Transterm \’BASIC\’ Programmable Terminal

Overview

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.

Basic Interpreter

The Basic Interpreter operates in 3 modes:

DIRECT mode – Executes a TTBASIC statement immediately.
RUN mode – Executes a TTBASIC program downloaded to the TransTerm.
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.

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.
5×7 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.

24key (4×6) 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.

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).

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

3 RD	Receive data Input 3 DTD+ Transmit Data (+) Output
4 RTS	Request to send Output 4 DTD- Transmit Data (-) Output
5 CTS	Clear To Send 5 DRD+ Receive Data (+) Input
7 GND	Ground 6 DRD- Receive Data (-) Input
20 VIN	Power supply in (12 VDC) 7 GND Ground
8 VDC+	+12 VDC Supply Input (Opt)

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.

Power

Terminal consumption: 150 ma typical (various options will add to the power consumption).
