Inst alling Software and Configura tion Tools
The first step to using the API, is installing the needed drivers and dlls. T his can be done in a few different ways. Installing Vehicle Spy 3 (full and free version) or the API install kit found
on the CD that shipped with t he hardware will take care of this step. Software can also be found on support page of Intrepid Control Syst ems Website.
From the CD that shipped with t he unit, run the icsAutoPlay.exe from the root of the disc (if it does not start automatically). This will give you the option of installing Vehicle Spy 3 or t he
API install kit. From the Website, the following links will have t he latest software.
-Vehicle Spy 3 Trial includes everything in the API install kit and has Vehicle Spy 3 Trial.
-API install kit for RP1210, J2534, and Intrepid Controls Systems' API.
Inst alling the neoVI dev ice on USB
Next, verify that you have the following minimum system requirement s:
One free USB port
Windows XP (SP3), Vista, 7, 8, 8.1, or 10 (Windows RT is not supported)

Firs t, you ca n set the bit rate of the SCP network (figure 1 : bubble 1). The standard network bit rate is 41.6 kbps. The higher speed 83.3 kbps is sometimes used on the network for special network operations. Special Monitor mode only supports the 41.6 kbps rate.
The OBD connector used in neoVI connects the J1850 VPW network to the J1850 + line. neoVI contains a relay the can switch the JPWM + si gnal on to that line instead of JVPW. This allows you to use one connector with both protocols. You can have neoVI default to
either connecting VPW (default) or PWM (Figure 1: bubble 2). You can control the relay at run time using a neoVI virtual network can message.
You can set the Node Address of the Ford SCP node. This is shown in the figure 1: bubble 3. This is used for setting the source id and is used when the LBCC generates In frame responses (IFRs). This address must be unique for each node on the SCP network.
Next, you can set the Network Driver and Receive Control Register (NDRC) of the LBCC. This is shown in figure 1 bubble 4. The NDRC is a register in the LBCC which allows you to transmit o r rece ive on p orti on s of the d ua l wire n etwork. Norm a lly, thes e

Special Monitor mode allows you to monitor all traffic on the SCP network. To enable this node click the check box in figure 1 bubble 6. This enables special firmware in neoVI that monitors and decodes the raw SCP waveform. When this is done, both J1850 VPW and
ISO/KW2k protocols are disabled. You can still use the Ford LBCC channel. All monitor mode messages come across on the J1850VPW network.
