1 Introduction
1.1 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 required in order 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 transmission rate of 250 kbit/s, best suited for
periodic or intermittent transmission of data, or for 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.

1.2 Introduction to the ZT-2000 I/O Series
The ZT-2000 I/O series of devices are small wireless ZigBee I/O modules based
on the IEEE802.15.4 standard that allow data acquisition and control via personal area
ZigBee networks. See Section 3.1 for more detailed information.
The ZT-2000 I/O series is a wireless data acquisition-based client/server system.
Accordingly, a Net Server for the ZigBee (ZT-2570/ZT-2550) is essential in such
systems. For more information regarding any configuration issues related to the ZigBee
Coordinator, please refer to the “ZT-25XX ZigBee Converter Quick Start” document,
which can be found at:

3 Setting up the ZT-2000 I/O Device
3.1 Introduction to the Configuration
Parameters
A. The “ZB PID” parameter is the group identity for a ZigBee network, and must
be the same for all devices in the same ZigBee network.
B. The “Node ID” parameter is the individual identity of the specific ZigBee
module, and must be unique for each device connected to the same ZigBee
network.
C. The “ZB Channel” parameter indicates the radio frequency channel, and must
be set to the same value as other modules on the same ZigBee network.
ZB Channel

※ ZB channels 0x04, 0x09, 0x0E or 0x0F are recommended because they do not overlap with
the Wi-Fi frequency band.
D. Protocol/Application Mode:
When implementing custom programs based on different protocols, the following
application mode(s) are recommended in order to ensure optimal performance.

3.3 Starting the ZT-2000 I/O Device
As the ZigBee network is controlled by the ZigBee Coordinator, the ZT-2550/ZT-2570
(ZigBee Coordinator) must be configured first. Refer to the documents section below
for full details of how to configure these devices.
Once configuration of the ZigBee Coordinator has been completed, set the “ZB PID”
and “ZB Channel” values for the ZT-2000 I/O device to the same values as the
network, and then reboot the device. The module will automatically start to function on
the ZigBee network using the default protocol.
※ Documents
Helpful documentation related to the ZT-2550 and ZT-2570 can be found at:
http://ftp.icpdas.com.tw/pub/cd/usbcd/napdos/zigbee/zt_series/document/zt-255x/
http://ftp.icpdas.com.tw/pub/cd/usbcd/napdos/zigbee/zt_series/document/zt-257x/
※ Configuration Utility
A utility that can be used to configure the ZT-2000 I/O device Coordinator is available
for download from:
http://ftp.icpdas.com.tw/pub/cd/usbcd/napdos/zigbee/zt_series/utility/
3.4 Communications Testing
Once the ZT-2000 I/O device has joined the ZigBee network, the signal quality can be
confirmed by monitoring the status of the ZigBee Net LED indicators. If the LED
indicator shows a steady light, communication with the ZT-2000 I/O device has been
successfully established for data acquisition and control.
ICP DAS provides the “DCON Utility” which can be used to simulate DCON/Modbus
communication. This software can also be used to verify the device settings and the
ZigBee I/O functions.
The DCON Utility can be downloaded from:
http://ftp.icpdas.com/pub/cd/8000cd/napdos/driver/dcon_utility/

5 Calibration
Warning
Performing calibration is not recommended until the process is fully understood.
The calibration procedure is as follows:
1. Warm up the module for at least 30 minutes.
2. Set the Type Code to the type you wish to calibrate. Refer to Section 4 and Section
6.2.13 for details.
3. Enable calibration. Refer to Section 6.2.31 for details.
4. Apply the zero calibration voltage/current.
5. Send the zero calibration command. Refer to Section 6.2.7 for details.
6. Apply the span calibration voltage/current.
7. Send the span calibration command. Refer to Section 6.2.6 for details.
8. Repeat steps 3 to 7 three times.
Notes
1. The calibration voltage/current source should be connected to channel 0.
2. Calibration voltages and currents are shown below.
3. Switch to DCON protocol mode before calibrating the module. Refer to Section 3.2
for details of how to switch protocols.

6 The DCON/Modbus RTU Command Sets
6.1 Communicating with the ZT-2000 I/O Device
ICP DAS ZT-2000 I/O devices can be operated using either the DCON or the Modbus
RTU protocol, which can be selected by adjusting the position of DIP switch 2 to OFF
(DCON) or ON (Modbus RTU) and then rebooting the ZT-2000 I/O device to user the
new protocol.
6.2 The DCON Protocol Command Set
All ZT-2000 I/O series devices are controlled via wireless broadcast commands, so
each device must have a unique address that is saved in the EEPROM of the device.
Consequently, all command and response formats contain the address of the
destination module. When an I/O device receives a command, it will determine whether
or not to respond based on the address contained in the command. However, there are
two exceptions to this, the #** and ~** commands.

6.2.1 Checksum
Calculating the Checksum:
Sum the ASCII codes of all the characters contained in the command in addition to the
‘CR’ terminator. The Checksum is the sum value expressed in Hexadecimal format.
Example: Command “$012(CR)”
Sum = ‘$’ + ‘0’ + ‘1’ + ‘2’ = 24h + 30h + 31h + 32h = B7h
Checksum = “B7”
DCON Command with Checksum =“$012B7(CR)”
Example: Response “!01200600(CR)”
Sum = ‘!’ + ‘0’ + ‘1’ + ‘2’ + ‘0’ + ‘0’ + ‘6’ + ‘0’ + ‘0’
= 21h+30h+31h+32h+30h+30h+36h+30h+30h
= 1AAh
Checksum = “AA”
DCON Response with Checksum = “!01200600AA(CR)”
※ Note: The Checksum is the sum value expressed in capital letters.
