Note: USB connection is not galvanically isolated 7.2. Using Ethernet - direct connection between PoKeys57CNCpro4x25 and computer Network firewalls must allow all traffic on TCP/UDP port 20055 between PoKeys57CNCpro4x25 device and PoKeys-related software running on a computer. Step 0 (prerequisite): install PoKeys setup package (version 4.7.9 or newer)
Page 21: Using Ethernet - Pokeys57Cncpro4X25 Connected To A Network With Dhcp Server
7.1. Using USB and Ethernet PoKeys57CNCpro4x25 device can be connected to the computer by using both the USB and Ethernet connection. In this case, applications will detect two instances of PoKeys57CNCpro4x25 devices and USB connection will be selected by default by third-party applications.
Page 22: Pokeys Configuration Options
Note: if PoPendant is connected to the PoKeys57CNCpro4x25 over CAN, PoKeys pins 3-6, 9-11 and 15- 16 will represent the state of the PoPendant signals (axis and step selection switches), as in PoKeys57CNC.
Page 23: Encoders
– green for the activated (HIGH state) and white for the unactivated (LOW state). Not all squares that are rendered in this display represent an actual pin on the PoKeys57CNCpro4x25. To change the digital output state, first enable ‘Enable output control’ option, then either left or right click with mouse on the square representing the digital output to activate or deactivate this output.
Page 24 PoKeys57CNCpro4x25 user manual v1.00 Fast encoders are not intended to be used natively on PoKeys57CNCpro4x25 because of the lack of extenally available digital IO pins. Figure 3: Encoder settings in PoKeys application www.poscope.com...
Page 25 Fast encoders are disabled so only ultra fast encoder is relevant. At the bottom of the window, there is a command button that can be used to reset the encoders’ values. Note: if PoPendant is connected to the PoKeys57CNCpro4x25 over CAN, encoder 1 will represent the encoder on the PoPendant itself.
Page 26: Pulse Engine
8.3. Pulse engine PoKeys57CNCpro4x25 is a hybrid device between a PoKeys57CNC device and a set of PoStep25-256 stepper motor drivers. As such, it contains an external pulse generator on-board, which is driving 4 stepper motor drivers by STEP/DIR signals with maximum pulse frequency of 125 kHz.
Page 27: Pulse Engine Status/Control Dialog Parts
Enable backlash compensation: check this option to enable the backlash compensation in PoKeys device. 2. Pulse generator options: PoKeys57CNCpro4x25 contains an external pulse generator on- board, thus external pulse generator option with ‘Extended IO’ must be selected. 4 axes are enabled by default.
