Specifications

The TransTerm 5C 'BASIC' Terminal is a computer programmable in an abbreviated version of the BASIC language (TTBASIC). Using it's flexible programming resources, the terminal can be adapted to a wide variety of stand-alone applications, such as data collection, activity tracking, event timing, and equipment control (optional equipment may be required). The standard unit comes with a 2-line display, 24-key keypad, serial port, time-of-day clock and 32K bytes of battery backed up program/data memory.

The Basic Interpreter operates in 3 modes:

  1. DIRECT mode - Executes a TTBASIC statement immediately.
  2. RUN mode - Executes a TTBASIC program downloaded to the TransTerm.
  3. TERMINAL mode - Emulates a dumb terminal.

The interpreter recognizes a full set of functions and statements that provide memory initialization, program control, and input/output of data. Each program statement has a preceding integer line number. The statements are stored is ascending order in the program memory.

The Display

  • Twisted nematic liquid crystal technology with 2 lines of 24 character positions each.
  • 96 ASCII characters (upper, lowercase, numeric and specials) with a blinking box cursor symbol.
  • 5x7 dot matrix 0.179" high x 0.124" wide (4.55mm x 3.15mm).
  • TTBASIC PRINT and LOCATE commands are used to print characters on the display and for cursor positioning.

The Keyboard

  • 24­key (4x6) hermetically sealed membrane key switches with Key­click for audible feedback.
  • Keyswitch travel: 0.006" ­ 0.008", Typical with actuating force: 4­8 ounces.
  • Rated life: 10,000,000 cycles per switch element.

Most of the keys generate a single ASCII character defined by the legend in the lower center position, these can be used by a RUNning program to perform special tasks. Other keys perform the following functions:

STOP - Stops a RUNning program (RUN mode) and returns control to the keyboard (DIRECT mode).

RUN - Executes a program in memory (RUN mode), if there is a program loaded.

SPACE - Generates the ASCII space code (CHR(32)).

DELETE - This key entry deletes the last character entered.

ENTER - Generates the ASCII carriage return (CHR(13)) and terminates a statement line or string input.

S1 - LEFT SHIFT - Will generate the character in the upper left corner of the key.

S2 - RIGHT SHIFT - Will generate the character in the upper right corner of the key.

The Memory

  • 32K bytes (128K optional) used for both programs and data storage.
  • The BIOS occupies the first 3K bytes of memory.
  • User's BASIC program is stored next. The maximum program size is 64K (multiple programs can be CHAINED to on the RAM disk).
  • Data arrays are stored next, followed by the RAM disk which can hold program files as well as data files, etc.
  • The maximum number of files is 254, the maximum file length is 64K, and the maximum number of records per file is 64K.
  • The entire memory is maintained by a lithium battery when the unit is turned off (3 to 5 year battery life).

The Serial Port

  • Standard: EIA RS­232C compatible, Optional: EIA RS-422, with Serial asynchronous full duplex ASCII coding.
  • Data format: 1 start bit, 7 or 8 data bits, Optional parity (even, odd, mark, space or none), 1 stop bit.
  • Baud rates: 110, 150, 300, 1200, 2400, 4800, 9600, 19.2K

The serial port is used to upload/download programs and data files and for data input/output under TTBASIC program control. Data is transferred as serial ASCII characters. The TransTerm has a 32­byte serial input buffer and recognizes the XON/XOFF protocol.

The RS-232 connection (DB-25F) connector. The RS-422 connection (RJ-45)

Pin Signal Description Pin Signal Description

Options

  • 128K MEMORY option provides more space for programs and data.
  • The BARCODE READER interface uses a Hewlett Packard wand interface (5 pin DIN) to connect wand/pen type readers, handheld laser and D scanners, and barcode card readers.
  • Nine different barcode symbologies are supported including Code 39, UPC, EAN, Code 128,  Codabar, Interleave 2 of 5 etc.
  • A special WALL MOUNT enclosure option is available with a barcode card reader below the keypad.
  • A MAGNETIC STRIPE CARD READER (MSCR) interface is available to attach a MR-211 read-only head. The interface converts Track 2 data into ASCII under TTBASIC program control (Track 1 reader also available).
  • A special EXTENDED enclosure option is available for MSCR reader mounting above the display.
  • The optional AUXILIARY SERIAL PORT adds a bi-directional EIA RS-232C (DB9F) serial port that can be used for I/O to an external device such a printer, modem, scale etc, under TTBASIC program control.
  • The TOUCH MEMORY READER option reads Touch-key ID tags which provide a more durable identification alternative to bar coded badges.
  • The RELAY OUTPUT option (either 2 or 4) can be added for program control outputs to open a door, ring a bell, turn on a machine etc.
  • The DISPLAY BACKLIGHT option illuminates the display for viewing in the dark.
  • The BATTERY POWER option installs Ni-Cad cells to power the unit for portable operation. The power adapter is used as a battery charger. This option could also be used to provide backup power during a power outage.
  • A LOUDER beeper or L.E.D can be installed for operator feedback (vs. the standard beeper) in noisy environments.
  • A 220VAC power adapter is available in place of the standard 110VAC adapter.
  • CUSTOM OVERLAYS can be provided for high volume re-sellers with special needs, or the keypad can be customized using the optional Windowed overlay along with a custom legend sheet.
  • Tilt Bracket (image)
    The tilt bracket mounts to the back of the TT5 to provide an elevated angle for operation. Can be mounted to a wall as well as a desktop surface.
  • NEMA Rated Enclosure (image)
    The NEMA enclosure provides a reinforced steel casement for exceptionally rough environments.

A TTBASIC Developer's Kit

A Developer's Kit is available for a DOS based PC or PC compatible computers. Programs can be written, debugged, uploaded and downloaded from the PC. The kit includes a cable and a diskette containing a utility program, documentation, and sample TTBASIC programs and routines.
