Frame Sequence Synchronization rules

When building a multi-protocol tag acquisition sequence (Frame Sequence) where readers are required to be

synchronized, the following rules must be followed to avoid errors or warnings.

• Only one sync block may be used when only 1 or 2 protocol sequences are enabled in the multi-

protocol sequence.

• If 2 or more sync blocks are used in the multi-protocol acquisition sequence, one of the blocks must

be enabled to Skip-on-Sync.

• With multiple sync blocks in an Frame Sequence, they should each be different (e.g. Sync_1, Sync_2)

to ensure correct alignment.

• The sequences on the readers must be the same or at least have the same time length(s) between

sync block(s). Dummy frames may be used to achieve this if the sequences are different.

Example building a Frame Sequence

Two examples are provided below, one using a single protocol and no sync, while the other is a multi-protocol

sequence with sync.

Note 1: To use the examples sequences over the air it is also necessary to set channels to Active or Guard

on the Channel page, and to set appropriate attenuations for each channel.

Note 2 : To support read/write operation it is necessary to configure the TDM programming configuration,

see Programming tags, page 61.

Connect a service laptop to the reader and via browser connect to the reader web interface.

Example 1: Set up a TDM (Read/Write) protocol, eight (8) lane plaza, not synced to another Reader.

1. Select the Channels page. Set the "Number of channels" to 8. This automatically sets a 8 channel TDM

scan.

2. Select the Tag Protocol page. Select and delete via the icon, all protocols except TDM. You should

have the resulting frame sequence as follows:
