This section describes how specific components operate on the XC2055 and XC4055
On-Board LEDs
The four on-board LEDs have the following indicators:
| LED | Indication |
|---|---|
| Green power (Pwr) | Displays when the board is powered up and not in reset mode. Flashes during firmware update process. |
| Green file-system activity (Bsy) | Flashes any time there is file-system activity (on any storage device) |
| Blue (WiFi) | Illuminates when WiFi is connected and flashes when searching for a connection |
| Red status (Err) | Flashes a certain number of times to indicate which error is occurring. The flash codes are described below:
|
| A solid error light is displayed during the micro-controller update in BOS 9.0.36. Updating from an earlier OS version to BOS 9.0.36 or later will trigger this light. |
On-Board Switch / SVC Button
The SVC button is connected to the GPP_D6 GPIO on the processor. The RESET button is also sent to the PMIC (support micro), which when the button is asserted for four seconds will initiate a hard reset.
Reset Switch / GPIO Button
The RESET button is connected to the GPP_D5 GPIO on the processor. The RESET button is also sent to the PMIC (support micro), which when the button is asserted for four seconds will initiate a hard reset.
MicroSD Slot
The XC2055 and XC4055 have one MicroSD slot. High density memory cards with a capacity of up to 2TB, and SDR104 and microSC3.0 UHS-I ultra-high speed memory cards, are supported
Wireless Module
The XC2055 and XC4055 both have a dual antenna connection to allow users to install a BrightSign wireless module without disassembling the unit. BrightSign modules are configured to work with 802.11.N or 802.11.AC access points. This connection has a Bluetooth option.
