1. OVERVIEW
This card provides an easy way of interfacing your inputs and outputs from your
Ethernet Smooth Stepper third port. It provides terminals for the connections
and conditions the signals for use in CNC applications. You can connect other
boards using the standard RJ45 cables.
2. FEATURES
•RJ45 connectors for all I/Os. Only standard networks cables needed to make
all the connections.
•Common selection for inputs. Includes jumpers to select the best input
configuration for your application.
•Opt -isolated inputs.
•Output pins 1, 14, 16, 17.
•Input pins 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 15.
•Input and output pins with close by ground or +5vdc connections

6.3 Select JUMPER COM for the inputs
Set the Jumper to COM = +5VDC, GND or 12VDC / 24VDC to determine the common for
the input signals to be used.
COM = 5V
COM = GND with 5V
COM = GND with 12VDC / 24VDC
