Introduced in 1985, the TRANSTERM 5 remains one of today's most economical solutions to industrial data entry applications, particularly when both key­entry and bar code scanning are required.

In such applications as employee time and attendance, work flow tracking, inventory and job cost control and reporting, the TransTerm 5 has the flexibility to adapt to almost any application specific demands found in industry today.

The TransTerm 5 is small and easy for those without computer savvy to operate due to its efficient and simple layout. The two line, 48 character LC display has ample capacity for computer generated prompts and instructions as well as for operator entered data to be simultaneously displayed.

The unit is built of aluminum to withstand harsh environments and handling, and the hermetically sealed membrane keyboard is full­sized and unaffected by grease, and most chemicals and solvents. The keyboard includes eight programmable function keys, permitting the unit to be easily adapted to varied needs.

The standard RS-232 communications interface provides the means to directly connect the TransTerm 5 to most computer systems. Plus, the optional RS-422 TNET interface allows up to 250 terminals to be connected on a common network into a central network controller which then hooks to the host computer via an RS­232 communications port. Also available is an off­the­shelf data collection program called WINNET for a WIN 9x / NT type computer which can shorten implementation time. There are also numerous third-party sources for turn-key application software which are compatible with the TransTerm 5 as well as other models of our terminals


The TransTerm 5 operates in one of 3 Operating Modes:

  1. Teletype (TTY) mode - Displayable characters transmitted to the serial port are displayed. Keyed in, or scanned (displayable) characters are immediately transmitted out the serial port (and optionally displayed).
  2. BLOCK SEND mode - Displayable characters transmitted to the serial port are displayed. Keyed in, or scanned (displayable) characters are displayed and not transmitted until a ENTER "CR" is input. Scanned data can be set to automatically "ENTER".
  3. TNET Multidrop mode - Used with the ComputerWise TNET data collection system where up to 250 terminals communicate real-time with a single host computer. The host communicates with the TIM1B Network Controller using RS-232. The Terminals communicate with the TIM1B using RS-422 (individually addressed). The TNET system optimizes communication speed, prevents message collisions, and simplifies the communication with the host.

In all three modes, the TransTerm 5 recognizes various ASCII control codes and numerous ESCape sequence commands received in the serial port or entered via the keypad.


Super­twist Liquid Crystal Technology ­ Two lines of 24 columns with 93 displayable ASCII characters (upper case, lower case, numeric and special symbols) in a 5 x 7 dot matrix font. Character size .179" high by .124" wide (4.55mm x 3.15mm). Blinking Cursor symbol. Variable contrast control from the keyboard or by ESCape command. Optional EL backlight available.


  • 24­key (4x6) hermetically sealed membrane key switches with 0.750 inch 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 alpha-numeric keypad supports numeric (0-9) and 8 function keys (F1-F8). Shift keys (S1 & S2) are used for entering Capital alpha (A-Z), a few special symbols, and ESCape. A special HEX key can be used for entering any ASCII character. Other keys include:

CLEAR - Clears the display buffer (Generates a CAN code CHR(24))

DELETE - This key entry deletes the last character entered (Generates a Delete code CHR(127)).

ENTER - Terminates a statement line or string input (Generates a Carriage Return CHR(13))

SPACE - Moves the cursor one space to the right (Generates a space code CHR(32)).

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

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

Eight Function Keys

Keys F1-F8 can be programmed to hold from 1 to 14 characters each. The codes generated by the function keys can be regular displayable ASCII characters or Control Commands.


The standard RS­232 communications interface allows the TransTerm 5 to be easily interfaced directly to any host computer which has a serial communications port. The optional RS­422 compatible TNET interface allows the TransTerm 5 to communicate point­to­point over long cable runs, or to be multi­dropped in a network with other like devices under control of the TNET polling protocol which is inherent in the ComputerWise TIM1B network controller. Up to 250 terminals can be supported on a TNET system. Off­the­shelf data collection software for PC/AT/PS2 computer systems can minimize implementation time and expense.

Barcode Decoding Option
The bar code decoding option adds the electronics and a panel mounted connector to the TransTerm 5 for interfacing a digital wand, barcode badge reader, or any laser or CCD scanner which has on-board decoding and wand emulation output. The decoding option will autodiscriminate Code 39, Extended Code 39, UPC­A, UPC­E, EAN­8 EAN­13, CODABAR, I2of5, and Code 128. Each of these symbologies can be enabled/disabled under SETUP or program control. The bar code port has a 5­pin DIN connector.

Magnetic Stripe Card Reader Interface Option
The Magnetic Stripe Card Reader (MSCR) Interface Option for the TransTerm 5 adds the electronics to receive and decode digital data from the MR­211 manually operated reader which can read the magnetically recorded information found on Track 2 of a standard ABA plastic credit card (F2F coherent phase encoding per ANSI X4.16). The MSCR interface reads the 40 digit numeric data record off the card as it passes through the read station, decodes and validates the data, and then passes the data internally just as if it had been key­entered from the keyboard. The MSCR interface normally connects to the MR­211 reader with a six inch cable.

Auxiliary Serial Port Option
This option adds a second serial communication port to the TransTerm 5A or 5C which is controllable with ESCape commands from the host computer. The baud rate and hand­shaking are also user's selectable via Setup. The auxiliary port for the 5A uses a 5­pin DIN connector and the 5C uses a 9-pin D-sub connector (standard AT port pin-outs) This port might typically be used to output data to a serial printer or input data from a scale. The 5A port is available in lieu of the bar code port,; whereas, the 5C port is available in addition to the bar code port.

Pulse Output Option
This option enables the TransTerm 5A or 5C to generate a programmed pulse output under control of ESCape commands received by the terminal through the communications port. This option could be used to actuate a door strike or a cash drawer, etc..

Counter Input Option
This option enables the TransTerm 5A or 5C to count and totalize closures of an external dry contact switch input. The count value can be interrogated and zeroed remotely by ESCape commands received by the terminal through the communications port.
