This user guide describes how to seamlessly integrate the Roster Athletics platform with the FinishLynx timing system.

This guide is divided into a few sections below:

What do you need to do to set up the integration?


The RosterAgent program is a small program that allows communications between the Roster platform and FinishLynx so that they can stay in sync with each other during the competition for start lists upload from Roster to Lynx and results download and sync from Lynx to the Roster platform (and immediately in the app).


Now you should have everything ready to start the integration. Make sure you have the following three programs open: 

  1. Roster Athletics in a browser
  2. FinishLynx running
  3. RosterAgent running


Integration type

In the RosterAgent program, you will need to select the integration type by choosing either Serial port or shared LIF files per the instructions below in order to share information data between Lynx and Roster.


  • LIF files: Use this option if you are using the same computer or you are using a shared file folder between computers (e.g. one computer running Roster/Roster Agent and another computer running FinishLynx).
  • Serial port: Use this option if you have connected one computer running FinishLynx with another separate computer running Roster Athletics via a serial cable. 


LIF files

If you select LIF files as the integration type, then you will have to select both an input and an output directory. These directories NEED TO BE THE SAME as the input and output directories that FinishLynx uses in order for the data to be transferred between Roster and Lynx (see below on the Lynx setup). 

TIP: the input and an output directory should be folders or sub-folders on a drive (e.g., C:) and you should avoid adding the folder directly to your desktop. 


Now let’s go to the FinishLynx setup before returning to load the configuration in Roster. Go to the FinishLynx program.


Open the Options menu under File in FinishLynx. 



Make sure the Input Directory and the Output Directory point to the exact same directories as you set up in the RosterAgent. Additionally, you need to make sure that Code set and LIF Code set are set to Unicode.

Please note: if the directories are not the same between Roster and Lynx, the data will not be transferred and you will not get the expected results. Please double-check these directories.



You will only need to change these settings the first time you set up the integration, after which they will come up by default.

Serial port

If you select Serial port as the integration type, then you will have to select the serial port.

It should look like this in the RosterAgent:


You will also need to change the corresponding settings in Lynx by setting the Data Source to Serial Port and Serial Port to the appropriate COM port in the Database tab under the File and Option menu in FinishLynx.


Please note: if you don't have a Serial port on your computer, see this link for a recommendation for a USB to Serial adapter.

Starting integration

1. Choose participants that you want to export from Roster Athletics to FinishLynx. You can find this setting on the meeting Details in the FinishLynx integration section.

You can export all participants or exclude participants with DNS status (e.g., when you already know before the competition that the athlete will not show up, but do not want to remove him/her).

2. In the same section below, choose the display format that will be visible and used within FinishLynx when viewing events.

There are 3 Event description format types to choose from. Events will be displayed in FinishLynx as follows:

  • Detailed format: event time, event name, gender (if more than one gender), age group (if more than one age group), event title (if a title is assigned), group/heat number (if they have been assigned).
  • Simple format: event name, gender (if more than one gender), age group (if more than one age group). group/heat number (if they have been assigned).
  • Custom format: allows you to choose your event format to be displayed within FinishLynx. 

The Custom format field allows you to pick the event descriptors and order to be displayed. Click on the descriptors of your choice to add them to the field. Erase by simply deleting them. Please note that the field format requires colons around each descriptor, and the descriptors must be separated by a single space. Thus :EventName: :Gender: would display only the event names and gender for each event in FinishLynx. The options are as follows:

  • Age group: always display the event age group
  • Age group opt.: display the event age group if only there is more than one age group in the meeting (Note: recommend to choose either Age group or Age group opt., but not both)
  • Combined prefix opt.: display the combined parent event if a combined event is used
  • Event label opt.: display the event title if one exists for the event
  • Event name: always display the event name
  • Gender: always display the event gender
  • Gender opt.: display the event gender only if only there is more than one gender in the meeting (Note: recommend to choose either Gender or Gender opt., but not both).
  • Group opt.: display the group/heat number only if they are used for the event
  • Stage: always display the event stage
  • Time: always display the event time

If you need to reset the Custom setting, press the Default symbol to return to the initial set of recommended default parameters.

