Introduction 2 INTRODUCTION Welcome Thank you for purchasing a Maple Systems MAP450D. You have selected a rugged, reliable and powerful operator interface terminal (OIT) for your application. This manual describes the general operation and features of the MAP450D. About Your Documentation The documentation for the MAP450D consists of: • MAP450D Installation Manual (shipped with each OIT) — Covers the installation requirements of the OIT.
3 MAP450D Operation Manual Operational Overview The MAP450D Operator Interface Terminal (OIT) provides the human-machine interface between an operator and an ASCII compatible computer or host controller. Any controller that is capable of sending and receiving ASCII characters through a serial port can potentially communicate to the MAP450D. The MAP450D receives and sends simple ASCII character strings.
Chapter 1: OIT Configuration 4 CHAPTER 1 OIT Configuration The OIT has many operating parameters that control how it communicates to the host controller. These operating parameters can be changed in three ways: from the OIT’s keyboard when the OIT is in Configuration mode, when the host controller sends a Configuration Control Command, or by downloading a STEPware-100 project. This chapter explains Configuration mode and describes all of the OIT’s operating parameters.
5 MAP450D Operation Manual 3. At Password?, type the setup password and then press the OIT’s ENTER key. If there is no setup password, just press the OIT’s ENTER key. Down/Upload mode? Y displays. 4. At Down/Upload mode?, press the OIT’s Period (.) key to alternate between Y and N, then press the OIT’s ENTER key to accept and continue. Option Y Description Allows you to enter Download/Upload mode for communication with STEPware-100. N Displays the OIT’s current operating parameters.
Chapter 1: OIT Configuration 6 Operating Parameters The OIT has many operating parameters which determine how it communicates to the host controller. These operating parameters can be changed in three ways: from the OIT’s keyboard when the OIT is in Configuration mode, when the host controller sends a Configuration Control Command, or by downloading a STEPware-100 project. Each operating parameter is described in detail below.
7 MAP450D Operation Manual Parity Setting This parameter determines the parity that the OIT uses to communicate to the host controller. Options are Even, Odd, None, Mark, Space. When the OIT is in Configuration mode, no parity is used to communicate to STEPware-100 regardless of how this setting has been configured. Factory Default: No Parity To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2.
Chapter 1: OIT Configuration 8 Stop Bits Setting This parameter determines the number of stop bits that the OIT uses to communicate to the host controller. Options are 1 Bit or 2 Bits. When the OIT is in Configuration mode, one stop bit is used to communicate to STEPware-100 regardless of how this setting has been configured. Factory Default: 1 Bit To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2.
9 MAP450D Operation Manual Software Handshaking Software handshaking, which uses the XON/XOff format, is available only in Interactive mode. The following rules apply: 1. When the host controller sends an XOFF control code (hexadecimal 13), the OIT halts transmission of any data to the host controller until the host controller sends an XON control code (hexadecimal 11). While transmission is halted, each OIT keypress continues to be displayed on the OIT but no data is transmitted to the host controller.
Chapter 1: OIT Configuration 10 Operating Mode Setting This parameter determines whether the OIT operates in Interactive, Block, or Network mode. Refer to Chapter 2: Operating Modes for more information. Factory Default: Interactive To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2. In the OIT Operational Settings group box, select the desired operating mode from the Operating Mode option buttons. To modify this parameter in Configuration mode: 1.
11 MAP450D Operation Manual Append Linefeed Setting This parameter determines whether a linefeed LF control character (0x0A) will be appended to any carriage return CR control character (0x0D) that is sent to the OIT from the host controller. If enabled, this will cause the cursor of the OIT display to move down to the next line of the display when a CR is received from the host.
Chapter 1: OIT Configuration 12 Block Echo Setting This parameter determines whether block echo is used when the OIT is operating in Block or Network mode. If enabled, each character sent to the host controller from an OIT keypress is also sent to the OIT’s display. If disabled, asterisks are sent to the OIT’s display in place of the characters. Factory Default: Enabled To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2.
13 MAP450D Operation Manual Delayed Linefeed Setting This parameter determines whether the OIT executes an LF control code (hexadecimal 0A) immediately or when the next character is received. If enabled, the OIT does not execute an LF control code received from the host controller until the next character is received. If disabled, the OIT immediately executes the LF control code. This parameter is used most often with host controllers that automatically append an LF control code to each data transmission.
Chapter 1: OIT Configuration 14 Network Address Setting This parameter determines the network address used by the host controller to communicate with this OIT when in Network mode. Options are 1 to 255. Factory Default: Not Applicable To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2. In the OIT Operational Settings group box, enter the desired network address in the Network Addr. text box. To modify this parameter in Configuration mode: 1.
