Getting to know the BioPointe Chapter 1 1 Getting to Know The BioPointe Introduction The BioPointe is a fingerprint identification device designed for use in access control. It relies on 3 LEDs to convey status information to the user. Depending on the color and speed of the blinking LEDs, different statuses are conveyed. 1.1 How The BioPointe Works Types of Authentication Properties The BioPointe is able to perform three types of authentications.
Getting to know the BioPointe Local Enrollment and Central Enrollment The system is designed to cater for both local and central enrollment. By central, it means that the users of the device are enrolled centrally on a host PC. Their authentication properties are then downloaded by means of a communication link, to the BioPointe. Central enrollment requires the use of the central enrollment software, known as BioPointe Central.

Getting Started 2.5 Mounting The BioPointe The figure below shows how the BioPointe can be mounted using the C-bracket.
Features Chapter 3 3 Features The BioPointe functions are designed as an access control device aimed to provide irrefutable personal identification using fingerprints. Its system architecture includes the fingerprint identification technology, the recording of event logs, the interfacing to security panels and so on. In this chapter, you will learn about the variety of features that make up the system.
Features 3.1 Authentication and Managing Authentication Properties The BioPointe is designed to refute unauthorized access using fingerprint authentication. However, the device also caters to the use of a non-fingerprint medium. As you have seen briefly, the BioPointe also supports the use of card only and card with PIN authentication. The type that is being used is defined during the enrollment process.
Features Multiple Fingerprint Verification In usual operation, the BioPointe only matches a single fingerprint to successfully pass a verification process. However, it can be configured to match two or even three fingerprints before a verification process can be considered as successful. In such a mode, the user has to enroll this ID with the same number of fingerprints that it is matching with, or more.
Features 3.1.2 Card Authentication Besides fingerprint authentication, you are also allowed to enroll the user to authenticate using a contactless card combined with a PIN or just the contactless card alone. Every contactless card carries a unique ID. The security level provided by this mode of authentication also depends on the type of card being used. Some cards store more (or unique) information than the others.
Features 3.2 Local Administration from Device Local administration means tasks can be performed at the device without the need for a host program. Master Authentication Before any of these tasks can be performed, a master authentication is first carried out. The master authentication allows the device administrator to enter the device administration mode, which permits the device administrator to register new Master or User and access the device basic configurations.
Features 3.3 Remote Administration from Host Program The BioPointe device provides two modes of communication channel so that the remote PC can connect to the device to perform administrative function and upload log records from the device. The serial interface supports the RS232, RS485 and RS422 specification. In order to prevent unauthorized access to the device from remote PC, the authentication protocol is added to the communication protocol.
Features 3.4 Logging of Transactions and Trace Events The BioPointe device handles three types of log records listed as follows: • Transaction Log A transaction log is recorded upon a successful Door Access Authentication or Door Access Authentication Time-Zone Control. Each log contains the ID of the user performing the authentication, as well as the date and time.
Administering the BioPointe Chapter 4 4 Administering The BioPointe Introduction This chapter describes how you can perform a range of administration tasks from the device. For example, you can enroll authentication properties, or have them deleted from the device.

Performing Authentication with the BioPointe Chapter 5 5 Performing Authentication With The BioPointe This chapter assumes that you have already learned how to enroll the authentication properties. If you have not learned how to do so, you may like to look at Chapter 4 – Administering the BioPointe again. This chapter describes how your fingerprints and other authentication properties can be enrolled locally on the device.
Performing Authentication with the BioPointe 5.1 Performing Fingerprint Authentication There are 4 ways to perform fingerprint matching. The first is to use the keypad to enter your full ID. The second is to present your full ID to the BioPointe through the hidden card reader by flashing the card across the device. These 2 methods are also known as one-to-one-matching (verification). The third method is to use Quick Search.
Performing Authentication with the BioPointe One-to-One Matching using the Card Reader 1 2 Flash your card across the device. (Your card ID must be the same as the UserID enrolled previously.) If the ID exists, the sensor will light up and the 2nd LED will blink fast in red. Place your finger on the sensor, removing it only when the sensor light goes off. 3 If the 1st LED lights up in green, the authentication is successful. If the 1st LED lights up in red, you will be allowed another try.
Performing Authentication with the BioPointe Quick Search Quick search eliminates the need for you to enter your full ID. This is useful if the number of digits you organization used for the ID is long, making it hard for the staff to remember the full ID. With quick search, what you need to do is to enter just 2 or more digits of your ID from the back and then hit the first function key to initiate the matching process.
