PURPOSE Procedure to setup a DB9 connector and where to purchase a tester, including how to use the tester on the DB9 connectors on the Micrologic Tunnel Controller Computers as well as how to interpret the results of the test. PROCESS DB9 Pin Out Guide Micrologic Controller DB9 Pin Out: Isolate the Brown, Gray, White, and Red wires. Cut the rest of the wires, we will not need them Grab Brown or Gray wire and insert it into the #2 hole on the head of the DB9 Grab White wire and insert it into the #3 hole on the head of the DB9 Grab Red wire and insert into the #5 hole on the head of the DB9 Attach the head to the body of the the adaptor. ICS Tunnel Master Jr. Output/Input Pin outs are as follows: Strip the CAT5/CAT6 cable to see all 4 pair wires Take Solid Blue wire only and wire it to GND on ICS phoenix connector Take Brown wire only and wire it to RXD on ICS phoenix connector Take White/Brown wire only and wire it to TXD on ICS phoenix connector Testing DB9 Where to Purchase - Amazon Link The RS-232 Tester that is recommended is the CableMax RS-232 LED Link tester DB-9 Male to DB-9 Female. NOTE: While other testers are available this article only covers recommended tester. How to Test The RS-232 Tester can be used to confirm functionality in 2 ways. OPTION 1: Plugging the female end into the Tunnel Controller COM Port and plugging the existing DB9-RJ45 adapter into the male end. OPTION 2: Plugging the female side into the Tunnel Controller COM Port and using a female configurable DB9 plugged into the male end. If this option is selected, a DB9 loop-back connector must be made from a female configurable DB9 adapter following the referenced configuration below: Pins 2 and 3 are terminated to each other in a loop. Pin 5 is seated but is not terminated to anything. End should be taped off for safety. How to Interpret Results The results of the DB9 Test can be interpreted base off the following diagrams: Orange lights are only observed with the DB9 Loopback module (Option 2) plugged in whereas the green lights will be observed when using the in-line method (Option 1). Anything deviating from the diagrams above is NOT a good result and could be indicative of an issue. This is an example:

