Interface Description:
- J1: power interface, 5.5-2.1, onboard anti-reverse diode
- JP1: 4PIN, unwelded, directly connected with J1, suitable for wiring out
- D3: power indicator, green indicator light on when power on, otherwise light off
- RP1: frequency adjustment potentiometer, 0-5V output voltage range, chosen by JP8 jumper whether to use it or not.
- JP8: jumper, choose to use potentiometer or not
- JP5: IDC5 x 2P, suitable for connecting rubidium clocks with flat cables,pay attention to direction.
- JP3: directly connect rubidium clock
- JP2: EFC outlet socket, not welded, directly connected to P1-SMA port
- P1: EFC pin, input 0-5V, fine tune the frequency of the rubidium clock. If RP1 potentiometer is selected for connection, it is recommended to suspend the pin.
- P2: Rubidium clock 10M output, board mounted 0.1uF DC isolation capacitor
- JP7: 10M outlet socket, not welded
- D2: Locked LED, red; LED on for unlocked; LED off for lock
- JP4: Lock the pin and connect it directly to the rubidium clock pin
- JP6: Lead out LPRO-rubidium bulb lamp voltage and internal VCXO voltage control, communicate TXD and RXD with LPFRS and XHTF-RS232.
- Size: 70 x 55 x 35mm
- Fixing hole size: M3.0; 63 x 33mm

Precaution:
- If the height is not suitable, the height can be adjusted appropriately by adding or reducing shims;
- When using, it is necessary to fix the circuit board to prevent poor contact;
- When adjusting the potentiometer, be sure to fix the circuit board properly, otherwise it may cause poor contact and significant frequency fluctuations.

FAQ:
Q: What should I do if the green light on the circuit board does not light up after power on?
A: Check if the power supply is plugged in properly and if the power supply is sufficient. It is recommended to use a 24V 2A power supply (not included). If the power supply is normal, it may be a malfunction of the rubidium clock. It is recommended to check the rubidium clock.

Q: After powering on, the green light is on, while the red light remains on and cannot be extinguished. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.

Q: Just powered on, the green light and the red light is on. After a while, the red light goes out, and after a while, the red light on again. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.

Q: Just powered on, the green light and the red light is on, and after a while, the red light becomes dim, but it doesn't go out. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.

Q: Just powered on, the green light is on, but the red light remains off. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.

Q: After connecting the potentiometer, no matter how the potentiometer is adjusted, the frequency cannot be adjusted to 10M
A: The rubidium clock needs to be adjusted or has a malfunction. It is recommended to check the rubidium clock.

Q: After connecting to SMA, why cannot check the 10M output?
A: Check if the SMA interface has good contact. If contact well, there is a possibility of rubidium clock malfunction. It is recommended to check the rubidium clock.
