Description

perf_en

Performance test. Default value = 0

can1

See CAN_SETTINGS structure

canfd1

See CANFD_SETTINGS structure

can2

See CAN_SETTINGS structure

canfd2

See CANFD_SETTINGS structure

network_enables

Bitfield containing the software license enables. To enable a specific network its corresponding bit must be set (1). In order to transmit or receive on a network it must be enabled.

HSCAN : Bit 0

HSCAN2 : Bit 5

termination_enables

Bitfield containing the enables for CAN Termination. To enable a specific channel its corresponding bit must be set (1). .

HSCAN : Bit 0

HSCAN2 : Bit 5

pwr_man_timeout

Number of milliseconds of no bus activity required before neoVI enters low power mode. Note pwr_man_enable must be set for power management to be enabled.

Default value = 10000

pwr_man_enable

1 = enable Power Management, 0 = disable.

Default value = 0

network_enabled_on_boot

Normally neoVI only initiates its comm channels when CoreMini is running or if neoVI is online with DLL/Vehicle Spy 3. Practically this means the the CAN controllers stay in Listen Only mode until the device goes online. Once online the neoVI loads the user settings. Setting this parameter to 1 will change this behavior so that the neoVI enables its controllers immediately on boot.

Default value = 0

iso15765_separation_time_offset

In an ISO15765-2 Transmission, the receiver transmits a flow control message that informs that transmitter how much time there should be between individual CAN messages. This parameter allows the user to shift that spacing to make it smaller or larger. Valid range is -1563 to 1563 units where each unit represents 6.4us. Defaults to 0. If IFS plus the offset is negative than the Tx Messages will be back to back.

Default value = 0

Examples:

ISO15765-2 Tx Message Inner frame spacing is exactly what is specified in flow control message: iso15765_separation_time_offset = 0

ISO15765-2 Tx Message Inner frame spacing is what's specified in flow control message.+ 998.4 us: iso15765_separation_time_offset = 156

ISO15765-2 Tx Message Inner frame spacing is what's specified in flow control message.- 998.4 us:
iso15765_separation_time_offset = -156

text_api

See STextAPISettings structure

flags

Bitfield with misc settings for the device. List below gives the parameter with the bit number to have set to enable.

Disable USB Check On Boot : 0
