The SMD-12 does not require a computer or any other device to store messages or display these messages. Messages can be entered and stored by using switches mounted on the unit. For those wishing to use the SMD-12 with a computer however, an RS-232 serial port connection is provided, along with commands to store and display messages.
Self-contained printed circuit board assembly with no wiring or connections necessary except those required to connect power and user contacts.
Includes a rugged steel enclosure that utilizes a stud mounted front panel.
Contains four Liteon LTM8647 or equivalent 2-digit 14 segmant alphanumeric LED displays with 0.56 inch height characters, providing a total of 8 alphanumeric characters plus common punctuation. Messages can be up to 32 characters and will scroll when over 8 characters.
12 messages can be stored and recalled for display, and a 13th message can be used as a "home" message to be displayed when other messages are not.
Operate on 12 to 30 volts regulated or unregulated DC, connected through screw terminals.
RS-232 pinout matches the 9-pin serial port of IBM PC compatible computers for easy connection to these computers.

On-Board Switch Programming Mode:
Jumper SWP should usually be in the "NORM", or default position, which is to the top when viewed from the front of the unit. It should be changed to the "PROG" position which is to the bottom, for editing and storing messages using the on-board switches.
Serial Port Programming Mode:
Jumper SPP should usually be in the "NORM", or default position, which is to the top when viewed from the back of the unit. It should be changed to the "PROG" position which is to the bottom, for editing and storing messages using the serial port.
Baud Rate:
Jumpers B0 and B1 select the serial port baud rate depending on which position you place the jumpers, to the left or to the right.

If more than one message connection is grounded, the message with the lowest number is displayed. This priority allows message number 13 to be used as a "home" message, which will be displayed if no other message is being displayed. To use this feature connect the Message 13 connection on the terminal block is connected to ground.
The Count Up and Count Down connections will function even if the SMD-12 is not in the counter mode. This will allow counting to occur during the display of messages and still be accurate when the count is again displayed.
The SMD-12 must be in the Counter Mode in order to use the Clear Count function.
Except for the Count Up and Count Down connections, any change in the terminal block connections will halt any message that has been sent to the display through the serial port, and a new message will need to be sent.
The following is a pinout of the serial port signals:
SMD signal Pin PC signal
1 DCD in
transmit 2 receive
receive 3 transmit
4 DTR out
ground 5 ground
6 DSR in
7 RTS out
8 CTS in
9 RI in
Pins 1, 4, and 6 are tied together on the SMD-12, and pins 7 and 8 are tied together.
1. To store messages in the unit.
2. To view the messages stored in the unit.
3. To display messages sent to the unit through the serial port.
4. To monitor the messages and counts being displayed.
In order to place the display into the mode used to enter messages, the display must be connected to power and the jumper labeled SWP changed from the NORM position to the PROG position. (This jumper may be changed at any time while the power is applied without disturbing the unit.) This is accomplished by pulling the small rectangular jumper plug from its normal position on the top 2 pins and installing it on the bottom 2 pins. After all message editing and storing is complete, the jumper must be placed back in the NORM position in order to use the display in the normal manner.
Once the jumper SWP has been placed in the PROG position, the unit will display EDIT 01, indicating that it is ready to begin editing message #1. To change to the message that you intend to edit, use the UP and DOWN buttons. When the message you intend to edit is displayed, press the ENTER button. (Pressing the CANCEL button at this point will have no effect. To exit the message editing mode you must change SWP back to the NORM position.)
After the ENTER button is pressed, the first 8 characters of the message you selected to edit will appear and the first character of the message will be flashing. (If this particular message has not been entered or edited, the message will be BLANK.)
Whenever a character in the message is flashing it can be changed to other characters using the UP and DOWN buttons. To move to a different character in the message use the LEFT and RIGHT buttons. The message you are editing will scroll to the left and right as you move from character to character with the LEFT and RIGHT buttons. Messages can be up to 32 characters, and characters in the message will be spaces unless changed to other characters. This is why you can scroll to the right where there appears to be no characters.
After you have edited a message to your satisfaction, press the ENTER button to store the message. The display will display the word STORED if the message was successfully saved, and then again display the message EDIT XX (where XX is the message you just edited) to indicate that you may select another message to edit. If at any time while editing a selected message you decide to abandon the editing, simply press the CANCEL button and the display will go back to where you can select another message.
After editing all of the messages you need, change jumper SWP back to the NORM position.
(If at any time during the message editing process you change jumper SWP back to the NORM position, the display will exit the message editing mode and no changes will be made to the message you were editing. Unless the unit displays the STORED message, the message you are editing has not been saved.)
When jumper SPP is in the NORM position and the unit is in the normal operation mode, any valid group of characters followed by a carriage return will be displayed just as though the characters were a message stored in the unit.
When jumper SPP is in the PROG position and the unit is in the programming mode, the SMD-12 uses a carriage return/line feed sequence followed by a ">", or "greater than" character as a prompt. Commands not understood by the SMD-12 or commands sent with improper parameters are responded to with the word "ERROR" and a carriage return/line feed sequence.
Notes:
1. Except for the Count Up and Count Down connections, any change in the terminal block connections will halt any message that has been sent to the display through the serial port, and a new message will need to be sent if displaying messages via the serial port.
2. Conversely, any command sent via the serial port to display a message will halt any message caused by contact closure, and the contact closure will need to be opened and then closed again to display the stored message with that particular contact closure.
In effect, what this means is that commands from either the contact closures or serial port will override each other.
To use this command, jumper SPP, the serial port programming jumper, must be in the NORM position.
Sent to SMD: [message]<CR>
where [message] is a message of up to 32 displayable characters.
Received from SMD if accepted: all valid characters are echoed
Received from SMD if rejected: invalid characters are ignored
View messages
To use this command, jumper SPP, the serial port programming jumper, must be in the PROG position.
Sent to SMD: <ESC>V<CR>
Received from SMD:
MESSAGE ONE <CR><LF> MESSAGE TWO <CR><LF> MESSAGE THREE <CR><LF> MESSAGE FOUR <CR><LF> MESSAGE FIVE <CR><LF> MESSAGE SIX <CR><LF> MESSAGE SEVEN <CR><LF> MESSAGE EIGHT <CR><LF> MESSAGE NINE <CR><LF> MESSAGE TEN <CR><LF> MESSAGE ELEVEN <CR><LF> MESSAGE TWELVE <CR><LF> MESSAGE THIRTEEN <CR><LF>(and back to the prompt)
Note that messages are stored in the SMD-12 padded with spaces up to 32 characters, and when they are sent in response to a view command, the spaces are included, even though they may not be seen when viewed on a terminal.
Messages numbers that have not yet had messages stored in them will send the word "BLANK".
Store a message
To use this command, jumper SPP, the serial port programming jumper, must be in the PROG position.