PURPOSE Refer to this guide for help understanding and using the VNC Controller Viewer for the Tunnel Controller. You can use VNC Viewer to: View tunnel function/application statuses in real time Manually activate and deactivate tunnel functions/applications See the tunnel speed and average car length updated in real time Perform other tunnel functions (e.g., simulate a pulse, clear cars from the queue) NOTE: Do NOT leave VNC Controller Viewer open and unattended! Accidentally pressing the keyboard could disable a tunnel function/application. PROCESS Overview VNC Viewer Interface Tunnel Activity is at the top of the screen and displays important information about the tunnel activity: IP - The IP Address of the connected Tunnel Controller PC. Entry Sensor – this field reads EMPTY when there is no car in the eye. It changes to read MEASURING when a car is passing through the eye. Input Board – the communication status between the Tunnel Controller and the Relay Station Input Board. Local Time – The time the Tunnel Controller thinks it is NOTE: This time is important to remember when trying to locate information in the logs. App Time – The total time that the Tunnel Controller has run since the last restart. Speed – conveyor speed provides two options and these calculations are updated in real time: CPH (Cars per Hour) - The estimated number of Cars Per Hour that the track could support at the current speed. FPM (Feet per Minute) - The number of Feet Per Minute that the controller thinks the track is moving. Ver - The current running Tunnel Controller software version. Avg Car Length – The average of the measured length (photo eye) of all vehicles this calculation is updated in real time. This is used to calculate the CPH. Pulse/No Pulse – When the conveyor is running, this value should change to PULSE, indicating we are receiving information from the conveyor on its movement.. Orders – this is the number of vehicles currently in the queue (it will match the number of tickets shown in the Queue section directly below) Inputs on the left middle section displays a list of tunnel inputs and their statuses (ON and OFF) updated in real time. The list of inputs is always visible in the Controller Viewer interface. Not all the inputs in the list will be connected or configured. The most important ones are: Conveyor – A signal from the start stop board indicating we have requested that the conveyor start. Conveyor will continuously read ON when the conveyor is turned on. Entry Sensor – Photo Eye devices that measure the overall length of the vehicle. Tire Sensor– A floor mounted sensor that detects where the vehicles tires are. Outputs on the middle middle section displays a numbered list of all tunnel functions/applications and their statuses (ON and OFF) updated in real time. Highlight functions/applications using the arrow keys. The output list can only display 32 relays at a time. Use the keyboard arrow keys to navigate through the output list, up to relay 128. The selected output will be highlighted blue as shown above. By default, functions/applications are set to automatically turn on and off according to tunnel programming. Use the keyboard Space Bar to force devices on or off. No Icon – The device is set to Auto. The device will turn on and off based on programming. + Icon – The device is forced on. The system will keep the relay in the On position. – Icon – The device is forced off. The system will keep the relay in the Off position. Feedback – As devices turn on or off through programming or from using the space bar as described above, the output list will display their status. This can be used to verify the communication status of the output boards. Queue on the right middle section displays information about vehicles currently in the queue. The queue list displays all the wash services currently in the tunnel. Order Number – The number on the left of the list indicates what order number is attached to the wash. This number is helpful if searching the log files. Line & Arrow Color – Indicates that the vehicle is currently being measured by the photo eyes (Entry Switch). No icon indicates the car has not yet reached the eye. Green Arrow Line (–>) means the eye determined the car is long enough to proceed through the tunnel. Green Line (–) means the car has passed the eye. Red Arrow Line (–>) means the eye determined the car is too short (minimum length is 4’ and maximum length is 35’). Red Line (–) means the car is stopped at the eye or is out of order. Service Numbers– The services being applied to the vehicle, separated by commas. The numbers relate to the services programmed into the controller. 21 – Base Wash 22 – Base Plus Wash 23 – Platinum Wash 24 – Titanium Wash 12 – Full Retract 17 – Top Brush Retract 25 – Mud Flush 30 – Wet Down 31 – Dry Check 40 – Tire Shine Retract 41 – Open Bed 42 – Bike Retract 43 – Roof Retract 44 – Trailer Retract 45 – Low Profile 46 – Grill Guard 47 - Convertible Keyboard Controls - The bottom of the VNC image displays available keyboard commands. Output list quick access buttons – each number key changes the displayed outputs in groups of 32. 1 - Outputs 1-32 2 - Outputs 33-64 3 - Outputs 65-96 4 - Outputs 97-128 T – Toggle Simulated pulse Changing from live pulse to simulated pulse is useful when troubleshooting a pulse related issue. The system will automatically switch to simulated pulse when it detects abnormal pulse inputs. C – Clear Clears the queue of all vehicles. R – Reload Reloads the controller software. Clears the Queue of all vehicles. X – Exit Forces the controller PC to shut down the software completely and reload the software. Clears the Queue of all vehicles.

PURPOSE This document will guide you on saving a backup of the tunnel controller configuration if it is needed during troubleshooting later. PROCESS What are the reasons for backing up the config file? Bad Changes to the settings. Config file corruption. Replacing a controller to avoid programming a tunnel from scratch. How often should this be done? Before and after making changes. At least once a quarter. Guided Instructions Navigate to the Desktop on the site server and open VNC Viewer. Take note of the IP address. Open Google Chrome, type the IP address from VNC viewer in the address bar. Log in to the Logic Wash controller interface. If you do not know the credentials, contact your Regional Manager. After logged in, click Settings. Click Backup/Restore. Select Backup. Click Keep to finish downloading the config file. Click the folder icon to verify it downloaded, this will open the Downloads folder. Once verified that it has downloaded, close the Downloads folder window. Log out of the controller interface.

PURPOSE Change tunnel controller pulse input in case of a input failure. PROCESS On the site server computer, open the Micrologic Tunnel Controller shortcut from the desktop, LogicWash Controller. if prompted for username/password, check with site management, if site management is unable to provide the necessary info please reach out to Mister IT. Once we are logged in, the controller web page will look like this: Here we want to select the 'Settings' option. At the settings page, we will have an option labeled 'Pulse Input Channel' In the drop-down menu, we will have the options to select from 0 - 16 * 0 means the feature is disabled and the software is reading the pulse from the default pulse input. If you move the pulse to input 3 then the Pulse Input Channel needs to be changed to 3. On DRB TCS, the input letter corresponds with the input number (e.g., Input C equals Input 3) Once we have our new Pulse Input Channel set we need to: Press 'Save' on the right hand side of the page. Select the 'Backup/Restore' option on the top of the page. Now we need to select the option 'Commit + Reload' in order for the changes to take effect.
