The TDM time sequence is set in the Tag Protocol page as part of the Multi-Protocol Acquisition Sequence

(Frame Sequence), see Multi-protocol tag acquisition sequence building, page 63.

Frequency Selection

Select the Tag Protocols page and select a specific protocol icon to show the operating frequency settings for

that protocol.

Note1: There must be at least a 2.5 MHz frequency separation between adjacent antennas, either in a

single or multi-reader environment.

Note2: The FCC allowed frequencies are RF Module model and protocol specific. See Appendix B for

details.

Note3: Typically, the channel operating frequency selected will be the same for all FDM protocols

Note4: The TDM and Title21 protocol operating frequencies are fixed and cannot be changed

Note5: If the configuration alignment icon is shown in the banner , you only need to change frequency

settings on the Primary side of the reader. Any changes are then automatically applied on the Secondary

side.

Result: The following screen is shown as an example (6C protocol in a 5 channel configuration).

RF Attenuation

The transmit power is adjustable individually by protocol and channel by controlling the Tx (transmit)

attenuation setting. Similarly the receive sensitivity can be adjusted individually by protocol and channel by

controlling the Rx (receive) attenuation.

Select the Tag Protocols page, then one of the enabled protocols in the frame sequence. Then adjust the

desired Tx and Rx attenuation for each channel.

Note: If the configuration alignment icon is shown in the banner , any attenuation change made on the

Primary is also set automatically on the Secondary side.
