onto the plug body at all times.
