Programmable Panel Instrument
SM-1 is the first module in a family of programmable LCD digital panel meters. This microcontroller-based module is
designed round a 6+3 character alphanumeric starburst LCD. The LED backlit display shows the 4 1/2 digit voltmeter
readings as well as a comprehensive operator menu. Navigation through the menu, using the front keypad, is
straightforward and allows the user to select the desired range, decimal point, as well as calibration and alarm level
settings. In a similar way, the user can adjust the visual sampling rate and the level of input filtering. Because all set-ups,
including calibration, are performed in software, there are no user adjustable potentiometers. Besides displaying the
measured input, the module can be made to control external events via its two open collector outputs.

Any displayable character can be shown on the annunciator section of the display. (i.e. mA or oHM or KHZ etc). A lower
case u will display the µ symbol.
Notes:
Do not try to link up more than one module to a RS232 serial bus as it is only designed for two devices (transmitter &
receiver).
RS232 and RS485 communications require 8 Data Bits, 1 Stop Bit and No Parity.
All serial communications must be started with an address nn, the default value of which is “00“. Two or more modules
sharing the same RS485 serial bus cannot have the same address or all will try to reply at once, giving an error condition. If
the address of the module is not known, then use **<command>, where ** is used as an ‘any meter reply’ command. To
avoid device conflict when using this command, only one meter should be attached to an RS485 serial bus at any one time.
All commands must be followed by a CRLF (Carriage Return & Line Feed). The serial port has a certain amount of memory
allocated which will loop around if too many characters are sent, therefore protecting against bad data.
A response of ‘1’ shows that the module has responded.
A response of ‘0’ usually shows that an illegal value has been input by the user, although a meter was attached at that
address.
No response indicates that no meters are connected to that address.
6 Large Starburst Digits
- In Normal Mode, the 6 Large Starburst Digits are used to display the measured input value.
In Menu Mode, the 6 Large Starburst Digits are used to display the menu options.

THE OPERATOR MENU
The user can configure the SM-1 via the 4 push buttons on the front of the module (alternatively, use the SW1 to SW4 pins
on the rear of the module). The LCD offers the user feedback by displaying Menu Levels, Text Messages, Available
Options, Available Scrolling Directions via Up/Down Arrows and a choice of Annunciators. This feedback guides the user
through the configuration process and ensures that the user is aware of the available options.

RS232
The module will remember the current configuration settings for as long as the module receives a correct supply voltage.
When power is removed (or reduced below the “correct” supply voltage) and re-applied, all settings are lost, and the
module powers up to factory default settings. To avoid losing your settings, save them in one of four “File” locations. See
Saving on page SW5 for details on how to save configuration settings.
The RS232 port can be used to communicate with one module at a time. No more than one module must be connected to
an RS232 port at any one time. To connect the SM-1 to a host RS232 port, follow the diagram below.

The two calibration points must be at least 1 count apart, else ERROR will be displayed and calibration will fail.
Input voltages must be different for both calibration points, else ERROR will be displayed and calibration will fail.
The values 00000 and 10000 for SET LEVEL 1 and SET LEVEL 2 correspond with 0V and 1V respectively.
These values are used for factory calibration.
Alarm Levels and Hysteresis: ALARMS
Preset two Alarm trip points with hysteresis. The hysteresis value is the difference in reading between an alarm switching
on and switching off. For example: Hysteresis = 100, High Alarm = 10000, Low Alarm = 200
High Alarm switches on at 10000 and off at 9900,
Low Alarm switches on at 200 and off at 300
Set any unused alarm levels to a value that can in practice never be reached, 999999 (high alarm) or 99999 (low alarm).
When an alarm level is tripped, the appropriate output will go low, the up or down arrow will be displayed on the LCD
