View source for CS-105 Throttle and Device Capacity

The CS-105 has several interfaces for connecting throttles and other devices. There are capacity limitations to these interfaces out-of-the-box, however the CS-105 can be paired with a number of accessories in order to expand the capacity.

== Wi-Fi ==

=== Access Point Mode ===
In this mode, the CS-105 broadcasts a WiFi SSID which supports WiFi client connection of up to four devices (throttle, PC, smart phone, etc...).

=== Client Mode ===
In this mode, the CS-105 connects to an en external WiFi access point (router). It can accept connections from up to 10 other devices that are also connected to the same network.

== LCC CAN Bus ==
The CS-105 integrates an NMRA Standard LCC CAN bus through a dual RJ-45 jack (labeled on the enclosure). This bus topology must meet the following requirements:

# Maximum length of 1000ft / 300m.
# Linear in topology with branches or T's limited to 10ft / 3m.
# Branches and T's should only be used for wired throttles.
# For each connected device, the maximum length should be reduced by 20ft / 6m. This means the practical limit [electrically] is around 48 connected devices.
# Contain exactly two terminators at the two farthest ends of the bus.

These requirements ensure reliable operation in all environments. Practically speaking, the LCC CAN bus is typically resilient to deviation from these from some of these requirements. An LCC Repeater can be used to extend the LCC Can Bus beyond these limits. TCS recommends the [https://www.rr-cirkits.com/ RR-CirKits] LCC Repeater for this purpose.

== Auxiliary Bus ==

=== Cab Bus Mode ===
When running in Cab Bus mode (compatible with devices from NCE, Ramtraxx, SystemOne, and WifiTrax), there is a limit of 62 connected devices (throttles, etc...). For more information, see the [[Cab Bus]] documentation page.

=== XpressNET Mode ===
When running in XpressNet mode (compatible with devices from Lenz, Roco, ZTC, and others...), there is a limit of 31 connected devices (throttles, etc...). For more information, see the [[XpressNET]] documentation page.
