3.3.3 Setting TDMA Mode
The TDMA mode enables:
• Set TDMA frame type to either Open Road (default) or Lane Based.
• Internal Act, External Act: Enable/disable internal/external activation messages
from transponders.
• “F” EH: Set the extended header type: “1111…” or “10101…” (default).
• Sleep Time: Set the sleep interval used when commanding a transponder to “sleep”.
3.3.4 Setting Transponder Access Parameters
The transponder access parameters are as follows:
• Net Re-entry Delay: Set the time transponder activation messages are ignored after
transponder sleep command.
• Max Access Retries: Set the number of times the FP-300RA tries to access a
transponder before it is declared lost.
• Ping Function, Ping rate: Enable/disable the ping function and set the ping rate.
• Tag Lost Timeout: Set the number of frames in which transponder activation
messages have not been detected before a transponder declared lost. If the
transponder was previously accessed (either by ping, auto-function or a host
request), then the tag will be declared lost 10 seconds after the last access.
3.3.5 Setting Burst Mode
The primary use of the burst mode is during communication zone calibration. When the burst
mode is enabled, the FP-300RA will be in the normal Tx mode for the number of frames
selected by Frames ON and will then enter the mute Tx mode for the number of frames
selected by Frames OFF. To make sure that all the transponders will lose synchronization to
the FP-300RA, set Frames OFF to more than 15.
3.3.6 Setting SYNC Mode
The PF300RA SYNC mode can be set to None, Master or Slave, by click the corresponding radio
button. The default SYNC pulse timing values are set according to field tests.
If required, the SYNC pulse timing can be adjusted as explained below.
• SYNC Slave Mode: in this mode, you can adjust the delay between the falling edge
of the SYNC pulse and the start of a new frame, designated SYNC to FCM, can be
adjusted in the range of 800 ±15 µsec.
