TT7C Datasheet (166k/PDF documents require Adobe Acrobat Reader pdf)

THE TRANSTERM 7C is a hand-held portable battery powered data collector. This general purpose device can be used for physical inventory, route accounting, order entry, and general purpose data collection. The unit is built to withstand harsh environments and handling. The keypad is unaffected by most chemicals and solvents and the large keys are easy to press even with gloved fingers. The 32 character display is suitable for operator prompting and displaying operator entered data. Also available is the TT7B which functions as a basic ASCII portable data collector . Please contact us for more information.

Operation

  1. The TransTerm 7C "PROMPTS" the operator to enter data (presents instructions for data entry to the display).
  2. The operator inputs alphanumeric data via the keypad or using the optional barcode scanner.
  3. The data is displayed and optionally validated (a validation file and/or string can be programmed into the TransTerm 7C).
  4. The TIME and/or DATE can be optionally appended to each entry or to each sequence of prompts.
  5. The data is stored in memory (The "Arrow" keys can be used to review and/or edit the data in memory).
  6. The data is later uploaded to a host computer (either directly connected RS-232 or remotely connected through an external modem).

Selectable Features

  • Up to 20 user defined PROMPT messages can be downloaded to the TT7C using menu driven PC software.
  • The Validation for each prompt can be user defined and downloaded with menu driven PC software (Validation is optional).
  • The data upload can be initiated from either the host computer or from the TT7C.
  • The Function Keys (F1-F8) can be pre-programmed to hold 1 to 12 characters each (displayable ASCII characters or Control Codes).
  • The TT7C can be configured with a unique address (to independently upload from multiple units).
  • Using a pocket modem, the TT7C can transfer collected data from remote locations.

Display

  • Super twisted nematic Liquid Crystal technology with 2 lines of 16 character positions (5 x 7 dot matrix font 0.189" high x 0.118" wide).
  • Supports 96 ASCII characters (uppercase, lowercase, numerics, plus 32 special characters) with a blinking box cursor symbol.

Keyboard

  • 32­key (4x8) hermetically sealed membrane keypad with 0.750" wide x 0.562" center-to-center spacing and Key­click for audible feedback.
  • A WINDOWED polycarbonate overlay allows a printed key legend to be inserted between the keyboard and overlay to label the keys.
  • Keyswitch travel: 0.006" ­ 0.008", Typical with actuating force: 4­8 ounces (Rated life: 10,000,000 cycles per switch element).
  • The keypad supports 8 function keys (F1-F8), numerics (0-9) and Alphas (A-Z) (A/N key is used to toggle from Numeric to Alpha key entry).
  • Other keys include; ENTER, CLEAR, SPACE, DELETE, STATUS (memory, battery & time) and SETUP (configuration & data transmission).

Memory

- The standard TransTerm 7C holds 128K bytes of collected data, Optional memory sizes include; 256K, 384K, 512K, 640K, 768K, 896K, 1024K and 1152K. The memory is protected by a 3V lithium battery (5 year rated life).

Serial Port

  • EIA RS­232C compatible with Serial asynchronous full duplex ASCII coding.
  • The TransTerm recognizes both hardware and software handshaking (XON/XOFF).
  • Data format: 1 start bit, 7 or 8 data bits, Optional parity (even, odd, mark, space or none) and 1 stop bit.
  • The TransTerm supports eight baud rates: 110, 150, 300, 1200, 2400, 4800, 9600, 19.2K

The RS-232 connection is a DB-9M connector with the following signals:

Battery Power

The TransTerm comes with four AA size Ni-Cad batteries and a battery charger. Typical battery life is 10 to 20 hours with a full charge (varies with options). The battery charger connects to a standard 110VAC outlet, and plugs into the side of the TransTerm.

Options

  • The BARCODE interface is a Hewlett Packard wand interface (5-pin DIN) to connect a wand/pen, handheld laser, CCD scanner or barcode card reader. Nine different symbologies are supported: Code 39, Extended Code 39, UPC, EAN/JAN, Code 128, Codabar and Interleave 2 of 5.
  • The TOUCH MEMORY interface reads Touch-key ID tags in place of the barcode reader. These small metal micro-cans provide a more durable alternative to bar coded badges (micro-cans are typically attached to a key chain).
  • The DISPLAY BACKLIGHT option illuminates the display for viewing the TransTerm in the dark.
  • CUSTOM OVERLAYS can be provided for high volume re-sellers with special needs (OEM applications).
  • The optional PROTECTIVE CARRYING CASE has a loop to hang the unit from a belt and a holster for the barcode wand.

Utility Software

Utility Software is available for uploading, downloading and terminal configuration. The TT7CUP Utility Program interfaces the TransTerm with an IBM PC/AT or compatible computer using COM1 or COM2. Contact ComputerWise for more information on interfacing and application implementation.
