2.3 Zlinx Xtreme I/O Modes of Operation
Zlinx Xtreme I/O systems can operate in Peer-to-Peer or Modbus Slave RTU modes. 900 MHz I/O Modules can be configured
as repeaters to extend the radio coverage distance.
2.3.1 Peer-to-Peer I/O Mode
Peer-to-Peer configuration of IO modules is used in wire replacement applications for analog/digital IOs where cabling is not
possible or it is very expensive. Typical examples include remote monitoring and control applications in clean rooms, buildings
across parking lots or highways, remote water or fuel tank level monitoring, remote pump station control, etc.
In Peer-to-Peer mode, two Zlinx I/O modules of same type can be configured to provide wire replacement functionality. Input
count of one module must match the output count of the other module for both digital and analog types. For example, a pair of
2 analog input, 2 analog output, 2 digital input and 2 digital output I/O modules or a pair of 4 digital input and 4 digital output
modules can be configured in peer-to-peer mode. A pair of the following I/O modules is suitable for Peer-to-Peer configuration:
- ZXT9-IO-222R2
- ZXT24-IO-222R2
In this mode one Module is configured as a Master and the other as a Slave. It does not matter which end of the link is the
Master and which is the Slave. Analog and Digital Input signals connected to one module are mapped to the corresponding
analog and digital outputs on the other module and vice versa. Peer-to-Peer mode configuration can be established between
outdoor rated Zlinx Xtreme IOs and indoor rated Zlinx Gem II IOs.
Note: However, -MR versions of indoor rated Zlinx Gen II I/O modules are not compatible with Zlinx Xtreme modules.
Figure 1-2 Peer-to-Peer Mode

Product Introduction
Manual Documentation Number: ZXTx-IO-x-2310m 7
2.3.2 Modbus I/O Mode
In Modbus mode, the Zlinx Xtreme I/O modules shall be configured as Modbus Slaves and can be controlled and monitored by
a Modbus RTU Master (such as a PLC, SCADA, HMI, etc). A serial radio modem acts as a data pipe & has to be connected to
the Modbus master through its serial port. Up to 247 wireless I/O modules can be remotely monitored and controlled by the
Modbus master. The I/O signals appear in the Modbus register map resident in the I/O module memory that can be accessed
by the master through the radio modem. Refer to Appendix – D for information about the Modbus register mapping.
Figure 2-2 Modbus I/O Mode
In Modbus I/O mode, up to 247 Zlinx I/O modules can be connected to a Modbus RTU master through a Radio Modem.
Modules of both Zlinx Xtreme (outdoor) and Zlinx Gen II (indoor) types can be mixed and matched as long as their frequency
rating is the same.
2.3.3 Repeater Mode
Figure 2-3 I/O Module as a Repeater
When a Zlinx Xtreme I/O Module is configured as a repeater, it relays data from a Modbus modem or an I/O Module and
extends the range of communication. In a Peer-to-Peer System, a repeater unit can be placed between the Master and the
Slave IO modules.
Only 900 MHz radios support the repeater functionality.
NOTE: Placing a repeater in a system will introduce an additional delay of 4ms. Each
repeater introduced in a system will cut the data bandwidth to half.

2.4 I/O Types and Characteristics
The analog inputs, analog outputs and digital inputs are not isolated. They share the same common within the module. Digital
outputs are isolated through relay contacts.
2.4.1 Digital / Pulse Inputs
Digital Inputs can detect the status of discrete control devices, contact closures, transistor switches or on/off DC voltage
signals (low or high logic levels). Voltages below 1 VDC are interpreted as a low state. Voltages above 1 VDC up to 48 VDC
are interpreted as a high state.
Each digital Input is selectable between NPN (sinking) and PNP (sourcing) types. The digital Input terminals can accept
voltages in the range 0-48VDC.
The digital inputs can also be used as a pulse/frequency input in Modbus mode only. The maximum pulse frequency is 20
KHz.
2.4.2 Digital Outputs
Digital Outputs send on/off signals (low or high logic levels) to drive external devices such as indicators, relay coils or the
inputs of other equipment such as PLC’s, SCADA, etc. Digital Outputs in Zlinx Xtreme I/O modules have a Form C Relay
(common, normally open and normally closed) rated at 4A and 250VAC.
2.4.3 Analog Inputs
Each analog input can be individually configured as voltage or current types. Following selections are available:
a) 0-10 Vdc
b) 0-5 Vdc
c) 0-20 mA
d) 4-20 mA
The data is automatically scaled as a 16 bit register (0-65,535) for full scale in the Modbus register. To see how to calculate
corresponding values in Modbus, refer to section Appendix F.
2.4.4 Analog Outputs
Each analog output can be individually configured as voltage or current types. Following selections are available:
a) 0-10 Vdc
b) 0-5 Vdc
c) 0-20 mA
d) 4-20 mA
The data is automatically scaled as a 12 bit register (0-4,096) for full scale in the Modbus register. To see how to calculate
corresponding values in Modbus, refer to section Appendix F.

