About This Guide Introduction This manual is intended for programmers who are creating programs that will run on the FMT1000 Series of data collection computers. All of the FMT1000 Series computers have the same internal architecture and are covered in this manual. Differences such as keyboard layout are noted where necessary. The most important thing to remember about programming the FMT1000 Series computers is that they are truly DOS PC compatibles and that most software will run without modification.
FMT1000 Series Programmer’s Guide Key Conventions for the FMT1000 Series Programmer's Guide Keys and key sequences are printed in and enclosed in broken brackets. For example: • the enter or return key. • the tab key. • - the FMT1000 Series computer key sequence equivalent of the standard IBM PC key combination. • the F6 function key. • User Defined Key. See page 2-101 for more information about user-defined keys.
Chapter 1 FMT1000 Architecture Introduction The FMT1000 Series includes three models: • the compact FMT1020 • the rugged FMT1040 • the FMT1060 for time clock applications. The specific features of each model are covered in the installation guide provided with each unit. The architecture and command set are common to all models. Throughout this manual all models will be referred to as the FMT1000 Series computer.
FMT1000 Series Programmer’s Guide information coming from I/O devices, either by using the keyboard port, making the data appear as though it had been typed, or by sending it to COM2. Complete details of coprocessor operation and interfacing are contained in Chapter 2 of this manual. Figure 1-1.
FMT1000 Architecture Please continue to refer to Figure 1-1 as the other architectural features of the FMT1000 Series computer are described below. CPU The FMT1000 Series CPU is the Chips & Technology F8680 PC/Chip processor. This highly integrated processor contains much of the basic I/O for the FMT1000 Series computer in addition to the CPU core. This processor, as used in FMT1000 Series computer, executes the 8086 instruction set, with an execution speed comparable to a 12-MHz 80286 processor.
FMT1000 Series Programmer’s Guide Memory The FMT1000 Series computer contains 1 MB of RAM. This memory may be exploited in various ways to afford optimal usage in a variety of systems. The first usage choice is presented during system setup, where a selection is made from two possible memory maps, A and B, as shown in Figure 1-2. Figure 1-2.
FMT1000 Architecture • Configuration A allows a base memory partition of 640 KB, which is the norm for PC-compatible computers. • Configuration B extends the base memory partition by 96 KB to a total of 736 KB. This extra memory is directly usable by DOS without further complication of a memory management program. More space is available, therefore, for loadable device drivers, TSR programs, and/or larger application programs.
FMT1000 Series Programmer’s Guide • HIDOS.SYS, the simpler of the two, is the one which must be used if Expanded Memory is also required. HIDOS.SYS provides no UMB support. • The second Extended Memory Manager is LPHIMEM.SYS. In addition to XMM and HMA, this driver implements UMB storage, allowing use of DEVICEHIGH and LOADHIGH commands from DOS. LPHIMEM.SYS is incompatible with Expanded Memory. EMM is implemented by the driver PCCEMM.SYS.
FMT1000 Architecture Display Programming As can be seen from Figure 1-1, the LCD display is connected to the LPT1 port of the CPU via the I/O chip. This considerably eases the use of the display, since any program capable of writing to LPT1 can write to the display. A modified version of the standard BIOS Int 17 function is provided for this service.
FMT1000 Series Programmer’s Guide Additional functions have been provided (for each function, DX=0 and all functions are in hex): Function in Hexadecimal 1-8 Description AH 10 Initialize port and LCD panel. This is an LCD specific init routine which takes the place of INT 17 FX 01. AH 11 Clear display. The display is written with white space to clear it. AH 12 Update entire display. Writes a complete 80 character buffer to the display. This pointer is in segment: offset style (ES:[DI]).
FMT1000 Architecture Function in Hexadecimal Description AH 16 Return cursor position. Returns the position of the cursor in the screen: BH=Row (0 or 1) BL=Column (0-39) AH 17 Set cursor position. Set the desired cursor position in BH and BL: BH=Row (0 or 1) BL=Column (0-39) Any value outside valid range will be ignored. AH 18 Cursor up one row. AH 19 Cursor down one row. AH 1A Cursor left one column. AH 1B Cursor right one column. AH 1C Return location of display buffer.
FMT1000 Series Programmer’s Guide Function in Hexadecimal 1-10 Description AH 20 Set new tracking mode in BL 1: 1x80 fixed 2: 1x80 follow cursor row 3: 2x40 fixed 4: 2x40 left justified, cursor in second row. A value of 10H is added to the value to set to indicate that a change of state is desired. AH 21 Report tracking position BH: row position 0..23 for 2x40, 0..24 for 1x80 BL: column position 1..39 for 2x40, 0 for 1x80 AH 22 Set tracking box position BH: row position 0..23 for 2x40, 0..
Chapter 2 I/O System Programming I/O system programming consists mainly of selecting the configuration options for the many features of the I/O coprocessor. To understand the programming, it is first necessary to understand the basic characteristics and features of the I/O. Features Much of the power of the FMT1000 Series computer, particularly for industrial and automation applications, lies in its extended I/O capability.
FMT1000 Series Programmer’s Guide - Can transmit its data directly to the keyboard port of the CPU, eliminating the need for any special programming to receive the data. • Digital Input – Two digital inputs can be configured to: - Sense whether they are “On” or “Off” - Detect a change in state and inform the CPU - Count transitions from “Off” to “On” for cycle-counting applications such as printing or machine monitoring.
I/O System Programming Basics of Coprocessor Communications Communicating with the coprocessor has two parts: • sending commands to the processor • receiving replies. As can be seen from Figure 1-1, the two processors can communicate using COM2 and the keyboard port. Sending Commands to the Coprocessor All coprocessor commands are ASCII strings, consisting of a three-character mnemonic followed by any necessary parameters. They are always transmitted via COM2.
FMT1000 Series Programmer’s Guide Many parameters accept string arguments. To embed nonprinting control characters in these strings, use the format ^, which is a two-character sequence. ( refers to the key that would be used in concert with a keyboard control key to generate the code from a keyboard.) Some commonly used values are: Sequence Meaning ^I Tab ^J LF ^M CR ^L FF ^[ Escape Note: These sequences consume two characters in the specified maximum string length for a command.
I/O System Programming • Limit the total characters to fewer than 100. This is often adequate, as most coprocessor commands are short, and the default configuration is adequate for many applications. • Synchronize with the coprocessor by including a command for which you expect a reply, and wait for the reply.
FMT1000 Series Programmer’s Guide Coprocessor Reply Format All replies coming from the coprocessor have a common format: Where: tag prefix data suffix autoenter is a single programmable character is a programmable 16-character string is a 1- to 80-character string is a programmable-16 character string is a mode that determines how a reply is terminated. Response tags, prefixes and suffixes can be used to make messages coming from the coprocessor to the CPU unique.
I/O System Programming Prefixes and Suffixes in RS-232 Auxiliary Port Operations The coprocessor manipulates strings for many operations to make the job of programming the CPU easier. When programming the RS-232 auxiliary port, consider strings to consist of three parts: • prefix • data • suffix. Auxiliary input prefixes and suffixes are used to find the actual data in a data stream and separate it for input to the CPU.
FMT1000 Series Programmer’s Guide A dialing command could then be sent using: SOWDT5551212 Creative use of auxiliary prefixes and suffixes can greatly ease the job of interfacing to external devices. In many cases, correctly setting the prefixes and suffixes for such devices as the scale above can make it possible to interface these devices as keyboard inputs with no special programming.
I/O System Programming I/O Processor Commands The subsequent pages contain a list of I/O controller mnemonics. Each page describes one command. Certain conventions are used for arguments: • indicate the type of information to be passed; for example indicates a string. • Ranges of numbers are indicated as numbers in broken brackets, for example <0-80>. • N/A indicates that no arguments are passed or returned.

