“TT” needs to show up in pairs (“TTTT” in the mask) and is unique to Control Solutions ZB25-T or ZB25-TH sensors.
This mask will parse the thermistor reading and linearize it to a normalized reading in degrees Celsius x 100. Refer to
Appendix A for examples specific to the Control Solutions ZB25 series sensors.
The first byte in the above example is the API frame type code. The next 10 bytes are the 64-bit and 16-bit addresses of
the remote device the packet was received from. Do not force matching on these bytes. These are automatically checked
against the addresses found in the device list. You only need to select a device by name.
The example above says we must see 0x92 in the first byte of the API frame, and values 0x01 and 0x0E where shown.
We are going to extract data from the positions indicted by XXXX. In this case, we are extracting the current (amps)
level from a Digi International Smart Plug. Visit the BB2-7040 product page at www.csimn.com

documentation.
6.2 ZigBee Client Write Maps
A note about "writing" ZigBee devices: ZigBee is optimized for low power battery operated sensors that sleep most of
the time. This means that any attempt to "write" really means queuing up a message for some time later. Each write map
includes a timeout. The meaning of timeout is simply that the local BACnet object whose data is supposed to be
transmitted will have its reliability code set showing the timeout, and the BB2-7040 will retry. The timeout should
always be set longer than the sleep period of the remote ZigBee device intended to receive this data.
Map number simply tells you where you're at on the list of object maps. Click "next" and "prev" to scroll through the list.
To advance directly to a specific map, enter the desired number in the "Showing" box, then click Update.
Maps entered on this page only write data to remote devices. Go to the Client Read Map to read data from those devices.
The full parameter set is different for read versus write.
An abbreviated version of a list of maps is shown on this page. Any of the parameters shown may be changed here and
registered by clicking the Update button. To view and/or modify the complete set of parameters, click on the map
number in the left most column.
For each remote object to be written, select the device to write and provide a data formatting mask. Select the local
object from which data will be written to the remote device. The names in the device list are defined in the Devices page.
Details about the data format mask may be found on the extended map view page by clicking the map number in the left
most column.