3.1 Recommended Practice Before Installation
Before installing a new system, it is recommended to bench test the complete system and make sure the modules function
satisfactorily. Refer to appropriate sections for your setup in Chapter 8 for reference.
In actual installations, poor communications can be caused by:
Incorrectly installed antennas.
Radio interference.
Obstructions in the radio path.
Bad weather
Signal out of range.
If the radio path is a problem, higher gain antennas would help improve the range.
3.2 RF Site Considerations
When installing any radio equipment it is important to give careful consideration to the installation location and the surrounding
area. Radio transmission and reception is affected by absorption, reflection and refraction of the radio signals. These factors
are determined by the distance between the transmitting and receiving antennas, the type, position and amount of
obstructions, antenna heights, frequency band and RF power used, and other factors.
There are several ways to optimize the RF environment to ensure satisfactory performance. A partial list of these follows:
Select the Zlinx Xtreme I/O radio option that provides sufficient power for your application. Lower frequencies travel
farther and are less affected by absorption in materials. Higher power levels generally provide greater penetration
through objects.
Select installation locations that come as close as possible to providing Line Of Sight access between the antennas.
Avoid installation locations where metal objects may block, reflect, refract or cause multipathing of radio frequencies.
In some cases reflections may enhance reception but in others it can cause problems.
Select installation locations to increase antenna heights.
Consider signal loss across antenna cables and connectors. User larger cables for low signal loss.
Select equipment enclosures made of materials that minimize RF attenuation.
Avoid locations with other radio equipment that may cause interference.
In some cases alternate types of antennas (more directional) or remote antenna mounting (outside of enclosures or
at a higher elevation) may be required.
As necessary, site survey should be carried out. Sometimes small changes in location can make a significant improvement to
coverage. For RF information see Appendix G.

3.4 Mounting Options
The Zlinx Xtreme I/O module can be panel or machine mounted. The module can be mounted with or without the optional
mounting ears.
3.4.1 Without the mounting ears
The Zlinx Xtreme can be mounted on a back panel or a machine by removing the top lid. The top lid is removed by unscrewing
the 4 corner screws. The module can be mounted using the supplied screws and nuts through the corner holes. Once
secured, fasten the top cover.
3.4.2 With Mounting ears
4 optional mounting ears and screws are supplied as accessories. The ears can be attached to the Zlinx Xtreme by removing
the top cover and securing through the corner holes. The module then can be mounted on the panel by marking the position of
the holes on the back panel. Fig 3-2 shows the mounting scheme with ears.

3.5 Cabling Options
The Zlinx Xtreme module has two holes of 0.875” diameter for cable installation. Cable gland or conduit mounting is possible.
A cable gland and conduit hub are included as accessories. Unused hole must be plugged by the supplied membrane gland in
order to maintain IP67 rating.
3.5.1 Cable Glands
A Cable Gland is used to maintain the water tight rating while allowing a cable to enter the enclosure. The assembly consists
of black molded nylon body, hex nut, cable nut and a rubber gasket and cable seal.
Figure 3-3 IP67 Cable Gland
Follow the steps below to install the cable gland:
1. Insert the Non-tapered end of the Body (D) through the conduit knock-out on the I/O module enclosure.
2. Place the Gasket around the body on the outside of the enclosure.
3. Thread the Hex Nut onto the Body from the inside of the enclosure.
4. Insert the cable through the Cable gland into the enclosure. Ensure you leave enough slack in the cable to reach the
terminal blocks.
5. Place the Cable Nut onto the cable being careful to position the threaded side so that it can be attached to the Cable Body.
6. Tighten the Cable Nut. This will cause the tapered end of the Cable Body to compress, ensuring a water-tight seal.
