nwts compatible devices
The objective of this page is to list devices that are compatible with nwts and were time sync was tested.
It's not limited to Nixie clocks.

Direct compatibility - tested by azevedo devices
  • PV Electronics
    • Halo
    • Frank 3
    • Spectrum 18, 568 and 1040
    • IN-8 clock
    • NL840/CK8754 clock
    • QTC clocks
    • Kit for Remote Displays
  • Mr Nixie
    • All of Mr. Nixie's clock line
  • Akafugu
    • VFD Modular Clock
      • As this clock does not have a TRS jack connector, a cable needs to be adapted for the GPS pins
  • Yan Zeyuan - Nixie Clock Home
    • New VFD IV-11 clock
  • GoodNixieTime
    • IN-4 dekatron GPS nixie clock
Reported compatibility
  • Jeff Thomas GPS II
    • Requires GPS II hardware adaptation and minimum nwts firmware version 1.7
  • Dutchtronics AVR Osciloscope Clock
    • Requires minimum nwts firmware version 1.6
    • More information can be found here!
  • Swiss Nixie SUNIX-S 
  • Nocrotec Blue Dream clocks
    • nwts must be set for RS-232 (J3 closed, J1 and J2 open)
    • nwts speed needs to be set for 4800 bps
    • Blue Dreams have a known 2s delay compared to other clocks if using the same time source. This drift can be corrected by adding "2" seconds on the "Clock drift correction" menu (nwts versions 2.x and up)
    • You need to make a cable connecting matching the pin-out of Blue Dream clock (left) with nwts pin-out (right):

  • Tube Hobby NCV2 Nixie Clock
    • The Tube Hobby clock uses a 6 pin 'Mini-DIN' connector intended for a GPS receiver outputting RS232 level NMEA data at 4800 baud. The connections and configuration for this clock are as follows:
    • DIN Pin No.    Function
         1.                 GND
         2.                 +5V
         5.                 Data
    • nwts baud rate: 4800 Baud
    • nwts output: Pseudo RS232
  • Yan Zeyuan Nixie Clock Home
    • IV-18 clock (v1.22) - TTL both at 9600 and 4800 bps
    • IV-11 clock
    • Crystal Castle VFD Clock
      • Baud 4800, RS232. This clock only syncs at Mondays, 08:00. Because of this, DST might only be updated after Monday 08:00.
    • IN-8-2/IN-14 Nixie Clock v1.02
      • Both 9600 and 4800 baud, TTL. Clock is shipped 9600 default setting. Can be switched to 4800/9600 using undocumented function with remote. No menu available to change this.

        Power off clock with remote control(clock still running in standby) using the keypad, enter 9600 or 4800, followed by OK to change the baud rate to match nwts'.
  • Oscilloscope Clocks and Nixie Clocks (Howard Constantine)
  • GRA & AFCH
    • Nixie Clock Shield NCS314 v2.3
  • XMAS-ICETUBE
    • Need to had to add a 3.5mm TRS to the clock
