Tranz 330 operations manual

To try to fix a clock that is not transmitting during the automatic midnight transmit, press [9] to transmit the punches then reprogram the clock.

If it still fails to dial at night, you can attach an analog phone to the line and check for static or feedback on the line that may be causing interference. You can also try the clock on another analog line or from another location over night to see if it will transmit. This will check to see if a clock might not auto-dial because of noise on the line static.

It does not apply to Ethernet-based clocks. While the serial number will be displayed on the clock and it's box, you can read the serial number from the clock's display as well.

No, the clock can collect the employee punches without being plugged into the phone line and can store up to punches before it will need to transmit the data, but for the transmission of punches to take place the clock will have to be plugged into an analog phone line. This will display the dialing prefix and the number it is currently dialing to transmit punches to our server.

Yes, the clock will update when the clocks change, however, this instruction comes from our servers, not from the clock itself. In order to force the adjustment, it is best to press "9" on the clock and transmit the clock before punching in after the time change. If your clock is unable to dial into our servers, it can store up to 2, punches before it reaches capacity. The clock will dial out at least once per day automatically to transmit punches, usually late at night.

To find this on the clock press FUNC then '2' then '4' and it should display how many punches are currently saved on the clack that need to be transmitted. A special diagnostic mode is available on the SwipeClock Tranz and Tranz The screen will display "diagnostics". Press [4], and it will say "swipe card now.

Keep in mind that the clock will display the normally unseen prefix of "", in addition to the 8-digit card number. Voice Over IP lines can occasionally recognize fax or data transmissions but it has been our experience that our analog clocks will not work on VoIP lines.

We suggest that you use an Ethernet clock in it's place. Privacy Policy. Skip to Main Content. Home End-user Help Centers. Expand search. Search Search. Information Title. At the CPU interface, the card reader signal is normally 1 when no card is present, and toggles rapidly between 1 and 0 when a card is swiped. A track on the magnetic stripe consists a long series of magnetic domains. Each domain is polarized magnetic North or South.

When the read head is over a domain of either polarity, the card reader signal is 1. When the read had passes over the boundary between domains of opposing polarities, the card reader signal briefly pulses to 0. The duration of this pulse is approximately 40 microseconds. Each logical data bit on a track has the same physical length on the magnetic stripe. There will always be a magnetic domain boundary at edge of a bit.

A logical 1 bit will also have a magnetic domain boundary within the length of the bit, but a logical 0 will not. Two successive pulses each time N since the last represent a logical 1, and a single pulse time 2N since the last represents a logical 0.

This encoding format is called F2F or Aiken Biphase. For better reliability, the card reader library routine also adjusts the value of N during bit transcription, to compensate for an accelerating or decelerating motion during the card swipe. The OKI MB real-time clock provides a mechanism to query and update the second, minute, hour, day, month, and year.

Because the Tranz has an internal backup battery, the date and time is retained even when external power is lost. The 73KL-IP single-chip modem provides a bps interface for communication over dial-up phone lines. Complete details on using the modem can be found in the 73KL datasheet. If you find this technical information useful, and make a cool project based on the Tranz , please leave a note in the comments!

I ended up using a time constant of and scale factor of 1 to get me to baud. Actual baud is but it seems close enough. Not long ago, I picked up an old point-of-sale terminal at an electronics surplus store. After discovering a cool little Z based computer inside, and reverse-engineering the hardware, I decided to reprogram it to unlock the music hidden inside magnetic stripe cards. The and its cousins are great for electronics tinkerers. They use the same microprocessor as the TRS and ZX Spectrum, so handy software routines from those computers can be reused.

Documentation for the is readily available online, but it only addresses how to use the POS features, with very little hardware information. After due consideration and a couple of beers , I decided to make a demo that reads data from magnetic stripe cards, and uses it to play music. What song does your Visa play? When a card is swiped, the card reader returns the ISO Track 2 data, which is up to 40 BCD characters, with 4 data bits and 1 parity bit per character.

The raw data uses F2F encoding, in which all bit intervals are the same duration, but a logical 1 has a low-to-high or high-to-low transition during the bit interval, and a logical 0 has the same polarity during the whole bit interval. This F2F signal must be converted into binary data in software. Once the card data has been read, a rule-based system is used to turn it into semi-acceptable music. Converting the card digits directly to notes only generates random beeping, so a more complex system based on the ideas from the Melisma Stochastic Melody Generator was used.

The Mozart music engine generates random melodies with a given key, mode, length, tempo, interval size range, and other parameters from music theory. The parameters are used to construct a set of probability tables, which are then multiplied to construct the final table used to randomly select the next note. If the card expires soon, it plays a minor melody — spooky! The key — F, B-flat, whatever — is determined by the month of expiration. There are twelve months in a year, and twelve semi-tones in an octave, so it was a perfect fit.

The number of data bytes on the card determines how many measures of music are played. A credit card will play a longer melody than a grocery club card. It prints my name on the display! I may faint from the excitement. Until then, here are some of the minor problems I ran into, in addition to the job of reversing the hardware design:. Two pins are swapped. What the heck? It turns out I probably should have gotten a 27SF instead, which is a 64K part, but is drop-in compatible as long as you put the 32K image in the upper half.

I could almost fix my pin mismatch by bending some pins and adding some jumper wires, but modifying the 28C would prevent me from reprogramming it later. Ah, quality. I found an old credit card terminal at an electronics surplus store recently, and bought it to tinker with. Inside is a simple, self-contained 8-bit computer with a lot of hacking potential.

The Tranz has a 16 key keypad, 16 character vacuum flourescent display each charachter with 16 alpha-numeric segments , and a serial port with an 8 pin DIN connector. It also has an internal modem, a pair of telephone jacks, and a specialized 6 pin DIN serial port intended for use with peripherals. If you have several terminals to program, you must set up a "master" terminal first, which will require the greatest load time.

Subsequent terminals can be programmed more quickly from this master terminal. Enter the password provided by VeriFone when you purchased the terminal or terminals. It should be Z for Tranz models. If you only have one Tranz terminal, proceed to Step 3. Slide a customer's credit or debit card through the Tranz 's card reader, with the magnetic stripe to the right and facing down. The display will display "Processing", then "Transaction successful" or a variety of reasons for the card being declined.

If the terminal beeps after swiping the card, you must slide it again. If it continues beeping, manually enter the card information, described in Step 4.
