Connection options in an Ethernet network

There are 2 main approaches to establishing a connection between your host and the readers:

  • Client: The application acts as a client and opens a connection to the passively waiting readers.
  • Server: The application acts as a server that waits for readers to open a connection when certain events occur.

The following table shows you when to use which approach and gives you an overview of your implementation options.

 

Client

Server
Connection initiation The host opens a connection to the readers. Readers open a connection to the host in certain events.
Network topology

Use this approach if your network meets both of these conditions:

  • Manageable number of readers

    Parallel threads can be maintained without performance loss.

  • Readers not behind a firewall

Use this approach if your network meets either of these conditions:

  • Large number of readers

    Parallel threads will impact host/network performance.

  • Readers are behind a firewall
Reader detection Only needed for deployment of initial network settings via BALTECH Uploader (see below). After that, readers establish connections to the host.
Deployment of initial network settings
  • Via BALTECH Uploader
    Note: This tool always runs in Ethernet client mode and thus needs to be able to detect the readers. This is an option in the following cases:
    • You run Uploader in the same subnet as the readers and detect them via SLP.

      This currently requires PKI encryption.

    • Readers use known static IP addresses.

      This currently requires PKI encryption.

    • You connect the readers in maintenance mode before installation.
  • Via ConfigCard
  • Via host application
    Note: Readers need to find the host via UDP introspection. This is an option if both of the following apply:
    • Readers are not protected by a firewall.
    • Each reader is connected to a PC (or another network device) with a known IP address.
Operation modes Use any mode. Pick the one that suits your requirements best. Readers must be set up for autonomous operation. Use one of the following modes:
  • Autoread

    to read a number

  • VHL & Autoread

    to read data other than a number, write data, or format cards

All modes include step-by-step instructions on setting up the host-reader connection.
