ADC Sensor (PH2.0)	ADC, GND	Analog sensor input

Power On

Connect the USB Type-C cable to a 5 V power source (USB charger, power bank, or computer). The display boots in ~3 seconds and shows the Dashboard page.

Open Settings

Tap the Settings tab at the bottom of the screen (gear icon). The Settings page shows connection options on the left panel.

Select WiFi

Tap the WiFi button at the top of the left panel (it is selected by default).

Enter WiFi Credentials

Tap the SSID field and type your WiFi network name using the on-screen keyboard.
Tap the Password field and enter the WiFi password.

Default: SSID = Battpulse | Password = Battpulse

Select BMS Type

Choose your BMS from the dropdown:

Moonitor16S — Original Moonitor BMS protocol
BattPulse — BattPulse Leader BMS protocol

Enter BMS IP or Scan

Type the BMS IP address manually, or tap Scan Network to automatically discover BMS devices on your WiFi network. Discovered devices appear as buttons — tap one to select it.

Tap Connect

Tap the Connect button. The status indicator turns green when connected. Data starts flowing to the Dashboard immediately.

5. Setup — CAN Bus Connection

CAN Bus mode provides the fastest, most reliable connection. Data is received directly from the BMS at 100 ms intervals with zero network dependency.

Wire the CAN Cable

Connect the included PH2.0 CAN cable to the CAN port on the display:

Wire	Connect to BMS
CAN-H	CAN High
CAN-L	CAN Low
GND	Signal Ground

Power On

Connect 5 V USB power. The display boots and shows the Dashboard.

Select CAN Bus Mode

Go to Settings → CAN Bus tab at the top of the left panel.

Configure (Usually Not Needed)

The display ships pre-configured for BattPulse BMS defaults:

Setting	Default	Description
Baud Rate	500 kbps	Must match BMS CAN speed
Mode	Normal	Normal = TX+RX, Listen-Only = RX only
Timeout	1000 ms	Data timeout before "stale" warning
CAN IDs	0x300–0x370	Pre-set for BattPulse protocol

If you are using a BattPulse BMS, no changes are needed.

Tap Connect

Tap Connect. The CAN Status sub-page shows live diagnostics: message count, parse rate, and error counters. Data appears on the Dashboard within 1 second.

Page	What It Shows
📊 Dashboard	SOC arc gauge with percentage and remaining Ah Pack voltage, current, power (W), charge/discharge direction Cell count (xS), max cell, min cell, cell delta (mV) Temperature probes with sensor names and colour-coded values I/O states — Charge FET, Discharge FET, Balancing Status indicator and event string from BMS Fault/warning banner when active
🔋 Cell States	Grid of all individual cell voltages with colour-coded borders Average, max, min cell voltage Cell delta (imbalance) value Current and balancing status Grid automatically resizes for 6S–16S packs
⚙️ Settings	Connection type selector: WiFi / CAN Bus / RS485 WiFi: SSID, password, BMS type, IP, network scanner CAN Bus: Baud rate, mode, timeout, CAN ID config, diagnostics Display: Screen timeout, brightness slider Restart Screen button (reboots the display controller) Reset BMS button (CAN mode only — sends restart to BMS)

Setting	Options	Default
Screen Timeout	Always On, 30s, 1/2/5/10/30 min, 1/2/3/5/6/8/12 hours	5 minutes
Brightness	10% – 100% (slider)	100%
Restart Screen	Button — reboots display controller	—

Setting	Description	Default
SSID	WiFi network name	Battpulse
Password	WiFi password	Battpulse
BMS Type	Moonitor16S or BattPulse	Moonitor16S
BMS IP	IP address of BMS on network	192.168.1.100

Setting	Description	Default
Baud Rate	125 / 250 / 500 / 1000 kbps	500 kbps
Mode	Normal (TX+RX) or Listen-Only (RX only)	Normal
Timeout	Data timeout in ms	1000 ms
Status Base ID	CAN ID for pack status frames	0x300
Cell Base ID	CAN ID for cell voltage frames	0x330
Temp Base ID	CAN ID for temperature frames	0x350
I/O ID	CAN ID for I/O state frame	0x360
Fault ID	CAN ID for fault/warning frame	0x370

Symptom	Solution
Screen shows "No Data" / "Waiting for BMS frames"	WiFi: Check that the SSID/password are correct and the BMS IP is reachable. CAN: Verify wiring (CAN-H to CAN-H, CAN-L to CAN-L). Check baud rate matches BMS.
WiFi connects but no BMS data	Verify BMS IP address. Tap Scan Network to discover BMS devices. Make sure the correct BMS Type is selected (Moonitor16S vs BattPulse).
CAN: high RX Errors count	Check CAN bus termination. The bus needs exactly two 120 Ω resistors (one at each end). Verify baud rate setting.
Cell count shows wrong number	Cell count is auto-detected from CAN/WiFi data. Ensure BMS is configured for the correct number of cells.
Temperature probes missing	Probes are auto-detected. Only active (non-zero) probes are displayed. Check BMS sensor configuration.
Screen is unresponsive	Go to Settings → Restart Screen or power-cycle via USB cable.
Display is dim	Go to Settings → Brightness slider and increase to 100%.
BMS needs restart (CAN only)	Go to Settings → CAN Bus → CAN Status tab and tap Reset BMS. Confirm in the dialog. The BMS reboots in 2–4 seconds.

🔴 Important Safety Instructions

This display is a monitoring device only. It does not control the battery pack directly.
Do not expose to water, extreme humidity, or temperatures outside -20 °C to +70 °C.
Use only the provided USB cable or a certified 5 V USB power source.
If using battery power, use only a single 3.7 V Li-Po cell (max 2000 mAh). Do not use multi-cell battery packs.
Do not disassemble the unit. There are no user-serviceable parts inside.
CAN Bus wiring must follow proper automotive/industrial practice with correct termination.
Always verify BMS data against the primary BMS interface before making safety-critical decisions.
