Description

PoNET kbd48CNC v2 is a new upgraded version of the PoNET kbd48CNC keyboard, an excellently machined extension keyboard for PoKeys devices in CNC machines. The keyboard has 48 buttons with graphics that are equal to the most commonly used symbols and functions of a CNC machine. For providing additional feedback functionality, each key is equipped with a red LED backlight, which can indicate various states of the CNC machine. The upgraded version improves the reliability of the operation in machining environments and allows longer connecting cables to be used. PoNET kbd48CNC v2 can be directly connected to PoKeys57CNC v2 via the CAN bus connection. The keyboard can be customized and used as a general-purpose matrix keyboard without any additional software. However, applications that are aware of the keyboard (e.g. PoKeys Mach3 or Mach4 plugins) can make full use of its functionality. Two LEDs on the keyboard are used to indicate power supply and device status. »Power LED« (red color) switches on  immediately after the power supply is connected, while »Status LED« (green color) signals the current status of the device:

• Solid On: device is connected and working normally
• Slow blinking: no connection to Pokeys device
• Fast blinking: bootloader operation
• Solid Off: device disabled

The keyboard is also equipped with a light sensor, which can be used to monitor the level of the ambient light and adjust the brightness of the LEDs.

Connection using CAN bus
When using the kbd48CNC device with PoKeys57CNC with hardware revision 2.0, a direct CAN bus connection can be used instead of the PoNET interface. CAN bus is an industrial communication standard and is more robust to electrical noise in the environment. Moreover, longer cable connections are possible without sacrificing reliability. CAN bus is selected by moving the switch on the back of the device to position 2, as indicated in the picture below.

Note: firmware version 6 or higher needs to be installed on the kbd48CNC device for the CAN interface to be enabled. If the device does not respond to the initialization as described below, use the PoNET interface first to update the firmware of the kbd48CNC device. Once the firmware is updated, proceed with the use of the CAN bus.

Note: once connected to the PoKeys57CNC device over the CAN bus, make sure that option ‘Enable PoCAN’ in the Peripherals > PoExtBus Smart / PoCAN is enabled (if you check this box, click on ‘Send to device’ on the main screen to configure the device). The kbd48CNC device is automatically detected by the PoKeys57CNC and configured accordingly. The device will appear both in the PoNET devices list and the PoCAN devices list.

The kbd48CNC will appear both under ‘Peripherals > PoNET’ and under ‘Peripherals > PoExtBus Smart / PoCAN’, as shown below.
