INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life,
adequate ventilation must be provided. Avoid positioning ducting or other objects that obstruct the ventilation slots.
Avoid mounting modules over heat-generating equipment. Installation in the bottom part of the electrical panel is
recommended.

Insertion in the DIN rail
As shown in gure:
1. Insert the IDC10 rear connector of the module on a
free slot of the DIN rail (the insertion is univocal since
the connectors are polarized).
2. To secure the module to the DIN rail, tighten the two
hooks on the sides of the IDC10 rear connector.

The module is designed to exchange data according to the modes dened by the MODBUS protocol. It has a micro
USB connector on the front panel and can be congured using applications and/or software programs.
The USB serial port uses the following communication parameters: 115200,8,N,1
The USB communication port responds exactly like the serial ports, with the exception of the communication
parameters.

Power supply
Terminals 2 and 3 can be used to provide the module with power supply as an
alternative to the connection using the Z-PC-DINx bus.
The power supply voltage must remain in the range of either 19 and 40V Vdc (any
polarity), or 19 and 28V Vac.
The upper limits must not be exceeded as this can seriously damage the
module.
If the power supply source is not protected against overload, a safety fuse with a 1 A
max permissible value must be installed in the power supply line.
Serial port 2: RS485 SW2 = OFF
Z- KEY WIFI has a serial port that can be set with the SW2 switch.
If switch SW2 is in the OFF position, the RS485 COM 2 port is available at terminals
10-11-12. The illustration shows how to complete connections.
N.B.: the indication of the RS485 connection polarity is not standardised and in some
devices may be inverted.

COMMUNICATION PORT IDENTIFICATION
RJ45 Ethernet port (on front)
Z-KEY-wi has an Ethernet 10/100 port with RJ45 connector on
the module front.
Micro USB port
Z-KEY-wi has a USB connector that can be used as a
conguration port via the Easy Setup software.
Micro SD card slot
Z-KEY-WIFI has a micro SD card slot on the side of the case.
To insert the SD card in the corresponding slot, make sure the
metal contacts are facing right (as shown in the side gure).
The SD card can be of any capacity.
To activate the rst conguration Access Point function, follow the following steps:
1. Press the side button of the Z-KEY-WIFI;
2. Keeping the button pressed, power the instrument;
3. Release the button after 5 seconds.
Through this procedure, the device switches to rst conguration AP mode without password to enter the
parameters of the WIFI. The AP led will ash.
ACCESS POINT: FIRST CONFIGURATION
OPERATION IN ACCESS POINT MODE
In this mode, a device can function as an Access Point and accept the connection of up to 6 station devices
without the aid of an external Access Point.
This conguration can be activated from the web server.
OPERATION IN STATION MODE
In this mode, the device can connect to an existing Access Point. This function can be activated from the web
server.
