4.1 Power
The NGMEVO requires two separate power supplies:
Logical Power, PWR
Digital Outputs Power, J3 e J4
To supply the digital outputs, see the relevant chapter 4.9
As regards the supply of the logic section, this is necessary for normal operation of the card

4.2 Serial Ports
The serial ports on the NGMEVO allow communication with external devices to the control, PC-type, PLC
and other.
SER1-PRG: is normally used both for the download of the programs on the control, both for the
debugging from a PC application. It is also the port to use for updating the firmware
SER2: Can be used for communication with other devices, such as a PLC, inverters or other. CAN BE
CONFIGURED RS485 MODE.
For the electrical signal, the serial ports are in compliance with RS232/RS485.
Use a CABLE WITH SHIELD for serial ports connections
Connect the SHIELD to PIN 5 SER1 or SER2 to NGMEVO ports
Generally the RS232 connection, uses a NULL MODEM cable (pin 2,3,5) CROSSOVER (with inversion on pin
2,3)
Always check the external device that type of connection it accepts
RS232
RS485
Normally the GND pin is not connect

4.3 CAN BUS Port
The port CAN BUS allows the communication of the card NGMEVO with type devices for motors drives, slave
of various kinds, encoders, and more.
Communication takes place via the CAN OPEN protocol, based on its specifications DS401 and DS402 as
regards the objects and the modes supported.
In terms of data exchange, the line complies with DS301.
The port can be configured as master or slave depending on the firmware present.
The port CAN-BUS meets the specifications of ISO 11898-24V.
4.3.1 Connection CAN BUS
Is possible insert the TERMINATOR RESISTOR, inserting the JUMPER above the power connector.
WARNING
If the NGMEVO board is configured as MASTER, insert always the TERMINATOR JUMPER
If the NGMEVO is configured as SLAVE, insert the TERMINATOR JUMPER if the board is the last node in the
CanBus.
In another situations, remove the JUMPER
4.3.2 CanOpen Max PDO Number
Normally the max PDO number managed by NGMEVO Canopen system , is 10.
It is a total for PDO Rx and PDO Tx ex:
7 → PDO Tx
3 → PDO Rx

4.4 Ethernet Port
The Ethernet port, allows the NGMEVO to communicate with other devices, llike PC and others. On data
exchange level, it complies 10 BaseT and 100 BaseT standards.
About protocols, it can be used in many ways:
NGMEVO to PC communication, about on-line assistance. In this case it's used a PROMAX specific
protocol;
PLC and other devices communication, with ModBus TCP/IP protocol;
4.4.1 Connections
The on board connector, complies the RJ45 standard,
It's recommended to use PC with Ethernet ports complies this standard. It's recommended to use cables
length conformed the standard.
The connection cable can be CROSSOVER or NORMAL
The port is automatically adapted to cable type
WARNING
USE THE CABLE FOR ETHERNET COMMUNICATION

4.5 Analog inputs
The analog converter reads an input voltage from 0 to 10V or 4/20 mA with respect to GND.
To get the full scale 12V or 24V, an external resistor must be inserted between the signal and card input. In
any case, the value of the input voltage can exceed the full scale is not more than 0.2 V.
The use of analog input, remove automatically a digital input (see the following table)

The NGMEVO can use an internal input encoder Line Drive.
When this option is enabled, the number of PULSE/DIR channels is TWO.
This encoder input is normally used for HANDWHEEL FUNCTION
It means that the frequency inputs is not to high.

4.10 Digital Outputs
These outputs are optically isolated with respect to GND. In order to function should therefore feed them
separately with a voltage of 24 Vdc. The load is driven by a transistor of the PNP type which when activated
will provide a positive voltage equal to the voltage supply of the outputs.
The outputs have a protection:
REVERSE TENSION
TEMPERATURE
SHORT CIRCUIT
On the card there is a protection diode so you can also directly drive inductive loads. In case of inductive loads
with absorption greater than or equal to 0,5 A or when the cable connection between the load and board
exceeds a length of 3 meters, you should put the protection diode also close to the load (diode type 1N4007
or similar).
