Introduction to ZigBee
ZigBee is a specification for a suite of high-level communication protocols
using small, low-power digital radios based on the IEEE 802.15.4 standard for
personal area networks. ZigBee devices are often used in mesh network form to
transmit data over longer distances, passing data through intermediate devices
to reach more distant ones. This allows ZigBee networks to be formed ad-hoc,
with no centralized control or high-power transmitter/receiver able to reach
all of the devices. Any ZigBee device can be tasked with running the network.
ZigBee is targeted at applications that require a low data rate, long battery
life, and secure networking. ZigBee has a defined rate of 250 kbit/s, best
suited for periodic or intermittent data or a single signal transmission from
a sensor or input device. Applications include wireless light switches,
electrical meters with in-home-displays, traffic management systems, and
other consumer and industrial equipment that requires short-range wireless
transfer of data at relatively low rates. The technology defined by the
ZigBee specification is intended to be simpler and less expensive than other
WPANs.
Introduction to the ZT‐255x Module
The Basis of ZT-255x Series Product
The ZT-2550 and ZT-2551 series modules are small-sized wireless ZigBee
converters based on the IEEE802.15.4 standard that allow RS-232, RS-485
interface to be converted to a personal area ZigBee network. The typical
transmission of ICP DAS ZT series ZigBee products is 700 meters (LOS, line of
sight), with a transmission frequency range of between 2.405 GHz and 2.48
GHz, separated into 5 MHz sectors, providing 16 channels and 16384 PAN IDs.
ZT-2000 series is not only a long distance wireless converter but also can
act a ZigBee router to extend the transmission range and improve the quality
of wireless signal.
ZT-2000 series products are specification for a suite of high level
communication protocols using small, low-power digital radios module, which
are fitted the ZigBee 2007 (ZigBee Pro) of ZigBee Alliance. In the ZigBee
network, it is only allowed one ZigBee Host and called “ZigBee Coordinator”,
ZT-2550 series products, are used to initialize and manager the routing. In
ddition, One ZigBee network are able to manager 255 ZigBee router and
responsible for receiving or bypassing data from parent or child node.
The Benefits of ZT-255x Series Product A Windows compatible GUI configuration
utility is available. The utility allows users to set different configurations
based on the type of application, together with several of required ZigBee
variables such as Pan ID. The friendly user interface is also helping user be
familiar with ZT-2000 series.

Setting up the ZT‐255x module
4.1 Introduction of configurations
-
“Pan ID” is the group identity of a ZigBee network, and must be the same if they are in the same ZigBee network. (Valid values range from 0x0000 to 0x3FFF)
-
“Node ID” is the identity of the ZigBee module.
The identity number must be unique if it is in the same ZigBee network as other ZigBee module. (Valid values range from 0x0001 to 0xFFF7 for a ZigBee Router, but is fixed to 0x0000 for a ZigBee Coordinator) -
“RF Channel” indicates the radio frequency channel, and must be set to the same channel if the module is in the same ZigBee network as other ZigBee modules.
Channel | 0x00 | 0x01 | …… | 0x0F |
---|
Use application tools or analyzers to detect the wireless signal, chose a RF
Channel which has not been occupied. E.g. Wifi Analyzer
As below the screenshot shown, there were several WLANs over the channel 1, 6
and 11. Referring to the channel table of WiFi and ZigBee, the channels of
ZigBee 4, 9, E and F are not overlap with WLAN. So, the RF Channel 4, 9, E
and F of ZigBee are recommended in this case.
- RF Channel Table to ZigBee(802.15.4) and WLAN(IEEE 802.11b/IEEE 802.11g)
“RF Power” denotes the wireless transmit power value.

