PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module

5.4 Radio Channel Adjustment

The radio channel used by PTM 215ZE can be changed whenever PTM 215ZE is in commis-

sioning mode. Refer to chapter 3 for a summary of the supported radio channels.

In order to change the radio channel, press the selected button contact shortly (< 7s) once

after entry into commissioning mode. This will reset the radio channel used by PTM 215ZE to

channel 11 and enable subsequent channel adjustment.

If PTM 215ZE was already operating on channel 11 (default condition) then the radio channel

will remain unchanged. This ensures that PTM 215ZE will always use channel 11 as starting

point for the radio channel adjustment.

The radio channel can now be incremented by continuing to press the selected button contact

shortly (< 7s). For each such button press, the radio channel is incremented. If channel 26

has been reached, then channel 11 will be used next.

5.4.1 Adjustment examples

Example 1: PTM 215ZE operating on channel 11 (out of the box condition)

In this case, PTM 215ZE would send a commissioning telegram on channel 11 immediately

after detecting the long-short-long sequence.

After that, it would for each additional short button press send commissioning telegrams on

incrementing radio channels starting with channel 11.

This means that the channel sequence would be:

11 (current channel) - 11 – 12 – 13 … 25 – 26 – 11 – 12 and so on

Example 2: PTM 215ZE operating on channel 15

In this case, PTM 215ZE would send a commissioning telegram on channel 15 immediately

after detecting the long-short-long sequence.

After that, it would for each additional button press send commissioning telegrams on incre-

menting radio channels starting with channel 11.

This means that the channel sequence would be:

15 (current channel) - 11 – 12 – 13 … 25 – 26 – 11 – 12 and so on
