8 LCC CAN bus
In addition to LCC over WiFi, the CS-105 supports LCC over CAN using the dual RJ-45 sockets. In order to
perform well electrically, CAN requires a linear topology. Short stubs may be used, but should ideally be
used sparingly and kept under 6 feet or 2 meters. If you are using other wired LCC devices, a terminator is
required at each end of the LCC CAN bus. Two of these terminators are included with the system. It is easy
to know if a LCC CAN bus has been properly terminated, because there will be no unused RJ-45 sockets.
The CS-105 supplies power to the LCC cable, 400 mA in each direction.
9 Updating the Software Version
The CS-105 features a bootloader which can be used to perform software updates on the system in the
field at any time, assuming you have access to a firmware file. You can check the software version of the
system by using a TCS throttle and navigating to 8 Settings > 2 DCC System Settings > Status and then
scrolling down until you see “SW Ver:”
There are multiple methods by which you can update the firmware on the CS-105. You may update the
device wirelessly over WiFi, or wired through the LCC bus. Whichever method you choose to use, the first
step is to enter the bootloader. In order to access the bootloader on the CS-105:
1. Start with the device in an unpowered state. Unplug it if necessary.
2. Press and hold the button on the face of the device while plugging in the power.
3. Continue to hold the button for approximately 3 to 5 seconds. Release the button once you see LED
1 and LED 4 on the LCC header begin to alternately blink back and forth quickly. (Status LEDs are
described in detail in Section 1.)
Once you are in bootloader mode, you are ready to begin the firmware update process.
Note: When updating the firmware
via an LCC cable
using JMRI, the CS-105 will be switched from
operational state to bootloader automatically, thus you can skip these steps. The switchover process
disrupts WiFi connections, thus to update over WiFi, you must start from bootloader mode.

TODO TODO Describe how to perform the update over a wired connection. We need to have instructions
available for customers to update the firmware in their boosters or LT-50’s for example.
9.1 Updating Through D.E.P.O.T.
You must have the most recent version of TCS D.E.P.O.T. installed on your computer to download and
install this update into your device. If you do not have the program installed, you can
. Even if you already have the program installed, it needs to be updated to the latest
