4.2 Serial Ports
The serial ports on the AG-EPC-32 allow communication with external devices to the control, PC-type, PLC
and other.
➢SER1: 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 AG-EPC-32 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

4.3 CAN BUS Port
The port CAN BUS allows the communication of the card AG-EPC-32 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 AG-EPC-32 board is configured as MASTER, insert always the TERMINATOR JUMPER
If the AG-EPC-32 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 AG-EPC-32 Canopen system , is 10.
It is a total for PDO Rx and PDO Tx ex:
7 → PDO Tx
3 → PDO Rx
WARNING
USE THE CABLE FOR CANOPEN COMMUNICATION

4.6 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.

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).

5Programming
5.1 Button Boot – LOG-MEM
When the AG-EPC-32 is in running mode (VTB Application in execution) and are presents some messages in
the LOG-MEM (LED RED - ER), if this Button is pressed for 2 Second, the LOG-MEM memory will be cleared.
5.2 Boot Safe Mode (only for Ethernet)
Generally for upload the VTB Application by ETHERNET port, is necessary that the current application that run
in AG-EPC-32 isn’t crashed.
Some times, because there are some programming errors, the VTB application in AG-EPC-32 can be crashing
and this does not allow to upload a new application from Ethernet port (in this cases is used the Manual Boot
and SER1 RS232)
NGWARP allows to use the Boot Safe Mode for use the ETHERNET port for upload the VTB Application.
Procedure:
1) Press BOOT and RESET simultaneously
2) Release button RESET only (led L1 will flash quickly)
3) Keep pressed button BOOT for 4 seconds until the led L1 will flash at 1 second frequency
4) Now you can use the NGPROG in ETHERNET for upload the VTB Application
5.3 Manual Boot
The board usually uses an automatic boot.
In case, the automatic boot is not available, it is necessary to proceed in the following way:
1) Run the program NGPROG (if used VTB skip PULSE 2 and 3)
2) Set the COM and the type of card AG-EPC-32
3) Load the application. SREC and press TRANSFER APPLICATION
4) Press the keys simultaneously within 15 seconds RESET AND BOOT on the board
5) Release the RESET button
5.4 Upload VTB application
For upload VTB application, is possible use the following mode:
The board AG-EPC-32 is automatically in BOOT MODE (if is not available, see 5.1) when you use the BUTTON
UPLOAD APPLICATION. The application is automatically RUN when the transfer is finish.
5.5 NGPROG
The application was developed by Promax NGPROG to allow the update software and firmware.
5.5.1 Upload firmware
1) Press button “FIRMWARE MANAGEMENT” on NGProg
2) If you use “UPDATE da File” use the standard windows Browser for find the .SREC file
2) If you use “UPDATE da Server” you must have a internet active connection, NGPROG
search in Promax server the new version of firmware
3) Select the serial port to PC and AG-EPC-32 board type
4) Start the upload firmware
5.5.2 Upload VTB application
1) Select the AG-EPC-32 (or NGM13 if not present) Board
2) Select the COM on PC
3) Selct the .SREC file by button “LOAD”
4) Start the upload by button “Upload Application”
