PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

4.4.1.3 Device ID other than 0x07

It is possible to configure PTM 535BZ via NFC to use one of the alternative Device ID listed

in Table 6 instead of the default Device ID 0x07.

The ZGP specification [3] defines the minimum set of commands that must be supported for

each Device ID but leaves it up to the user to define which input actions trigger these com-

mands. The specification also allows the user to define additional commands for the remain-

ing input actions. The receiver is informed about the set of commands used by PTM 535BZ

by means of the command list which is part of the commissioning telegram as described in

Chapter 4.4.2.3.

PTM 535BZ therefore uses a command table with eight entries corresponding to each of the

eight possible combinations of ECO 200 action (Press or Release), INPUT1 and INPUT2 status

(Connected or Not Connected) to determine which ZGP command will be sent upon the cor-

responding input status when PTM 535BZ is configured to use a DEVICE ID other than 0x07.

It is NFC configurable which direction of ECO 200 movement is considered as Press action

and which is considered as Release action. The default behaviour is that a Press action is a

move of the ECO 200 spring away from the PCB and that a Release action is a move of the

ECO 200 spring towards the PCB.

Table 8 below shows the structure of this command table together with the default ZGP

command for each of the eight possible combinations.

Table Index INPUT2 Status INPUT1 Status ECO 200 Action Default Command

ZGP_COMMAND_0 Not connected Not connected Press action 0x22

ZGP_COMMAND_1 Not connected Not connected Release action 0x23

ZGP_COMMAND_2 Not connected Connected Press action 0x12

ZGP_COMMAND_3 Not connected Connected Release action 0x13

ZGP_COMMAND_4 Connected Not connected Press action 0x14

ZGP_COMMAND_5 Connected Not connected Release action 0x15

ZGP_COMMAND_6 Connected Connected Press action 0x16

ZGP_COMMAND_7 Connected Connected Release action 0x17

Table 8 – ZGP command table for Device ID other than 0x07

The default ZGP commands in the command table shown above have been defined to meet

the requirements for DEVICE ID = 0x02 (ON / OFF Switch) and provide backwards compati-

bility to PTM 535Z.

The command table can be modified by the user according to application and specification

requirements by writing the corresponding ZGP command via the NFC interface as described

in Chapter 5.6.13. PTM 535BZ will accept (and transmit) one-byte values between 0x00 and

0xFE. PTM 535BZ will not perform compliance checking on the defined commands.

If an entry in the table is set to 0xFF (which is not a valid ZGP command for a ZGP device)

then no data telegram will be transmitted for the corresponding input status. This can be

useful if for instance a push button should only transmit data telegrams upon press.
