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 AUX Cabs. Software support is now available starting with CS-105 software version 2.0. Hardware and software support is also available on the AUX Cabs port of the LCC WiFi Panel.
Contents
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. Only commands starting with XpressNet 3.0 and beyond are supported. X-Bus V1 and V2 commands are not supported.
Locomotive Long Addresses Less than 100
Locomotive addresses 1-99 are always DCC short addresses. Locomotive Addresses 100-9999 are always DCC long addresses.
Locomotive 28 Speed Step Mode
Locomotives are always controlled in 128 speed step mode. If an XpressNet device requests 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
By default, function 2 is hard-coded to momentary. All other functions are hard-coded to latching. Function momentary or latching mode can be customized in the command stations database and is loaded from the command station database if available. Function momentary or latching mode setup from an XpressNet device is not supported. Functions 29 through 68 are not currently supported.
| NOTE: Some throttles, such as the Lenz LH200 do not support momentary functions. On these throttles, F2 and other momentary functions will always be latching. |
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 using any of the consist members' addresses. The XpressNet throttle does not indicate consist membership.
Locomotive Real-Time Updates
If the locomotive is also under the control of another device, the XpresssNet throttle is notified. This is often indicated by a flashing display. However, unsolicited real-time speed and function updates are not provided due to the XpressNet protocol not supporting this feature..
Programming
Program Track and Program on the Main are not supported.
Model Time (Fast Clock)
Model Time (Fast Clock) is not currently supported.
Accessory Activation and Feedback >2044
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.
Supported and Unsupported Command Summary
Please see the XpressNet Documentation for additional information about the XpressNet protocol.

1 Only supports Broadcast Feedback for one address (pair) at a time.
2 The CS-105 reports version 3.6. It does support some version 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.