Returns N/A Description This command discards any data waiting in the RS-232 auxiliary serial port input buffer. It is useful for being sure the buffer is empty before you expect a device to begin transmitting. Because the input buffer is interrupt-driven, other data may be left over. This obviates the need to continuously read the buffer until it is empty.

I/O System Programming Return Code Error/Status Description 1 (command error) indicates that the last command mnemonic was incorrect or inappropriately sequenced. 2 (parameter error) indicates that the parameter following the command was incorrect or inappropriate. This error can also occur if a required parameter is missing from a command. 3 (timeout error) occurs if the timeout value is exceeded; see the SOO set output timeout command.
FMT1000 Series Programmer’s Guide SPA, RPA – Set or Return Aux Passthrough Mode Format SPA 0 | 1 0=off * 1=on Summary Sets the I/O processor passthrough mode for the RS-232 auxiliary port. Returns N/A Description When passthrough is set to 0 (off), the I/O processor's prefix, suffix, and buffer length filters control the data flow from the serial port. These filters can be set using mnemonic commands.
I/O System Programming STC, RTC – Set and Return Passthrough Termination Characters Format STC Length: 3 characters Summary Sets the character string which the I/O processor will use to recognize the end of passthrough mode.

I/O System Programming Digital I/O and Counter Commands FMT1000 Series computers have two digital inputs and two digital outputs. These are often used for such applications as access control and machine monitoring. The first set of commands configure the response format, defined earlier as the format of messages from the coprocessor to the CPU, in this case for digital I/O commands. Command Description Pg.
FMT1000 Series Programmer’s Guide Note: The terminology on and off is used in regard to digital inputs. The actual inputs are optical isolators. On means that current is flowing through the isolator, and off means that no current is flowing. Also, the input circuit inverts the signal so an input that is on will return a 0 (zero).
