Jay,

 

Adding a low cost second throttle depends upon your choice of command station and the type of add on throttle you desire. Your have two or more options depending upon your choice of DCC command station manufacturer.

 

The physical addition of a throttle is relatively simple. All that need be done is to extend a connection from the command station to the throttle interface device and any add on power devices required by the throttle interface.

 

As I understand the Power Cab system if you are planning on adding a second throttle to the Power Cab system you will first have to determine if you want a tethered throttle or a wireless duplex throttle. The minimum cost for a extra tethered throttle is the cost of the tethered throttle plus any tether interfaces you feel you may need plus the connecting cabling. The minimum cost for a wireless throttle is the cost of a duplex throttle and the cost of a duplex transceiver interface. The actual cost depends upon the hardware required and the place of purchase of said hardware.

 

As I understand the Zephyr system if you are planning on adding a second throttle to the Zephyr you first have to determine if you want a tethered throttle, a wireless duplex throttle, or a wireless Wi-Fi application. The minimum cost again will depend upon the type of extra throttle you desire and the place of purchase. The add on tethered throttle requires a tethered throttle plus any tether interfaces you fell you many need plus the connecting cable. The cost of a wireless radio throttle depends upon the cost of the wireless duplex radio interface and the cost of the wireless duplex throttle. Digitrax currently offers a third option and that is a Wi-Fi interface that can handle up to four additional Wi-Fi throttles. The Wi-Fi throttle option can be acquired by adding the Digitrax Wi-Fi interface to and Digitrax command station and then download a free Wi-Fi throttle app to an existing smart device (cell phone or tablet).
