Operation

Charging and Battery Monitoring

The PT301 uses a USB Type-C connector for both charging and for optional local communication. To charge the battery, connect the device to a USB power source via the Type-C USB connector.

Whenever USB Power is applied to a PT301, the device will reset.

Battery Percentage reporting is available on the PT301 in the CUWB Viewer.

For battery safety, the PT301 will enter ship mode when the battery becomes too depleted. To recover and exit ship mode, charge the tag fully.

Ship Mode

The PT301 is shipped in a low-power ‘ship mode’ to protect the Li-Ion battery during storage and transport. When a PT301 is in ship mode, it is not receiving power from the battery. The PT301 will not search for a CUWBNet or use it’s LED indicator.

Exiting Ship Mode

To exit ship mode, plug the PT301 into a powered USB port. Applying charge power will wake the device, and it will begin searching for CUWBNets in the area.

For first-time operation, the PT301 must be connected to a powered USB port to turn on and exit ship mode. This will cause the PT301 to automatically attempt to join any CUWBNet that is within range of its UWB transceiver.

Entering Ship Mode

The PT301 can be placed back into Ship Mode by using the Device Manager in the CUWB Manager. This will disconnect the battery internally for long term storage or shipping the PT301.

The battery should be partially charged (~50-60%) when using Ship Mode.

Communication

When connected to a USB host the PT301 will enumerate as a USB device with the VID:PID of 0x0483:0x5740 and USB speed grade Full Speed (12 MBit/s).

To connect with PT301 and configure them to be a wired device in a CUWBNet, see CUWB USB Driver for additional information.

The PT301 will communicate over USB with the Ciholas Serial Protocol. For additional information on serial packet formatting, see Ciholas Serial Protocol.

Firmware Updates

The PT301 can be updated with new firmware releases by using the CUWB Manager. The PT301 supports both Over-the-Air (OTA) by UWB and wired updates by USB. See Firmware Updates for instructions. The latest firmware packages are available on the Software Downloads page.

CUWBNet Operation and Configuration

CUWBNet Join

After exiting ship mode, the PT301 automatically attempts to join any CUWBNet that is within range of its UWB transceiver. To conserve energy, the device listens on a periodic schedule. Initially, the time between searches is low to allow for a fast join.

If no CUWBNet is found, the period between searches increases over time. Eventually, if no CUWBNet is detected, the device will utilize the slowest search period. The slowest search period is once every 640 seconds. See CUWBNet Search in the CUWB Manager Manual for additional information on search periods.

The search period described above is reset any time charging power is provided to the PT301. If a device is taking longer than expected to join, plugging it into a powered USB port will reset the listen period and allow it to join more quickly.

Wake-on-Shake will also modify the listen period for tags. See Wake-on-Shake section below.

CUWB Configuration

PT301 devices must be added to the CUWB configuration in order to join a CUWBNet and begin beaconing. Details regarding PT301 setup and configuration for the CUWB RTLS can be found in the CUWB Manager.

Wake on Shake

The PT301 supports Wake-on-Shake CUWBNet Search. Wake-on shake is enabled by default and allows the device to enter low-power sleep when not participating in a CUWBNet. When the device is steady and no motion is detected, the device will enter a low-power mode searching for CUWBNets infrequently. Any time the PT301 detects motion, it will exit the low-power mode and search for CUWBNets at a much higher rate.

When plugged into USB power, the PT301 will hunt for a CUWBNet every 5 seconds regardless of motion.

The Wake-on-Shake feature is adjustable when the PT301 is active on a CUWBNet. For detailed information on this feature and its settings, see Wake-on-Shake CUWBNet Search.

LED Indication

The PT301 has a tri-color (RGB) LED for conveying device state to users. In normal operation1 the device state can be determined using the table below:

Status Battery Color ON Time Period
ON CUWBNet <20% Red 10 ms 1.0 s
ON CUWBNet 20-100% Green 10 ms 1.0 s
OFF CUWBNet <20% Red 10 ms 10.0 s
OFF CUWBNet2 20-100% Green 10 ms 10.0 s
Charging 100% Green FULL N/A
Charging 75-99% Magenta 900 ms 1.0 s
Charging 50-74% Magenta 500 ms 1.0 s
Charging 0-49% Magenta 100 ms 1.0 s
Power On Reset3 N/A Blue 500 ms N/A
USB Enumeration4 N/A White 0.25-5.0 s N/A

1. This table denotes normal LED operation. The CUWB Manager can be configured to show different patterns on the LEDs.
2. Off CUWBNet behaviors are a double green blink, and will reduce in frequency for power savings the longer the device is off of the CUWBNet. This may be as long as 640 seconds if wake-on-shake features are enabled.
3. Power On Reset (POR) occurs only on system reset. This will happen when on powered USB cable insertion, on reboot after firmware update, and when the device resets due to system watchdog. If a device remains on with a solid blue led, the firmware is invalid.
4. USB Enumeration time may vary.

The LED on the PT301 can be completely disabled. See the CUWB Manager Reference Manual for configuration details.

Error Handling

The RGB LED also conveys error states to the user. An error is indicated by a 500 ms red flash followed by a color sequence.

The following color sequences are used to decode error states:
