Hello All

I have an ITT HQ series Sound module for my grade crossing. WWW.ittproducts.com

I also have the Trainspeed Flashmaster. WWW.trainspeed.com

Has anyone hooked these together and if so what would be the connections.

Here’s the outputs of the flashmaster

Flashmaster

1 Light 1 Connect to one of the two light wires from the flashers

2 Light 2 Connect to the other light wire from the flashers

3 +5V Available for incandescent lights

4 COM_RES Connect to the common wire from the flashers if your

flashers do not have resistors installed

5 COM Connect to the common wire from the flashers if your

flashers have resistors installed

6 GND GND (0V) connection

7 Cascade Input to master unit when cascading two units together for

more then two track operation

8 BELL_neg External bell unit trigger – low going signal

9 BELL_pos External bell unit trigger – high going signal

10 XOVER Crossover input (see advanced options)

Thanks

Pin 9, BELL Positive trigger, is the only connection required between the two boards. Connect this terminal to the ITT board’s “trigger” input. The ITT module gets its own separate power input.

Thanks I’ll try it tomorrow.

I Just received a call from George of Itt who went through it with me. Turns out I have a version that does not stop when you remove the low voltage. His current version does. He’s sending me a replacement unit no charge.
Excellent service
