Overall Footprint 89mm x 66mm
Mounting Centres at 43.2mm and 73.5mm (3mm holes provided for pcb standoffs)
Electromagnetic Compatibility (EMC)
Storm 420 Series Encoders are classified as a component with regard to the European Community EMC regulations. It is
the equipment manufacturers responsibility to ensure that systems using the Storm 420 Series Encoder are compliant
with the appropriate EMC standards.
If the electronic system requires input protection against high voltage transients (to meet CE requirements) it is
recommended that an external interface board is located at the point where the external wiring enters the electronic
system enclosure.
Using the 420 Series Encoder with Storm 5000 Series Integrated Keypads
As a combination the Storm Integrated Keypad/ Display Module with Encoder forms a complete serial communications
device. Alphanumeric output from the unit is communicated via the familiar RS232 physical link layer.
The keypad has 20 keys including ten numeric keys and a further ten special function keys. The LCD module displays 80
characters across 4 lines. Both the keypad and LCD module may be backlit from the controller board.
The module has been designed in such a way that it can be used as part of an embedded application, possibly using a
separate host microcontroller or PC to communicate with the module. Alternatively it may be used as an input interface
since the keypad and LCD functions have been designed to be familiar to most users.
The keypad is arranged as a 5-row, 4 column matrix and is scanned and debounced by the module’s built-in
microprocessor. The debounce filter is set at 64ms. No typematic key rollover function is implemented. Multi-key lockout
is, however, implemented in the firmware.
Use of 420 Series Encoder to provide RS232 output from Storm K Range Keypads
When used with any Storm Interface matrix keypad, the encoder can either be fitted directly to the rear of the keypad, or
connected via a ribbon cable. Please note that the cables required to connect a keypad to the encoder are custom cables
and are not provided by Storm.
The encoder can either be fitted directly to the rear of a standard Storm K Range Keypad, or remotely by a ribbon cable.
Where Storm K Range Keypads are underpanel mounted the 420 Encoder can be directly connected, requiring no
additional mounting hardware.
The overall depth required to house the 420 Encoder is 32mm (1.25in) when measured from back of keypad.
Where Storm K Range Keypads are fixed to a panel surface, a ribbon cable and mounting hardware are required (these
items not included with encoder)

Communications Protocol
Physical Link Layer
The module transmits and receives data using RS232 signalling with a voltage swing of approximately ±9V. DIP
Configuration Switch 8 selects between 9600 baud (DIP switch off) and 1200 baud (DIP Switch on). In both conditions, 8-
bit data is used with no parity and one stop bit. This may be summarised as follows….
DIP8 OFF 9600,8,N,1
DIP8 ON 1200,8,N,1
No software or hardware handshaking is used since the data rate is low relative to the bandwidth of the communications
protocol.
Only the TX, RX and Ground signals are employed. The chosen nomenclature is that TX means transmission out of the
module.
Data buffering
Both data transmission and reception are controlled by the module’s built in microprocessor using a pair of stacks- one for
transmitted characters and one for received characters. These allow the application to send data to and from the unit
largely without consideration of the timing constraints of the RS232 physical link layer.
Provided the stacks are not filled, data can be freely sent to and received from the module and the module will buffer the
characters until such times as it is able to process them.
The buffer sizes are as follows…
Data transmission (keypad data out of module) 16 bytes
Data reception (LCD data into module) 48 bytes
Should the buffers be filled, further characters will not be pushed onto the stacks, but instead are discarded.
Character echoing
Characters received from the host terminal/microprocessor may be echoed back to the host by setting DIP Configuration
Switch 2 to ON. With DIP Switch 2 OFF the characters are not echoed.
Characters resulting from key strokes are never echoed to the LCD display, but are simply sent via the RS232 TX pin to
the host application.
Brown-out
If the DC supply voltage drops below 2.85V then the encoder will shut down, and will restart automatically when the
supply voltage is restored back above this level

420 Series Encoder Manual Version v1.9 Oct 2018 Page 4 of 22
LCD Display
The LCD display comprises 80 characters in all, arranged as 20 characters on each of 4-lines. The full range of standard
ASCII characters are available, including lower case letters. Some, but not all, of the extended ASCII characters are
available. Appendix 3 lists the available characters.
Power-up message
At power-on the LCD display shows hardware and software version numbers and communications information for a
period of approximately 5 seconds. After this time the display automatically clears and the cursor is located at the first
character on the left of line 1.
LCD operating principles
The LCD interface is designed to be suitable either for keypad data input (for example as a data entry terminal) or for
embedded microprocessor applications.
It has been designed to operate in a similar way to a teletype terminal since this is a familiar environment to most users
and is consequently intuitive.
The cursor begins on the left of line 1. Entered characters move the cursor progressively further to the right of line 1 until
the end of the line is reached. Entering one further character automatically moves the cursor to the beginning of line 2, i.e.
automatic text wrapping is implemented. This applies to all lines.
Once the end of line 4 is reached, entering one further character results in all lines moving up one place, resulting in the
contents line 1 being discarded, line 2 moves to line 1, line 3 moves to line 2 and line 4 moves to line 3. Line 4 is
subsequently cleared and the cursor moves to the beginning of line 4.
Special characters
The Carriage Return key is supported (ASCII character 0x0D) and results in the cursor moving to the beginning of the
next line, exactly as described above. The Line Feed key (ASCII character 0x0A , or Ctrl-J in HyperTerminal ) is also
supported and gives the same functionality as carriage return.
The backspace key (ASCII character 0x7F) and Del key (ASCII character 0x08) may be used to delete the last entered
character and move the cursor back one place. This can be repeated until the cursor is at the beginning of the current
line, but no further (exactly as a teletype terminal).
The Tab key (ASCII character 0x09) is supported, and enters four spaces, even if this involves a line-wrap.
The Form Feed key (ASCII character 0x0C, Ctrl-L in HyperTerminal) is implemented as a ‘clear screen’ function and
returns the cursor to the beginning of line 1..

420 Series RS232 Encoder Engineering Manual
420 Series Encoder Manual Version v1.9 Oct 2018 Page 5 of 22
Typical implementations
An embedded application where the LCD is written to by a separate microprocessor or computer would typically send a
Form Feed character followed by up to 80 characters, possibly interspersed with carriage returns to reduce the number of
characters to be transmitted.
It is unlikely that such as application would make use of the backspace function since there are unlikely to be errors in
data entry, although the line-wrap feature may be used to allow the microprocessor to treat the display as a contiguous
array of 80 characters with no requirement for carriage returns.
A terminal-like application, however, where the user is permitted to type any characters on the LCD (perhaps using an
application such as HyperTerminal) would almost certainly make use of all the features built into the module such as line-
wrap and special characters to make the interface more user friendly.
LCD adjustment
A potentiometer is provided on the module interface circuit board to allow the contrast of the LCD display to be adjusted.
Wide Temp Range Displays require 0V to -9V ; Std Temp Range Displays require 0V to +5V