Performing Authentication with the BioPointe One-to-Many Matching (or Identification) With one-to-many matching, you need not remember your ID. However, the user must note that this matching process is carried out at a higher security level. Before one-to-many matching can be used, the mode must first be enabled. To enable this mode, you can refer to Chapter 4 – Administering the BioPointe.
Performing Authentication with the BioPointe 5.2 Performing Card Only Authentication 1 Flash your card across the device. (Your card ID must be the same as the UserID enrolled previously. In addition, this card ID must be enrolled as the Card Only authentication property.) 2 If the 1st LED lights up in green, the authentication is successful. If the 1st LED lights up in red, the authentication fails. (This could be because the ID was not found within the device.) 5.
Configuring the BioPointe Chapter 6 6 Configuring The BioPointe This chapter describes how DIP switch settings can be made and how the serial and Wiegand cables can be wired to the BioPointe control board. 6.1 Location of DIP Switches and Connectors Tamper Switch located within Dip Switch SW1 Dip Switch SW2 Dip Switch SW3 Power and Communication Cable Connector (12 way) 1 2 3 4 5 6 7 8 PIN No.
Configuring the BioPointe 6.2 DIP Switches There are three DIP switches on the control board. The usage of each switch is as tabulated: SW1 SW2 SW3 8-way 4-way 8-way To set the Device ID To set the baud rate and communication type To set the type of serial communication (i.e. whether RS232, 422 or 485) The following tables show the settings for each of the three DIP switches. Note that a "-"indicates an "OFF" position. Table 1: SW1 (Device ID) SW1 is used to set the Device ID of the device.
Configuring the BioPointe Table 2(a): SW2 (Baud Rate) SW2 has a row of 4 DIP switches. Two is used to determine the baud rate while another two is used to indicate the communication type. Switch / Baud Rate (Bps) 38400* 19200 9600 2400 *- Default setting 1 2 ON ON ON ON - Table 2(b): SW2 (Communication Type) The communication type is a setting that lets the BioPointe know how to respond to incoming data from the host.
Communicating with the BioPointe Chapter 7 7 Communicating with The BioPointe The BioPointe supports 4 types of serial communication i.e. RS232, RS485, RS422 and Modem. When you have decided which type of serial communication interface to use, make sure that each cable is inserted correctly at the location that corresponds with the signal type. In addition, you also need to configure the BioPointe to the correct type of serial interface and the correct type of baud rate through DIP switches.
Communicating with the BioPointe Step 1: Power off device Connect the pair of power supply wires as shown in the figure below. Ensure that the location of each wire is correct. Keep the device powered off so that any wrong connection later will not damage the device.
Communicating with the BioPointe [NOTE] In RS422/485 mode, it is necessary to install termination resistors at both ends of the communication lines. The value of each resistor should equal the characteristic impedance of the signal wires (approximately 120 Ohms). No resistors are installed at the factory. Step 3: Configure type of serial interface with SW3 The BioPointe supports three different signal types – RS232, RS422 and RS485.
Communicating with the BioPointe Step 5: Setting the Device ID SW1 is used to set the Device ID of the device. It has a row of 8 DIP switches. The range of Device IDs that can be set is 0 to 255. However, the acceptable range for field operation is 1 to 254. The Device ID is set according to the binary format of an 8-bit byte. An "ON" position is interpreted as binary bit 0. To help you to find the dip switching settings for a particular Device ID, use the index value associated with each bit.
Communicating with the BioPointe 7.2 Tips for Ensuring Good Communication Communication faults are problems that are commonly faced during field setups of RS485 and RS422 networks. To alleviate the occurrence of problems, do take note of the following points: • • Obtain good communication cables. The Beldon 8102 (4-core) is the recommended cable to use. Ensure that wire tips are soldered-tinned and seated securely in the connector of the device.
Communicating with the BioPointe 7.3 Troubleshooting Communication Problems The table below describes some of the problems that are commonly faced and what you can check to resolve them: 1 Error reported at TDM software program Error code 203 (CB hex) – Zero byte received Description of Error Items to check Device does not respond 1. 2. 3. 4. 5. 6. 2 Error code 199 (C7 hex) – Receive header wrong Some garbage was received 1. 2. Error code 198 (C6 hex) – Receive footer wrong 3.
Communicating with the BioPointe 7.4 Communication using Modem Communication using the modem is supported in the BioPointe for one device as well as with multiple devices. If the modem is connected to only one device, the signal type is RS232 in nature. The SW2 setting for communication type has to be "Modem" for this device. If the modem is connected to multiple devices in a multi-drop network, the signal type will be either RS485 or RS422 depending on which is chosen.