3. Now you are ready to load and integrate your meeting data.


Go back to Roster Athletics in your browser.

Open the relevant meeting and go to DETAILS. On the left-hand-side, click the Agent config button.

This will download an authentication .roster file for your specific meeting that lets the RosterAgent know to use this meeting to connect with Lynx. Save the file in a place where you can easily find it again. 

Please note: It is critical that you use the LAST downloaded authentication file to load into the RosterAgent. Otherwise, the permissions will not match and you will not be able to connect to your meeting (“Can’t connect - permission denied”).


Once the authentication file is downloaded, go to the RosterAgent. Click on Load configuration and select the latest .roster file (e.g., meeting-xxx-auth.roster) for this meeting that you downloaded (as soon as you load the configuration, a ".roster" file will be saved. This file stores the directory information so you don't need to enter directory settings every time.).

Click Connect. Now FinishLynx and Roster Athletics are connected.


If you have Show notifications enabled by default, you will see status messages such as:


You can disable notifications by pressing the Show notifications button, which will then appear as a lighter shade button.

Once you have prepared your start lists in Roster Athletics, then go to FinishLynx. Click on the Select event icon and when you see the dialogue, then click on Load Schedule. When you have done so, click on the drop-down menu and select the event you want to time and click OK.


Now the synchronization setup is complete and the start lists for a particular event are loaded into FinishLynx. FinishLynx is now ready to go and the event can commence in standard FinishLynx procedure. Once the event has finished and FinishLynx has the results, click on the Save LIF under File and wait approximately 10 seconds or less while the data is synced to Roster Athletics.


Please note: if saving FinishLynx event .evn file including images, the order of operation should be:
  1. File Save LIF
  2. File Save as... (into the folder or networked folder to be shared)

Now you can go back to Roster Athletics and see the times and rankings for the athletes that have been updated from FinishLynx. The results are also immediately available in the Roster Athletics App.


Important note: every time you make an update to the start list in Roster Athletics, it is automatically pushed to the Roster Athletics Agent, but you still need to Load Schedule in FinishLynx to load these changes. Also, field events are not supported by the standard version of FinishLynx.

If you have a wind reading in FinishLynx, this information will be automatically transferred to Roster Athletics. 

BIB-numbers: If you have added BIB-numbers in Roster Athletics, you will find them under the field Id. If you have not added BIB-numbers, the Id field in FinishLynx will have an automatically generated athlete-ID.

OPTIONAL: If you want BIB-numbers in a different field, you need to enable an additional field in FinishLynx as follows: (i) Select User 1 under File → Options... → Results, (ii) select User 1 under Fields and (iii) click Enable. You will now be able to transfer BIB-numbers as shown below.

Reaction times: If enabled in FinishLynx, reaction times will be transferred back to Roster Athletics.

Competitor status: in FinishLynx, the status for each athlete can be set under Place  `right click`  Status. These status options translate to Roster in the following manner:

  • Valid OK
  • Did Not Start DNS
  • False Start DQ (+ selection of DQ rule)
  • Did Not Finish DNF
  • Scratched DNS
  • Disqualified DQ (+ selection of DQ rule)
  • Advanced →  is not used since qualifying Q/q rules are set in the Roster Schedule and qualification is handled entirely in Roster (either auto Q/q or manual q's)

DQ rules can be added in Roster but not directly from FinishLynx.

Troubleshooting Tips & Tricks

  • Make sure you are running the latest version of the RosterAgent (please see the Download and install RosterAgent for latest version number).
  • If a message of "Can't connect - permission denied" message pops up while trying to connect the RosterAgent, make you have loaded the latest version of the meeting agent configuration file. This file is downloaded from meeting Details  Agent config.
  • If you are using shared folders and your connection status is good but either a.) your start lists in Roster are not updating to Lynx or b.) your saved results in Lynx are not being updated to Roster, make sure you carefully check your paths on both the RosterAgent and FinishLynx (File → Options → Database) to see that both the set of input and output directories are pointing to the exact same location and that the settings described above for set-up (File → Options → Database) are all followed precisely.
