Overview of the ZT‐255x Configurations Options/Parameters
1.
“Pan ID” is the group identity of a ZigBee network, and must be the same if
they are in the same ZigBee network.
3
Introduction of configurations
(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.

Frequency(MHz) 2405
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, t
he RF Channel 4, 9,
E and F of ZigBee are recommended in this case.

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.

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.

[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.
(Note: 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.

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.

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.

Data is sent to all of ZigBee slaves

ZT‐2550 Unicast
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 recei ves 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.

Testing Communications
Method (1)
Connect both the ZT‐2550 and ZT‐2551 to the Host PC via the RS‐232 port.
You may need to use two serial port tools to simulate the data transmission.

If you have any difficulties using your ZT‐255x series module, please send
a description of the problem to
[email protected]
Include the following items in your email:
•A description to the communication protocol for more information.
•A copy of the configuration file for the ZT‐255x module. This file can be
obtained using the procedure outlined below and should be attached to your email.
a.
Set the DIP switch of the ZT‐255x device to the [ZBSET] position then
reboot the device. Launch the ZT Configuration Utility and select [Save
Log] icon to save the configuration of the ZT‐255x as a file.
b.
