Thumbwheel
The thumbwheel provides an analog user input.It may be used for many functions such as calibration,scrolling through a list of sensor readings or controlling the speed of a motor.Depending on its position,the thumbwheel will return a value between 0 and 1023 when your program samples it.
Main Board Servo Ports
The IntelliBrain main board has two servo ports for hobby servos (see Figure 7 -Ports and Pin Arrangement).These ports may be used to control positioning servos or servos modified for continuous rotation.The ports support Futuba compatible servos with a 1 to 2 ms pulse control signal (1.5 ms center position).
The servo power and control lines are routed across the expansion header to provide additional powering options and additional servo ports when the expansion board is installed.When the expansion board is not present,three jumpers must be inserted between pins 1-2,5-6,and 7-8 on the expansion connector,as shown in Figure 12 - Expansion Board Connector Pin Out.
Attach your servos to the main board by plugging them into the servo port as shown in Figure 6 - Typical Sensor / Effector Connection.
The servo ports are powered directly from the main battery or DC power supply when the expansion board is not present.YOU MUST ENSURE THE BATTERY AND / OR POWER SUPPLY VOLTAGE DOES NOT EXCEED THE MAXIMUM SPECIFIED FOR YOUR SERVOS.See the main board power section for more information on powering when not using an expansion board.See the expansion board power section for more information on powering servos when the expansion board is present.
The main board servo ports are fused through a single 1 amp automatic resetting fuse.
Serial / CMUcam Port (COM2)
The COM2 port (see Figure 7 - Ports and Pin Arrangement) is an RS232 serial port.(Note:The COM2 port uses RS232 signal levels,not TTL signal levels).In addition to transmit,receive and ground pins,the port also provides a regulated+6V power supply with a 1 amp automatic resetting fuse to power the CMUcamor CMUcam2.
For information on using the CMUcam or CMUcam2 with the IntelliBrain controller see the RidgeSoft application note titled Vision Sensing with the CMUcam.
In addition to the CMUcam,the COM2 port can be used to interface with other devices that provide an RS232 interface,such as a Global Positioning System (GPS) receiver.Figure 9 shows how to construct an adapter cable to connect to a device that is designed to connect to a standard 9 pin COM port on a PC.Table 4 lists the parts and tool required to attach the 4 pin connector to the cable shown in Figure 9.In addition,you will need to solder the wires to the DB9 connector.

刚刚弄好,你看一下.
拇指轮
拇指轮提供了模拟用户输入,可用于多种用途,比如刻度校准,浏览传感器读数表单或是控制机器的速度.根据自身定位,在程序取样时,拇指轮会返回一个0到1023的值.
主板伺服端口
IntelliBrain为业余伺服系统准备了两个伺服端口（见表7－端口与插脚排列）.这些端口可以用来控制定位伺服系统或是为实现连续旋转而修改过的伺服系统.经过1到2微秒（1.5微秒中间位置）的脉冲控制信号,这些端口可以支持Futuba兼容伺服系统.安装了扩展板后,伺服系统的电源和控制线路会在扩展头设置路径,以便提供额外的电源选项和伺服端口.没有扩展板的时候,必须在插脚1-2,5-6,7-8之间插入3根跳线,如表12所示－扩展板连接器外围插脚.
用“表6－经典感应器/受动器连接”所示的方法把伺服装在主板上,插在伺服端口即可.
没有扩展板的时候,伺服端口直接从主电池或是DC电源获得供电.必须保证电池或是电源电压不超过伺服指定的最大电压.不用扩展板的时候,看看主板电源部分,以便获得有关供电的更多的信息.用扩展板的时候,看看扩展板的电源部分,以便获得更多给伺服供电的信息.
主板伺服的各端口通过一个单一的1安培的自动重置熔断器实现融和.
Serial / CMUcam 端口（COM2)
COM2端口（请看表7－端口和插脚排列）是一个RS232序列端口.（注意：COM2端口用的是RS232信号电平,而不是TTL信号电平）除了传输,接受和使插脚接地,为了给CMUcam或CMUcam2供电,该端口还提供一个带有1安培自动重置熔断器的＋6伏调节供电系统.
欲获得更多通过InteliBrain控制器来使用CMUcam 或CMUcam2的信息,请查阅标题为“CMUcam的视觉感受”的Ridgesoft的应用软件说明.除了CMUcam,COM2端口也可以用于与其他提供RS232接口的设备连接,比如全球定位系统（GPS）接收器.表9显示了怎样做一个适配器电缆来连接一个与PC上的标准9插脚COM端口连接的设备.表4列出了把4个插脚连接器连到表9所示电缆上所需的部件与工具.另外,你得把线焊到DB9连接器上.
