The TransTerm 6 is an economical solution to alphanumeric data entry applications where small size and light weight are important considerations. Diverse industrial data collection requirements such as employee time and attendance, work flow tracking, and inventory and production control are but a few of the uses to which the TransTerm 6 can be applied. The TransTerm 6 is small and easy for untrained personnel to operate, its not "intimidating" to those non­computer types. The unit is built of aluminum to withstand harsh environments and handling, and the hermetically sealed membrane keyboard is full-sized and unaffected by grease, and most chemicals and solvents. The two line 80 character LC display has ample capacity for computer generated prompts and instructions as well as for operator entered data to be simultaneously displayed. The standard RS-232C communications interface provides the means to directly connect the TransTerm 6 to most computer systems. Or, 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 RS-232 communications port. Also available is an off-the-shelf data collection program for a PC/AT/PS2 type computer which can shorten implementation time.


The TransTerm 6 can operate in one of three modes:

  • TTY Mode
  • TNET Multidrop Mode

In TTY and BLOCK SEND modes, ASCII data received by the TransTerm 6 is placed on the display at the cursor position. The cursor moves from left to right and from the top to bottom. In the TTY mode, keyboarded data is transmitted as it is keyed. In the BLOCK SEND mode and in the TNET multi-drop mode, keyed data is locally placed on the display and transmitted only after the ENTER key is pressed. In the TNET mode, the TransTerm 6 must be selected with its address in order to receive and process data or send ENTERed data. In all three modes, the terminal recognizes the various ASCII control codes and numerous ESCape sequence commands.


Super-twist Liquid Crystal Technology - Two lines of 40 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. Option EL backlight is available.


53 key membrane keyboard with embossed graphics in QWERTY layout. Hermetically sealed keyswitches.

  • Audible key-click for tactile feedback.
  • Key spacing - .8" vertical, .75" horizontal.
  • Keyswitch travel - .006" - .008" typical
  • Actuating force - 4-6 ounces.
  • Rated life - 10,000,000 cycles (per switch element).


The standard RS-232 communications interface allows the TransTerm 6 to be easily interfaced directly to any host computer which has a serial communications port. The optional RS-422 compatible TNET interface allows the TransTerm 6 to communicate point-to-point over long cable runs, or to be multi-dropped in a network with other like devices under control of the TNET polling protocol which is inherent in the ComputerWise TIM1 network controller. Up to 250 terminals can be supported on a TNET system. Off-the-shelf data collection software for PC/AT/PS2 computer systems can minimize implementation time and expense.

22 DTD- RS-422 Transmit Data (-)
23 DTD+ RS-422 Transmit Data (+)
24 DRD- RS-422 Receive Data (-)
25 DRD+ RS-422 Receive Data (+)


Bar Code Decoding Option
The bar code decoding option adds the electronics and a panel mounted connector to the TransTerm 6 for interfacing a digital wand, a 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, UPC-A, UPC-E, EAN-8, EAN-13, CODABAR, I2of5, and Code 128. Each of these symbologies can be enabled/disabled under SETUP or program control. The bar code port has a 5-pin DIN connector.

Magnetic Stripe Card Reader Interface Option
The Magnetic Stripe Card Reader (MSCR) Interface Option for the TransTerm 6 adds the electronics to receive and decode digital data from the MR-211 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 key-entered from the keyboard. The MSCR interface normally connects to the MR-211 reader with a six inch cable.

Auxiliary Serial Port Option
This option adds a second serial communication port to the TransTerm 6A which is controllable with ESCape commands. For the 6A, the port is in lieu of the bar code port, and for the 6B, the port is in addition to the bar code port. The baud rate and hand-shaking are also user selectable via Setup. The auxiliary port uses a 5-pin DIN connector for the 6A and a 9-pin D-sub connector on the 6B model. The port might typically be used to output data to a serial printer, or input data from a scale.

Pulse Output Option
This option enables the TransTerm 6 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 6 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.
