How to change Antenna Ports with the Nova or SuperNova

With a Nova (or SuperNova) connected to your computer, open SkyeWare.  The reader should show up on the left hand side of the screen, under “Readers”.  As a reminder, make sure that the Nova is also connected to a 50 Ohm UHF RFID antenna.  Powering the module without an antenna connected could result in damage to the module.

Once the Nova has been detected by SkyeWare, click Capabilities -> Protocol to get to SkyeWare 4’s Protocol Builder.

The Nova uses the SkyeTek multiplexer system parameters to switch between antenna ports.  To learn more detail about the SkyeTek Multiplexers and for full examples, please see The Multiplexer Reference Guide.

1) Read System Parameter

First, verify that the Mux command is properly detected.  Use SkyeWare’s protocol builder to enter the following settings:

  • Command: Read System Parameter
  • Address: 000A (multiplexer control)
  • Blocks: 01
  • Hit the “Send” button.  The “Response” field should populate, and the “Code” field should read “Read System Parameter: Pass”.

In the example below, the request (in binary mode) is: <02>000A00201201000A0001<A4E2>, and the response was <02>00071201000100<BB7A>.  The last two digits indicate that the antenna port is currently set to port 0, the Nova’s default port.

2) Write System Parameter (to change antenna port)

To change the antenna port, set the multiplexer to port 1.  Use SkyeWare’s protocol builder to enter the following settings:

  • Command: Write System Parameter
  • Address: 000A (multiplexer control)
  • Blocks: 01
  • Data: 01 (set the antenna port from port 0 to port 1)
  • Then hit the “Send” button.  The “Response” field should populate, and the “Code” field should read “Write System Parameter: Pass”.

In the example below, the request (in binary mode) is: <02>000D08201202000A0001000101<C835>, and the response was <02>00041202<E652>.

3) Read System Parameter to verify antenna port change (optional)

To verify that the antenna port was successfully changed, you can send one more “Read System Parameter”:

  • Command: Read System Parameter
  • Address: 000A (multiplexer control)
  • Blocks: 01
  • Hit the “Send” button.  The “Response” field should populate, and the “Code” field should read “Read System Parameter: Pass”.

In the example below, the request (in binary mode) is: <02>000A00201201000A0001<A4E2>, and the response was <02>00071201000101<AAF3>.  The last two digits indicate that the antenna port is currently set to port 1, and that “Write System Parameter” was successful.
