Section 1. Overview
The Storm Interface 1200 Series Sub-Miniature Keyboard has been developed for use in a new
generation of web enabled public telephones and transaction terminals. This small but highly responsive
keyboard is suitable for use in exposed or hostile environments and its robust construction is highly
resistant to hard use, abuse and vandalism. It is sealed against water and dust to ensure responsive and
reliable data entry in the most demanding situations. The keyboard’s front panel and keytop characters
can be customised to complement the colour scheme, design and function of almost any host equipment.
Encoding electronics are an option that can be specified and integrated into the keyboard construction
providing a plug compatible, ready to use, solution for almost any PC based application.
Weather and vandal resistant for outdoor and unsupervised public environments
Integrated PC/USB compatible interface (optional)
Rapid, responsive and reliable data entry
Stainless steel front plate
Easily and securely installed in public web-phones, vending machines, automated
teller machines, transaction terminals, public internet kiosks etc.

Section 3. Installation into Host Equipment
The 1200 Series Sub-Miniature Keyboard must be securely fitted into a facia panel or equipment casing.
For effective resistance to vandalism, abuse and rough use the keyboard should be installed from the
underside of a panel, with the operational face of the keyboard accessible through a rectangular aperture
in the panel, see Appendix 2.
The keyboard is securely held in place by a retaining plate (supplied as part of the mounting kit, part number
1200-MK000x) which is positioned over 8 M3 x 16 mm studs, see Appendix 2.
Recommended dimensions and profile for the panel aperture and positions of the fixing studs are detailed
as “non-revision supported copy”. The keyboard’s integral sealing rib (positioned on the top face of the
peripheral flange) is compressed between the flange’s top face and the rear surface of the fascia panel.
The rear surface of the fascia panel must be rigid, flat and free of debris to achieve rated resistance to
water and dust. The keyboard’s integral seal should be checked to ensure it is free from damage and debris
prior to installation or refit.
The overall dimensions are as shown below:
1200 Series Sub-Miniature Keyboard
Overall Length mm (ins) 175,0 (6.8 in)
Overall Width mm (ins) 85,0 (3.3 in)
Overall Depth underpanel mm (ins) 21,5 (0.85 in)
Weight (kg) 0.549

Section 4. Connectors and Connections
The 1200 Series Sub-Miniature Keyboard is supplied either as a matrix keyboard with row column output via a 20
way Molex Connector, or with an integral encoder available with either PS2 only or PS2/USB switchable output
(which is configured by the user via a switch on the encoder pcb at the time that the cable is connected to the
keyboard).
PS2 and USB cables are not supplied with the keyboard, but are available to purchase separately, see Section 7
Matrix Version with Row/Column Output
The keyboard’s 53 keys are momentary contact (carbon to gold on nickel on copper contact) switches, positioned
on a 6 row x 14 column circuit matrix as defined in Table 1. This circuit matrix is terminated via a 20 way Molex
Picoflex connector (part number 90814-0820). See Figure 1.
To connect a 20 line ribbon cable to this connector, it is recommended that the mating Molex Picoflex connector
(Series 90327, 20 way connector) be used. Current specifications and ratings for these components (or other
compatible molex connectors) should be sought from the manufacturer at www.molex.com
