Remarks

Item	Description
icscm_uint8 Mode	CAN controller mode when the neoVI device goes online or runs a CoreMini script. Default value = 0 NORMAL 0 DISABLED 1 LISTEN ONLY 3 LISTEN ALL 7

LISTEN ALL	7
icscm_uint8 SetBaudrate	The bit rate of a CAN channel can be selected one of two ways. It can either be selected from a list of common bit rates (SetBaudrate=1) or the user can specify the CAN timing parameters (SetBaudrate=0) AUTO (Select from bitrate list using Baudrate parameter) 0 USE_TQ (Use time quanta parameters 1
AUTO (Select from bitrate list using Baudrate parameter)	0
USE_TQ (Use time quanta parameters	1
AUTO (Select from bitrate list using Baudrate parameter)	0
USE_TQ (Use time quanta parameters	1
icscm_uint8 Baudrate	The bit rate of a CAN channel can be selected from a list of common bit rates Write the correct enumeration for the desired bit rate and ensure that SetBaudrate is 1(auto) Default value = 8 Note: This parameter is only applicable if SetBaudrate = 1 20000 0 33333 1 50000 2 62500 3 83333 4 100000 5 125000 6 250000 7 500000 8 800000 9 1000000 10

icscm_uint8 NetworkType	Currently Not used. Will be supoprted in neoVI Yellow to software select which CAN transceiver to use (DW vs SW vs LSFT).
icscm_uint8 TqSeg1	Phase 1 segment
icscm_uint8 TqSeg2	Phase 2 segment
icscm_uint8 TqProp	Propagation delay
icscm_uint8 TqSync	Syncro jump width

icscm_uint16 auto_baud	Enables the auto bitrate feature. 1 = enable, 0 = disable. Default value = 0