15 MAP450D Operation Manual Cursor Type Setting This parameter determines the type of cursor used in the OIT’s display. Options are No Cursor and Underline. Factory Default: Underline To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2. In the OIT Operational Settings group box, select the desired cursor type in the Cursor Type list box. To modify this parameter in Configuration mode: 1. At Cursor:, use the OIT’s Period (.) key to select the desired cursor type.
Chapter 1: OIT Configuration 16 Local Keyboard Setting This parameter determines whether the OIT’s keyboard is enabled. Factory Default: Enabled To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2. In the OIT Operational Settings group box, select the Local Keyboard Enabled check box. To modify this parameter in Configuration mode: 1. At Keyboard:, use the OIT’s Period (.) key to enable or disable the local keyboard.
17 MAP450D Operation Manual Local Setup Setting This parameter determines whether the OIT allows you to access Configuration mode. If this parameter is disabled, you will not be able to enter Configuration mode. Since you must enter Configuration mode to reprogram the OIT, you will not be able to reprogram the OIT until the host controller sends a Keyboard control command enabling local setup again. Factory Default: Enabled To modify this parameter using STEPware-100: 1. Open the Configuration Editor. 2.
Chapter 2: Operating Modes 18 CHAPTER 2 Operating Modes Your OIT can be programmed to operate in one of three operating modes: Interactive, Block, or Network. These modes affect how the OIT sends data to and receives data from the host controller. This chapter explains the differences between the three operating modes. Refer to Chapter 1: OIT Configuration for information on how to change the operating mode. Interactive Mode In Interactive mode, the OIT immediately sends data to the host controller.
19 MAP450D Operation Manual OIT Key Data Sent to Host Delete DEL Enter Line Terminator (ETX, CR, LF, or CR/LF) Local Echo Mode Operation Deletes the character to the left of the cursor and moves the cursor one position left. If the cursor is on the first position of a line, this key has no affect. If the cursor is on the last position of a line and a character is displayed there, the character is deleted and the cursor remains on the last position of the line.
Chapter 2: Operating Modes OIT Key Shift + (8 $) Shift + (9 +) Space .Shift + (. -) Clear Delete Enter 20 Operation Sends dollar sign ($) to the Keyboard Input Buffer and the OIT’s display. Sends plus sign (+) to the Keyboard Input Buffer and the OIT’s display. Sends space to the Keyboard Input Buffer and the OIT’s display. Sends period (.) to the Keyboard Input Buffer and the OIT’s display. Sends hyphen or minus sign (-) to the Keyboard Input Buffer and the OIT’s display.
21 MAP450D Operation Manual When using Network mode, always follow these rules: 1. Every OIT on the network must be assigned a unique network address. 2. Every OIT on the network must be programmed to use the same line terminator. 3. Always have the host controller send a line terminator immediately before sending an OIT network address.
Chapter 2: Operating Modes 22 Sample Network Session Below is a sample session showing a host controller communicating with three OITs on a multidrop network. The OITs have network addresses of 1, 30, and 100. The line terminator is set to ETX. NOTE: Spaces are shown for clarity only and should not be used.

Chapter 3: Using the OIT's Display 24 CHAPTER 3 Using the OIT’s Display The OIT displays data input from the OIT’s keypad, data sent from the host controller, and data stored in predefined messages. When a printable ASCII character is sent to the OIT’s display, it is displayed at the OIT cursor’s current location (unless the host controller is writing to a display variable). The cursor is then advanced one column to the right on the current display line.
25 MAP450D Operation Manual When the cursor reaches the end of the current display line: • in Interactive mode, additional characters overwrite the character in the last column, unless the word-wrap feature is enabled. If word-wrap is enabled, the cursor moves to the next line of the display. • in Block or Network mode, the OIT sounds an error beep and stops accepting keypad input.
Chapter 3: Using the OIT's Display 26 In addition to the standard printable ASCII characters, the host controller can also display characters from the OIT’s extended character set. Refer to Appendix C: Extended Character Set for a list of the extended characters available on the MAP450D and the ASCII codes the host controller should send to display them. The host controller can control the location of data on the OIT’s display by sending control commands and control codes.
27 MAP450D Operation Manual Displaying Text from Predefined Messages In some applications, the OIT may be required to display many messages to the OIT operator concerning the state of the control system. If these messages are always the same, they can be stored in the OIT and displayed whenever the host controller requests them. The OIT has the ability to store up to 500 predefined messages.
Appendix A: Control Commands 28 APPENDIX A Control Commands Control commands are multiple ASCII characters, starting with the command initiator (ESC control character) and ending with the command terminator (STX control character) or line terminator. These commands allow the host controller to request and send information to the OIT. Control commands are always sent by the host controller to the OIT. The first letter after the command initiator is the command letter.