Communication
Speed (The Interval Time of Sending Broadcast Frame):
The data payload of ZT-2000 series modules is 79 bytes. Once the data is more
than 79 bytes, it will be divided into several packets. This parameter is used
to decide the interval time of sending broadcast frame in order to prevent
the network crashes. Please fill in the number of ZT-2000 slaves nearby the
ZigBee Coordinator.
Example:
Application Mode can be changed and used for certain specific purpose.
The above schematic diagram is showing what the difference of using different
application modes.
a. Transparent Mode is the default application mode, and always transmits data
to the remote device via broadcasting. Unless there are specific purposes, the
application mode can be retained as default.
The mode always bypasses data to remote side via broadcasting. If there is no
particular purpose, user only keeps this application mode.
Module | Frame Type | Note |
---|---|---|
ZT-2550 | Broadcast | Data will be sent to all ZigBee slaves |
ZT-2551 | Unicast | Data will only be sent to the coordinator |
[Eg1] When ZT-2550 ZigBee Host sends “DATA_01” via broadcasting frame, →
Both of the ZigBee slave 0x0001 and 0x0002 will receive the DATA_01.
※Broadcasting type frame, data will be sent to every ZigBee slaves in the same
ZigBee network
[Eg2] When the ZigBee slave 0x0001 sends “DATA_02” via unicast frame, →
Only ZT-2550 receives DATA_02.
※Unicast type frame, data will only be sent to the ZigBee host
※ There is an “Advanced Settings” for some specific user, please refer the section 7.3 ”Non-addressable Device Communication” to user manual for more information.
b. Addressable Mode is an advanced application mode and it is used to send data to specific ZigBee nodes. It is not only used to transmit data to specific ZigBee slaves from host but also transmit data between ZigBee slaves. A 5-byte ASCII code should be added as an index before the data.
Module | Frame Type | Note |
---|
ZT-2550
ZT-2551| Unicast| Data will be sent to a specific ZigBee slave.
Format: “:AAAA” + Data
[Eg1] When ZT-2550 ZigBee Host sends “:0001DATA_01” via unicast frame,
→Only the ZigBee Slave 0x0001 receives DATA_01.
※Unicast type frame, data will be only sent to the specific ZigBee node
[Eg2] When ZigBee slave 0x0001 sends “:0002DATA_02” via unicast frame
→Only the ZigBee Slave 0x0002 receives DATA_02.
※Unicast type frame, data will be only sent to the specific ZigBee node
※ There is an “Advanced Settings” for some specific user, please refer the section 7.3 ”Non-addressable Device Communication” to user manual for more information.
c. Gateway Mode is an advanced application mode and it is used to convert the Modbus protocol. But there is only RS-232 and RS-485 interface supported in the ZT-255x device, so the data is always regarded as Modbus RTU format transmission.
Module | Frame Type | Note |
---|---|---|
ZT-2550 | Broadcast | |
(Default) | Data is sent to all of ZigBee slaves |
Unicast
(Advanced)| Data will be sent to a specific ZigBee slave.
The Address of DCON/Modbus command is regarded as
destination ZigBee address
ZT-2551| Unicast| Data only be sent to coordinator
[Eg1] When ZT-2550/ZT-2570 receives data “MRTU_CMD_01” from serial port,
→ZT-2551 will output the data “MRTU_CMD_01” to serial port directly.
[Eg2] When ZT-2570 receives data “MTCP_CMD_02” from Ethernet, →ZT-2551 will
convert protocol then output “MRTU_CMD_01” to serial port.
[Eg3] When ZT-2551 transmits the acknowledgement “MRTU_ACK_03”,
→ZT-2550/ZT-2570 will response the acknowledgement “MRTU_ACK_03” to serial
port directly.
→ZT-2570 will convert protocol then output “MTCP_CMD_01” to Ethernet.
※Unicast type frame, data will only be sent to the ZigBee host
※ There is an “Advanced Settings” to the Gateway Mode for some specific user, please refer the section 7.2 “DCON/Modbus Device Communication” for more information.

7.2 DCON/MODBUS Module Communication
ZigBee is defined as a low-power and low data rate wireless transmission protocol. In order to prevent excessive transmission loading to the ZigBee network, there is an advanced setting to the Gateway Mode to set the wireless frame type, which is used to select either the Broadcast Frame or Unicast Frame to transmit data.
Once the Unicast Frame is selected, the Address of DCON or Modbus instructions will be regarded as the destination address to the ZigBee. So, the DCON/Modbus devices should be connected to corresponding address of ZigBee module.
For some applications, there are several DCON or Modbus devices should be connected to the same ZT-2551 modules.
Although the addresses of these additional DCON and Modbus devices are not corresponding to the relative ZigBee module, but there is an Address Mapping function supported for redirection to the correct destination address of ZigBee module. User only fills in the relationship of address mapping for redirection via the ZT-2000 Configuration Utility.
7.3 Non‐addressable Device Communication
In some applications, there are some devices can not be addressable and they
even take the initiative to reply data. Once these non-addressable devices
send data to the user’s controller via ZigBee, the user program can not
identify which device sends this data.
For example, there are several barcode readers and RS-232 device connected to
the ZT-2551. Once these devices are triggered to reply data, the controller
will not be able to identify which end device sends the data.
In order to provide a solution for the similar application using non-address device, there is an advanced setting to the Transparent Mode and Addressable Mode to show the Node ID of the remote ZigBee device which is connected to the userʼs end-device.
When the advanced function is enabled, the Node ID will be added in the “:AAAA” format in front of the original data and then be output once receiving remote data.
