5、ous display of up to 4 VBOX data values. Values are user selectable and are shown in table 1 (Page 6). Thirteen pages exist within the display memory. The first two pages contain a total of 8 parameters. Any of the VBOX data values can be assigned to a parameter. The third page indicates GPS positio

6、n as latitude and longitude. The fourth page takes the form of a target bar graph. The parameter and the target value are selected by the user allowing the user to attain consistency during test procedures. The fifth screen is for circuit laps. Target screen and circuit lap screen have their own sub

7、 menus, main screen 1 & 2 and Lat/Long share a sub menu. The last eight screens are Pre-set Test screens to allow the pre setting of eight different test profiles, which can then be quickly swapped between. Ideally suited for the quick test environment of Magazine test schedules.多功能显示器能够同时显示 4 个

8、 VBox 的数据值。如同表 1（第 6 页）一样，用户可以自己选择需要显示的数值。显存中一共包含 13 个页面。第一、二页一共有 8个参数。可以将 VBox 的任意一个数据值分配给一个参数。第三页显示了现在的GPS 位置，如经度和纬度。第四页是目标数据的柱状图。参数及目标数值是由用户选定的，用户可以在测试过程中获得连续数据。第五页是专门为跑道而设的。目标数据页面及跑道页面有它们各自的子菜单，主页面 1 和 2 及经纬度共用一个子菜单。最后的八页是预设置页面，允许用户预先设置八个不同的测试档案，这样用户可以快速切换调用这些文件。这尤其适用于类似于杂志测试的快速测试环境。Connection t

The parameters are split into 4 groups, General parameters, Brake parameters, Accel parameters and CAN parameters. The General parameters are taken from raw CAN data

21、from the VBOX. The Brake parameters are parameters used in brake testing. The majority of which require the use of a brake trigger switch with the VBOX. The Accel parameters are parameters used in acceleration tests. The CAN parameters are from external modules connected to the CAN bus, such as anal

22、ogue, thermocouple and vehicle CAN data.表 1（第 8 页）中列出了所有的参数代码。参数被分成了 4 组，综合参数，制动参数，加速参数和 CAN 参数。综合参数是从 VBox 传来的未经处理的数据中得到的。减速参数是用于减速测试的参数。其中绝大部分都要使用到 VBox 的减速触发开关。加速参数是用于加速测试的参数。CAN 参数是从连接到 CAN 总线的外部模块，如模拟、热电偶及车联 CAN 数据，得到的。Display Parameters (Table 1)/显示参数（表显示参数（表 1）Parameter type参数形式Parameter code
