PC Connections

Both of the DRC-Bus connectors on top of the SM2 are exactly the same electrically and mechanically. It makes no difference which of the two connectors the cable is plugged into. More than one SM2 can be connected by daisy-chaining the DRC-Bus cables from one SM2 to another. The SM2 Control Panel Application can handle up to 31 SM2 devices at any one time.

3-Wire DRC-Link Cable:

Connection to the PC is completed by making the following connections if you are using a 3-wire cable between the SM2 and the DRC-Link:

Plug the DRC-Link Cable into either one of the two SM2 top connectors.
Plug the DRC-Link Cable into the DRC-Link.
Plug the DRC-Link into a USB port on your PC.
Make sure all connections are made before launching the SM2 Control Panel Application.
Do not disconnect the USB cable while the application is running.

Important: Do not plug servos into the SM2 unless a system battery is also connected as it normally would be when the system is installed in a vehicle when a 3-wire DRC-Link cable is used.

Preferred 2-Wire DRC-Link Cable:

DRC-Link products sold after March, 2011 are shipped with a 2-wire DRC-Link cable that does not connect USB power to the SM2. Configuring the SM2 is more versatile when the 2-wire cable is used because the SM2 can be connected to gyros, receivers, servos, and any other accessories. The SM2 and all other components will be powered by your own system battery when the SM2 is configured.

Connection to the PC is completed by making the following connections if you are using a 2-wire cable between the SM2 and the DRC-Link:
