LCC-LocoNet Gateway

LCC (Layout Command and Control)

1024 function LCC – LocoNet translator

This PDF is designed to be read on screen, two pages at a

time. If you want to print a copy, your PDF viewer should

have an option for printing two pages on one sheet of

paper, but you may need to start with page 2 to get it to

print facing pages correctly. (Print this cover page

separately.)

Overview LCC–LocoNet Gateway Image LCC–LocoNet Gateway Connectors The LCC®-LocoNet® Gateway interface provides a simple and easy way to connect between the NMRA LCC® bus and the Digitrax LocoNet bus. The LCC- LocoNet Gateway may be connected at any convenient point on the NMRA LCC® bus.LCC®...
Page 6: About Lcc
Because events can represent anything that happens on our layouts there is no presumed context nor meaning given to EventIDs. They are simply globally unique 64 bit numbers. Their only definition is what you give them. Well Known EventID LCC-LocoNet Gateway Manual Rev-a2...
Page 7: Consumer
EventIDs, then your nodes will work with his clock just as they did before. Line (channel) Each LCC-LocoNet Gateway contains 1024 I/O lines. (or channels) Each line has the ability to watch for 2 events (consumers) and to send out 2 events. (producers) Each line translates its events into the opposite protocol and queues them for sending out to the appropriate bus.
Page 8: Power, Serial Connections, And Indicators
® Compatible Connector The LCC data connection is made to the LCC-LocoNet Gateway via an LCC cable connected to either of the two RJ-45 connectors LCC1 and LCC2. The LCC wiring passes straight through both connectors. The LCC specification requires a minimum of 1’...
Page 9: Power Connections
If powered via the coaxial power input, then the LCC-LocoNet Gateway can act as the power source for a segment of LCC cable. The LCC-LocoNet Gateway acts as a convenient way to power a small LCC network including other LCC boards over standard RJ45 cables.
Page 10: Status Indicators
3.5 Status Indicators The LCC-LocoNet Gateway has four status indicators located near to the coaxial power connector. The green ON status indicator shows the power status of the LCC-LocoNet Gateway itself. The yellow Data indicator normally shows all data activity related to the LCC-LocoNet Gateway, and also any activity/error status during power up or a boot loader firmware upgrade.

LCC-LocoNet Gateway node. Node Address: Each LCC-LocoNet Gateway has a single node address that is used for CDI programming on the layout. Each individual LCC-LocoNet Gateway has its node address imprinted on the label on the front of the case.
Page 12: Input/Output Configuration
This will open the CDI tool and automatically read in the basic information for the node. This information is presented in a tabular format to allow a reasonably Expand the node to select 'Open Configuration dialog' LCC-LocoNet Gateway Manual Rev-a2...
Page 13: Initialization
5 Segment: The CDI is divided up into a number of segments to make it more manageable to configure. The LCC-LocoNet Gateway CDI consists of four main segments. 5.1 Segment: Identification The first segment shown will be the Identification. It includes the manufacturers name and node model plus any version information.
Page 14: Segment: Node Id
These will show next to the node number in the node tree, so short and descriptive is good. 5.3 Segment: Special Options The LCC-LocoNet Gateway has a number of supported special options. Some of these are node related options, and others are specific LocoNet commands that may be useful on the main LCC network.
Page 15: Node Power Monitor
5.3.1 Node Power Monitor LCC nodes may monitor their own power input and send notifications to the bus if they are in or out of specification. You may choose the EventID or use the defaults. 5.3.2 Master Power Control Master Power Control relates to the LocoNet messages GPON and GPOFF. (General Power On, and General Power Off) You can either select the default LCC well known power on and power off EventIDs, use the node defaults, or define your own.

(channel) is disabled until the 1 second timer is reset. Segment: Sections, Groups, and Lines The LCC-LocoNet Gateway has 1024 bi-directional translation lines. (channels) To prevent presenting 1024 different tab choices we chose to organize them as four sections of 256. Each Section is further divided into sixteen groups of sixteen lines each.
Page 17: Group
5.4.3 Line (Channel) Each line (or channel) controls the translation of one LocoNet item such as a turnout (output) or sensor. (input) The LCC-LocoNet Gateway also supports the NMRA extended accessory messages that are normally used for controlling signal aspects. The extended accessory messages support as many as 32 possible states for each message number.

Page 19: Trouble Shooting
To perform a very basic LCC-LocoNet Gateway sanity test perform the following steps: • Power up the LCC-LocoNet Gateway by plugging it into a powered LCC network, or by connecting a power supply to the unit. • The green power ON LED should come on.
Page 20: Boot Loader
8 Boot Loader 8.1 Firmware Upgrade If an update to your LCC-LocoNet Gateway firmware is needed, a program such as "Firmware Update" in JMRI version 4.6 or later is required. To enter Firmware upgrade mode: 1) Start JMRI and select "LCC".
Page 21: Warranty Information
LocoNet network there is no concern with connecting the LCC and LocoNet networks. 10 Warranty Information We offer a one year warranty on the LCC-LocoNet Gateway. This device contains no user serviceable parts. If a defect occurs, please contact RR-CirKits at: service@rr-cirkits.com for a replacement.
Page 22 Theory of operation Note: This information is from the OpenLCB web site and covers the operation of Gateways in general, not the LCC-LocoNet Gateway specificly. Gateways Gateways can route PCERs only to segments with nodes expressing interest by processing the other event messages, including Consumer and Producer Identified.
Page 23: Appendix: Theory Of Operation
Gateway “GB1” on the LOCONET side doesn't physically exist, but lives inside gateway “GA” and is represented by a routing table. Frames and messages on CAN are represented by [“source address”, “content”, “destination address”] triplets, those on LOCONET by [“opcode”, “destination address”, ”content”]. Not all messages are shown.
Page 24: Case 3: Node A1 Comes Up, Then Event X Is Sent
GA puts the Z message on the CAN segment, and A3 consumes it. GA puts the “Identify Consumers of Z” message on the CAN segment. A3 responds with “Consumer of Z Identified”. GA receives “Consumer of Z Identified”, forwards to GB1, which marks its routing LCC-LocoNet Gateway Manual Rev-a2...
Page 25 table to continue forwarding these. Case 6: Node A3 comes up, after event Z has been sent in the example above The gateway is up, but doesn't know about A3. GB1 has seen Z sent by B1, but has marked it as “do not forward” because there was no consumer for it on A. A3 comes up, gets a NID alias assigned, sends “AMD”...
Page 26 GB1. For each “forward” marker that has message type “Turnout Feedback” or “Sensor Message”, a message is generated on segment B. All further “Interrogate Switch Requests” will be ignored. A maximum of 10 messages will be sent every 100 milliseconds, in order to not overload the LOCONET bus. LCC-LocoNet Gateway Manual Rev-a2...
