Hand Punch Biometric Validation
TimeIPS can validate employee identification using biometric hand punch authentication. Employees clock in and out of TimeIPS and are asked to present their hand for validation. You can deny the clock event or send an email warning if the validation fails.
A special adapter cable is required to connect a Hand Punch unit to TimeIPS. This cable is included with Hand Punch units purchased from TimeIPS. If you already have Hand Punch units and purchased cables alone, you will need to configure your Hand Punch units to communicate with TimeIPS.
- First reset your reader. This is normally done by removing power to the Hand Punch reader, pressing and holding the reset button on the back (on older units, by setting DIP switches 4 and 5 to the "ON" position), and re-connecting power.
- If prompted on startup, reset all to defaults
- Normally the reset to defaults will allow communication to work at this point.
- If not, follow the configuration steps below:
- Enter command mode on the Hand Punch unit by pressing Clear and Enter on the keypad at the same time.
- Enter 2 for the password and press Enter. This will enter the configuration menu.
- Press the "* No" key until you reach the "Set Address" prompt. Then press the "# Yes" key.
- The address should be set to "1"
- Press the "* No" key until you reach the "Set Serial" prompt. Then press the "# Yes" Key.
- Press the "* No" key until you reach the "Set RS-232" prompt. Then press the "# Yes" Key.
- The screen should be set to "9600 baud"
You may wish to change passwords on the Hand Punch unit after configuration to prevent tampering
Upon initial setup of a new Hand Punch unit to an existing clock it is required to probe for the new device. This can be done directly at the clock by pressing Enter on the keypad to get into the system menu and logging in using the badge number of a system administrator. Use the arrow keys on the keypad to navigate to "Use Biometrics" and press Enter. On the next screen select "Auto" and press Enter once more to detect the Hand Punch unit.
TimeIPS handpunch cables must be wired correctly to the small green adapter that plugs into the back of the Hand Punch unit. If the Hand Punch unit's wiring has come loose, or if the Hand Punch unit was delivered unwired, the following diagram depicts the correct wiring. If the handpunch cable has Blue, Blue/White and Green wires, use the diagram on the left. If the handpunch cable has Blue, Green and Red wires, use the diagram on the right. Note that in the photos below, the screws used to tighten the wires are facing down.
If the Hand Punch unit is not working at all, please follow these steps:
- Power-cycle the TimeIPS clock and Hand Punch unit
- Double-check the cable connecting TimeIPS to the Hand Punch unit. Look for loose wires or connectors.
- Clean the platen with a damp cloth using a mild soap. Wipe from the back to the front. Be sure to clean the back right corner.
If the Hand Punch unit has a hard time matching hands and/or sometimes does not work, the unit may need to have the calibration checked and/or reset. Please follow these steps:
- Enter the service menu by pressing Clear and Enter at the same time. Press 1 for the password and then Enter.
- Press "# Yes" for Calibrate.
- You should see the current calibration values.
- R and C values represent the sensor image alignment. The ideal value is 0. These values should be 0 +/- 2.
- The E value represents the sensor image quality. The ideal value is 100. This value should be 100 +/- 20. Values above 120 indicate the image quality of the handprint is poor and matching may be difficult.
- You may want to write down the current calibration values for comparison.
- To perform the recalibration press "# Yes" once more.
- When the calibration process is complete press "# Yes" again.
- Compare the new calibration values against those you saw a moment ago.
- Press Clear twice to exit the service menu.
If the recalibration process does not improve the calibration values and the Hand Punch unit's recognition performance, the Hand Punch unit may have environmental contamination in the internal optical system. This can usually be repaired if the unit is sent to TimeIPS for servicing. Please contact TimeIPS support.
