CNV-1000 Converter Setup Guide

Introduction

The CNV-1000 is an ethernet to RS-485 converter that is required for communication to the BioSync readers/network. The converter is used to scan for and detect the BioSync readers via their serial number/MAC address - so no addressing of the readers is required during setup.

The host PC connects to the CNV-1000, then the CNV-1000 connects to the BioSync readers via RS-485. The RS-485 network between the BioSync units is used for fingerprint transfer and reader settings and fingerprint enrollment can be performed from any biometric unit in the network (or from the desktop USB enrollment station) - Part number (KBF-ENR1).

One CNV-1000 is required per installation (not one per fingerprint reader).

Note: The 120 ohm terminating resistor should ONLY be installed if the RS-485 communication is not stable.

Installation Notes:

• The maximum numbers of BioSync readers on a single RS-485 line is 31.
• More than 31 fingerprint readers requires an additional CNV-1000.
• The RS-485 line should be wired in the form of a continuous daisy-chain, NOT as a star configuration.
• The shield of the RS-485 line between two devices should be connected to the Earth at ONE side of the data line.
• The maximum cable run distance of the entire RS-485 network is 1000m/4000 feet.
• The recommended cable type for the RS-485 network is Belden 9501 (or equivalent).
• If you have a long RS-485 network (for example; more than 400 feet) or a large number of BioSync controllers on a single network, you should terminate the network at one or both ends of the line (but ONLY if the network communications is unstable). There is a 120 ohm termination resistor supplied for terminating the network at the BioSync and a jumper and two pins for terminating at the CNV-1000.

Note: There is no maximum number of portals that can be added to the software.
A system can use any number of CNV-1000 converters.

The following steps explain how to setup the CNV-1000 converter.

CNV-1000 Hardware Connection

3.1 Connecting a Single BioSync Reader to a CNV-1000

Important Note: As the CNV-1000 converters have the same default static IP address (192.168.1.100), if you are setting up multiple CNV-1000s, you should connect them to the network one-at-a-time. Configure the first CNV-1000 with its new IP address before you connect a second CNV-1000 module to the network.

The CNV-1000 converter is connected to the PC via a local area network (into a network hub or switch) or directly from the host PC (using a cross-over cable). It uses an external 12VDC power supply and does not require any drivers to be installed.

5. Continue the RS-485 daisy-chain connection to other BioSync readers.
6. Wire the BioSync readers into the RIMs (which should be configured for Wiegand).

CNV-1000 Host PC Connection

IMPORTANT: The CNV-1000 has a default IP address of 192.168.1.100 so for initial connection and configuration you will have to set the host PC with an IP address in the same IP range:

Consult an IT professional if you require assistance changing the host PC IP address.

1. From Windows Control Panel, go to Network and Sharing Center.
2. On the left-side of the screen click on Change Adapter Settings.
3. Right-click Local Area Connection and choose Properties.
4. Highlight Internet Protocol Version 4 (TCP/IPv4).
5. Click the Properties button.
6. Verify that Use the following IP address is selected.
7. Enter an IP address on the range of 192.168.1.X (but not 192.168.1.100).
8. Press the tab key and the Subnet mask should auto-infill with 255.255.255.0
9. The default gateway fields should be left blank.
   
   
   
   
10. You will now be able to connect to the CNV-1000 via a web browser.

CNV-1000 IP Address Change

1. Open a web browser and in the address bar, enter the default IP address for the CNV-1000.
   
   
   
   
2. A login window will appear prompting you for a user name and password.
   
   - Default user name = admin
   - Default password = 00000000 (eight zeros)
