Get Firmware Version

4/15/2024

Firmware Version: 1.0.6.1

Update Section 2 for FP12 Duo and Trio

Q60 has 1x Nexus Link Type-C (Port1) and 1x Nexus Link Type-M (Port2) channels
The Type-M channel is connected to both the 2x pumps and 2x fans by default

1. Get Q60 Pump Info

This protocol is used to get pump info and is also used as a flag to check if Nexus software is in control
If the software does not call this function within 5 seconds, Q60 cooling and LED control will revert back to the default state (motherboard/temp/firmware mode)

Pump info includes:

Temperature (in/out)
Pump RPM
Raidator Fans (exhaust/intake)
Current Cooling Mode
Nexus Link AmpScale Warnings

Serial.Write

Byte 0	Byte 1	Byte 2	Byte 3
FF	CC	0x01 (Get Status)	0x00 (Pump)

Serial.Read

Byte 0	Byte 1	Byte 2	Byte 3	Byte 4	Byte 5	Byte 6	Byte 7	Byte 8	Byte 9	Byte 10	Byte 11	Byte 12	Byte 13
FF	CC	0x00	(reserved)	(reserved)	In Liquid Temp_H	In Liquid Temp_L	Out Liquid Temp_H	Out Liquid Temp_L	Pump RPM_H	Pump RPM_L	Fan Exhaust/Intake	Current Cooling Mode	Warnings

Byte 3 & 4: Reserved
Reserved

Byte 5 & 6 (7 & 8): In/Out Liquid Temp

Using the algorithm below to get the current voltage

vol = 3.3 * ((TH * 100) + TL) / 4096

Get the corresponding temperature from the voltage using the following table
Temperature Chart

Byte 9 & 10: Pump RPM

int RPM = (60 * 1000 / ((Byte 9 * 100 + Byte 10 )/ 10 * 4));

Byte 11: Fan Exhaust/Intake(Determine only on the first power-on)
Intake: 0x01
Exhaust: 0x02
No-Fans connected: 0x03 (no fans detected on Type-M channel)

Byte 12: Current Cooling Mode
The current cooling mode Q60 is running
Software: 0x01
Motherboard: 0x02
Temp Mode: 0x03

Byte 13: Warning
0x00: None
0x01: Too many devices connected to a single channel (more than 18) -> Flashing Red (per second)
0x02: Too many devices connected across all channels (more than 34 across 2 ports) -> Constant Red
0x03: Too many LEDs connected on a single channel (more than 249) -> Constant Yellow
0x04: Type-C channel (Port1) current overload -> Flashing Orange (per second)
0x05: Type-M channel (Port2) current overload -> Flashing Orange (per second)

Since this protocol can only return 1 state at a time, we will prioritize the warning as following sequence
03 -> 04 -> 01 -> 02 -> 05
(The detail warning status will return all warning state at the same time, please check here)

Q60 has a total of 15A/12V and each port can have a maximum of 8A/12V
Since Q60 has 2 pumps inside the radiator which use 0.4A/12V * 2 = 0.8A/12V, the maximum amperage of the 2 ports is 14.2A/12V
Port1 (Type-C) is designed to connect up to 18 devices, but if there's current overflow, Nexus Link AmpScale will slow down all connected fans to 2000 RPM

10 fans -> 3000 rpm
> 10 fans -> 2000 rpm

Light strip current

LS10 -> 0.2A/12V
LS30 -> 0.6A/12V
LN40/60 -> 0.4A/12V
LN70 -> 0.44A/12V

Fan current

FP12 Single: 0.7A/12V (3000rpm), 0.2A/12V (2000rpm)
FP12 Duo: 1.4A/12V (3000rpm), 0.4A/12V (2000rpm)
FP12 Trio: 2.1A/12V (3000rpm), 0.6A/12V (2000rpm)

Port2 (Type-M) is connected to the 2 fans on the radiator by default, so we need to maintain the maximum RPM of 3000
If Port2 experiences current overload, it will sequentially disable the extra devices

2. Get Channel Info

Q60 can connect to Nexus Link secondary nodes (such as FP12, LS10, LS30)
When the devices are connected, Q60 will know what each device is and will return the corresponding information
Nexus software can use this function to get device info from both Type-C (Port1) and Type-M (Port2) channels

Serial.Write

Byte 0	Byte 1	Byte 2	Byte 3
FF	CC	0x01 (Get Status)	Channel (Port1 or Port2)

Serial.Read
!12 bytes is one set for a device (only the very first byte 0 & byte 1 will be FF CC
Each port can read 19 devices (but the user is only allowed to plug in 18 devices, since we need the 19th one to know if there's more than 18)
This protocol will return 240 bytes (12 more bytes are reserved)

Get the corresponding temperature from the voltage using the following table
Temperature Chart
Calculate Temp_H & Temp_L

For example:
If we want to get 30 degrees
30 degrees = 2.669 voltage
Temp_H = (byte)(int)(2.669 * 10);
Temp_L = (byte)(int)(2.669 * 1000) % 100;

8. LED Streaming

Q60 has 4 LED channels (which is not to be confused with the Nexus Link Type-C (Port1) or Type-M (Port2) channels)
We have the default LEDs (HYTE Logo/LCD LEDs) on the same channel
Channel 1 -> Device Port1 (Type-C)
Channel 2 -> Device Port2 (Type-M)
Channel 3: LCD LEDs (42 LEDs)

Channel 4: HYTE Logo (4 LEDs)

! Once Nexus software starts sending an RGB signal, firmware will automatically stop firmware animations until Nexus software doesn't send the flag protocol (Get Pump Info)

Serial.Write
