The TransTerm 9B is an RS232 compatible ASCII
keyboard/display data terminal designed for applications which require a large number of
keys which can be user configured. Typical applications include: pointofsale register
emulation, restaurant order entry systems, shopfloor menu selection, quality control
The TransTerm 9B features a 72key sealed membrane
keyboard array and a two line by 40 character alphanumeric liquid crystal display. The
entire 72 key array can be user defined as to the legend which appears on the key surface
(each key position having a clear window) as well as the unique ASCII code which the key
is to generate when pressed. Additionally, any key can be designated an
"autoENTER" key and thereby produce an "ENTER" code immediately
following the assigned primary code when that key is pressed.
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 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 RS232C communications
interface provides the means to directly connect the TransTerm 9B to most computer systems.
Or, the optional RS422 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 for a PC/AT/PS2 type computer which can shorten implementation time.
The TransTerm 9B can operate in one of three
- TTY Mode
- BLOCK SEND Mode
- TNET Multidrop Mode
In TTY and BLOCK SEND modes, ASCII data received
by the TransTerm 9B 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 (depending on
how the keyboard array has been programmed (downloaded) is transmitted as it is keyed. In
the BLOCK SEND mode and in the TNET multidrop mode, keyed data is locally placed on the
display and transmitted only after the ENTER key is pressed. In the TNET multidrop mode,
the TransTerm 9B 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.
Supertwist Liquid Crystal Technology Two
lines of 40 columns with 93 displayable ASCII characters (upper case, lower case, numerics
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.
75 key membrane keyboard organized in a main
array of 6 rows by 12 columns. The all 72 keys in the array can be downloaded by the host
computer (one code per key). A separate "ENTER" key and two shift keys are
located to the right of the main array. Other features are:
- Hermetically sealed keyswitches.
- Audible keyclick for tactile feedback.
- Key spacing .8" vertical, .75"
- Keyswitch travel .006" .008"
- Actuating force 46 ounces.
- Rated life 10,000,000 cycles (per switch
The standard RS232 communications interface allows the TransTerm 9B to be easily
interfaced directly to any host computer which has a serial communications port. The
optional RS422 compatible TNET interface allows the TransTerm 9B 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 TIM1 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 9B for interfacing a digital wand, a barcode
badge reader, or any laser or CCD scanner which has onboard 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
Magnetic Stripe Card Reader Interface Option
The Magnetic Stripe Card Reader (MSCR) Interface Option for the TransTerm 9B 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 9B which is
controllable with ESCape commands. This option for the 9A is in lieu of the bar code
option, and for the 9B model it is available in addition to the bar code option. The baud
rate and handshaking are also user selectable via Setup. The auxiliary port on the 6A
has a 5pin DIN connector and the port on the 6B has a 9pin Dsub connector (pinouts
are compatible with an AT com port) and 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 9B 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 open a cash drawer, etc..
Counter Input Option
This option enables the TransTerm 9B 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
