Figure 5-4. System Configuration Window
The System Configuration window contains the following sections and associated data fields:
• “LF Antennas” – This section includes controls used to select the antenna channel, the current and associated
vehicle ID.
– “Antenna Channel” – Selecting any of these radio buttons assigns which antenna channel is used to send
the LF message from the vehicle. The Ant connector number on the board starts at Ant0 while the antenna
channel displayed on the CARS PC application starts with antenna channel 1. As a result, antenna channel
1 on the PC application corresponds with Ant0 on the board. This offset count continues for all six antenna
channels.
Notes:
• When using the ATA5291-XPRO and antenna channel 1, ensure that the J1 jumper on the LF antenna
module is set to the inductor only (
) position. When channels 2 through 6 are used, ensure the
J1 jumper on the LF antenna module is set to the LCR option.
• When using the ATA5293-XPRO and antenna channel 1, the X-10013-002 antenna is required. When
antenna channels 2 through 5 are used, the X-10013-003 antenna is required; channel 6 is not used
within the PC application.
– “Antenna Current” – This drop-down list determines the amount of current flowing in the LF antenna
during the LF message. This is directly related to the field strength at a given distance from the antenna.
Therefore, any change to this value has a direct impact on the performance of the localization during
PEPS.
– “Vehicle ID” – Sets the wake-up value transmitted with the LF message. Only fobs that are looking for
this value wake up and respond. The vehicle ID is set in the fob during the learn procedure and is
user-definable.
• “Learned Fobs” – This section lists up to four individual fob IDs paired with the system and saved in memory.
