pnix-util

This package implements command line and library utilities for managing Control Solutions LLC Phoenix Motor Controllers. See http://controls.com.

Installation

$3

These utilities are designed to work on Windows, Mac, and Linux computers.
You must install the following pre-requisites:
* NodeJS (version 10.22.x or 12.18.x) from https://nodejs.org
* Any drivers required for the interface hardware you intend to use

Install the command line utilities by using the following command in a terminal window:
npm install -g @csllc/pnix-util

Check the version using the command:
npm ls -g @csllc/pnix-util

Update to the latest version:
npm update -g @csllc/pnix-util

After upgrading NodeJS and/or pnix-util, the utilities may fail to run. This is most likely because the package dependencies also need to be upgraded or rebuilt. This can be done by running:
npm -g -f install

$3

The utility supports different physical connections:

#### GridConnect CAN-USB-COM
This adapter allows a CANBUS network to be attached to the PC using a USB port. No driver is required for OSX; Windows drivers can be found here:
Through Windows 8
Windows 8 RT Driver

#### PEAK-System PCAN-USB
This adapter allows a CAN Bus network to be attached to a PC using a USB port. The @csllc/cs-pcan-usb dependency package includes the necessary drivers for Windows and macOS.

Use --connection=can with -l to query adapters, and --port=pcan-usb_XX with the commands below to specify a PCAN-USB adapter, where XX is the driver-assigned port number.

#### Kvaser Leaf Light v2
This adapter allows a CAN Bus network to be attached to a PC using a USB port. The @csllc/cs-canlib dependency package includes the necessary driver for Windows. Under Linux, the kvaser_usb kernel module must be available to use this adapter with SocketCAN.

Use --connection=can with -l to query adapters, and --port=canlib_XX with the commands below to specify a Kvaser adapter, where XX is the driver-assigned port number.

Under Linux, Kvaser USB adapters are handled as SocketCAN devices; the PiCAN2 instructions will apply instead.

#### PiCAN2 for Raspberry Pi
This board adds CAN Bus functionality to a Raspberry Pi through the Linux SocketCAN driver, included in the Raspberry Pi OS.

Use --connection=can with -l to query adapters, and --port=socketcan_canXX with the commands below to specify a Kvaser adapter, where XX is the operating system-assigned port number.

Configuration

Once the utility and the physical connection is in place, you will need to set up the connection parameters.

$3

Use the -l option to list all available connections:
pnix -l

Identify the port that connects to the controller. If needed, run the command without the hardware adapter attached, then with it attached. The port that appears is the one you want. On Windows, the port is probably named something like 'COM23' though the number may be different.

$3

Now that you know the port name, use the -f option to find the controllers. Note that at least one controller must be powered on, and connected via a properly terminated CANBUS.
To find controllers on a 250Kbaud canbus, using port COM23, you would use the command:

pnix -f --port=COM23 --canrate=250000

The utility will output the ID of any controller(s) found on the CANBUS. Often, the controller will be ID 128.

$3

The configuration can be saved as the default by adding the --save option:
pnix -f --port=COM23 --canrate=250000 --unit=128 --save

pnix-watch

The pnix-watch command waits for status information from a particular controller and displays it on the screen. Assuming you have a properly connected and configured system, simply use the
pnix-watch command. You can over-ride configuration using command line switches. For example:
pnix-watch --unit=130

pnix-config

The pnix-config utility loads a configuration file into the unit. Normally these files will be supplied by Control Solutions - modifying the contents of the file may lead to unexpected results.

pnix-config load setup.txt --shadow
The --shadow option loads the configuration temporarily - it will take effect immediately, allowing you to check that it works as intended. If the controller is power cycled, the changes will be lost.

To make the changes permanent, load the file without the --shadow switch:
pnix-config load setup.txt
After power cycling the controller, the new settings will be in effect.

pnix

The pnix command allows individual configuration items to be changed.
For example,
pnix read sconfig deadband returns the deadband setting.
pnix write sconfig deadband 0x10 changes the deadband setting to hex 10 (decimal 16)

The above command changes the shadow (active copy) of the configuration. To make the change permanently, use the alternate commands:
pnix write config deadband 0x10
