Program and test compatible two-wire decoders

This Tonick handheld programmer/tester is for Watermation, Underhill and TW-DIAS-style two-wire decoders. It allows a compatible decoder to be addressed and checked before installation or during fault finding.

Important compatibility warning

• For two-core/two-wire decoder products only
• Not suitable for programming three-core Toro SC3000/Trident-style decoders
• Confirm the decoder family before connecting the tester

Use

Connect the decoder as specified in the Tonick instructions and allow it to power up before programming; the listing recommends approximately 15 seconds. Keep test connections clean and dry and verify the programmed address before installing the decoder in the field.
