SHD2 - Dual Signal Head Decoder

The SHD2 is a DCC compatible signal head accessory decoder. It can control up to two signal heads and is compatible with JRMI Signal Heads. It can drive four individual LEDs (4 colors) per head. A total of eight outputs


Board size: 0.5" X 1.25"

Features:
• DCC compatible signal accessory decoder
• Control 2 signal heads (4 aspects each)
• Easy signal mast wire connections
• Built-in resistors for LED drive
• Prototypical lamp fade
• Brightness adjustment
• Independent control of lunar aspects
• JMRI signal head compatible
• Digitrax signal mast compatible
• Connector pins and heat shrink tubing included

Operation:
The SHD2 works out of the package with no programming (address 1 for head 1 and address 2 for head 2). Additional SHD2s will require address changes. The SHD2 responds to DCC signal decoder packets as defined by the JMRI 'DCC Signal Decoder'. The SHD2 turns on an LED based on an address and aspect number. 

The SHD2 is not compatible with incandescent lamps or LEDs with integrated resistors.

Application:
One possible way to mount the SHD2 is with an adhesive backed wire clip such as the Gardner Bender (GB) GWC-1510. Before inserting the SHD2 in the wire clip, release some of its tension by opening the clip several times. The SHD2 should slip into the clip relatively easy to avoid any physical damage.

If you are having custom signal masts made, consider having the wires coming out of the mast 10" to 12" long. This makes connecting the wires to the SHD2 easier compared to very short wires.

The following diagram shows how several SHD2s can work as a signal system in a NCE system. This also applies to any DCC system that can interface to JMRI. Based on turnout state and block status, JMRI provides the logic that determines which signal head aspect (color) should be on.
