IntroductiontoZigBee
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.

IntroductiontotheZT‐255xModule
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
addition, 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.
For more information, please refer to the relevant documents for these
devices, which can be found at following link:

SettinguptheZT‐255xmodule
4.1 Introductionofconfigurations
1. “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)
2. “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)
3. “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
Frequency(MHz) 2405 2410 …… 2480
※ In addition, the RF channels 0x04, 0x09, 0x0E and 0x0F are recommended
because they are not covered with the frequency of Wi-Fi.

4. “RF Power” denotes the wireless transmit power value.
Code Note
0x0F Typical Maximum
0x08 Fit the CE/FCC certification
0x00 Typical Minimum
※ The parameter adjustment purely personal behavior, ICP DAS can not
guarantee to pass CE/FCC certification if adjusting this parameter, nor
assume any liability because of the adjustment parameters derived from the
RF Power.
5. “Baud rate & Data Format” values are based on the configuration of the
serial port.
Item Specification
Parity None, Odd, Even, Space and Mark
Data Bit 7, 8

6. 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.

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

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

[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

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.

Data will be sent to a specific ZigBee slave.
The Address of DCON/Modbus command is regarded as

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
