XpressNet
XpressNETTM is the name given to the throttle network created by Lenz and also implemented by other model railway electronics manufacturers. Electrically, XpressNETTM is based around half duplex RS-485 and is a polled network running at 62.5 Kbaud. The CS-105 provides hardware support for this bus protocol through the RJ12 port labeled "Auxiliary". Software support is in development. A beta version is available, contact TCS for more information.

Unsupported Features
Some of the unsupported features are due to intrinsic limitations of translation between LCC and XpressNET. Support for some of the unsupported features may be added as time and development resources permit, and will be prioritized based on customer feedback.
Locomotive Addresses
Locomotive addresses 1-99 are always DCC short addresses. Locomotive Addresses 100-9999 are always DCC long addresses.
Locomotive Speed Step mode
Locomotives are always controlled in 128 speed step mode. If an XpressNET device may request 14, 27, or 28 speed step mode, the CS-105 will emulate the speed step mode and automatically translate an interpolated 128 speed step to the locomotive.
Locomotive Functions
Function 2 is hard-coded to momentary. All other functions are hard-coded to latching. Function momentary or latching mode setup is not supported. Functions 29 through 68 are not supported.
Locomotive Consisting
Consist setup is not supported. Consists setup on a native LCC throttle (such as the UWT-100 or UWT-50) will operate from an XpressNET device use any of the consist member's address. The XpressNET throttle does not indicate consist membership.
Locomotive Real-Time Updates
No indication is provided if the locomotive is also under the control of another device, and no real-time speed and function updates from other devices are provided.
Programming
Program Track and Program on the Main is not supported.
Model Time
Model Time (Fast Clock) is not currently supported.
Feedback And Accessories
Activation and Feedback is available for DCC accessory decoder addresses 1 - 2044. Addresses above 2044 are not supported. Lenz feedback input modules are not supported.

1 Only supports Broadcast Feedback for one address (pair) at a time.
2 The CS-105 reports version 3.0. It does support some version 3.6 and 3.8 commands.
3 Support for Command Station Busy is unnecessary because the CS-105 is always able to respond and never needs to report that it is busy.
