RaceAmerica 5840 T-Link 3.0 Wireless

TECHNICAL DETAILS

Connection to a PC or Timer:

The output of the 4520UIDZ USB Wireless 

unit has the following:.

Data String Protocol:

Data strings are sent from the 4520UIDZ 

unit to provide timing timestamps from each 

track sensor, battery charge level in each T-Link 

3.0 unit, and RF Data Integrity level of the 

wireless communications between the T-Link 

3.0 units.  The data strings are always terminated 

by a ‘carriage return’ (cr) character and are 11 

characters in total length.

<id> is the ID code of the T-Link 3.0 - A thru G  

 

are valid

<timestamp> is a 9-digit number for timing use

<error code> is a single digit number explained

 

under Error Codes

<rev level> is a 3-digit number of the Revision

 

Code of the T-Link 3.0

<batA> is a single digit number of the Battery

 

Charge Level of a T-Link 3.0 unit

<rfA> is a single digit number of the RF

 

Integrity Level of a T-Link 3.0 unit

<id> <timestamp> cr

ZB <bA><bB><bC><bD><bE><bF><bG><bZ> cr

ZW <rA><rB><rC><rD><rE><rF><rG> 0 cr

<id> E <error code> 0000000 cr

<id> R <rev level> 00000 cr

 

Error Codes:

When a condition occurs interrupting normal 

T-Link 3.0 operation, an error message is sent by 

the 4520UIDZ unit.  T-Link 3.0 are self-correcting 

devices and can with stand continuous interruption 

of up to 10 seconds with 100% timing accuracy.  

The error codes are sent in the format of:

<id> E <error code> 0000000

(example: AE3000000)

E1 - Bad trigger data on ID B, C, D, E, F or G

E2 - Greater than 10 sec since last good data

 

received from ID B, C, D, E, F or G

E3 - Nothing received from ID A during the

 

last request

E4 - Greater than 10 sec since last good data 

 

received from ID A

E5 - Math overflow during calculation on

 

ID B, C, D, E, F or G

All error messages are realtime during 

normal operation with different levels of urgency.  

Errors E1, E3, and E5 indicate local interference 

effecting the wireless communications or loss of 

signal.  These are error messages to alert the user 

of intermittent interference and do not effect the 

accuracy of the timing system unless the error codes 

continue for more than 10 seconds of operation.  

Errors E2 and E4 also indicate local interference 

effecting the wireless communications or loss of 

signal unless these error codes are preceded by 10 

seconds of continuous error codes.

   

  

MAINTENANCE

  To insure uninterrupted operation on race day, 

it is suggested to keep track of battery usage hours 

so as to have fully charged batteries.   To maintain 

the highest level of timing accuracy and minimize 

false trips, annual preventive maintenance and 

calibration should be performed on all system track 

sensors and beam emitter units.

SPARE PARTS

  Further to minimize race program interruptions, 

RaceAmerica recommends some spare parts.  A 

spare emitter/sensor pair should be available in the 

event of an unfortunate accident during a program.  

Contact RaceAmerica for availability and pricing 

of spares items.
