Chapter 7: I/O Device
The CamSS system can control an external I/O device. The I/O devices can generally be divided into three
categories as follows:
1. Computer ISA Interface I/O card. This is used to detect the On/Off state of the input point, or control the
ON/OFF state of the output point. It also can be used to control the traditional PTZ.
2. RS232-to-RS485 interface I/O control device. It functions the same as the above.
3. RS232-to-RS485 interface (high speed) dome camera control. Its operation is divided into two parts,
namely I/O Control and Camera PTZ control.
7.1 I/O Device Setup
The I/O Device Setup button may be found on the System pull-down menu in the
System Operation Section .
Click the button and enter into the I/O Device Setup screen:
Selecting the desired I/O device:
First, decide which I/O device type is needed. I/O devices are categorized by connection ports into two types,
i.e. ISA interface and RS232 (COM Port)-to-RS485 interfaces.
Devices supporting ISA Interface
CH-8I8O: (8 voltage inputs and 8 relay outputs)
To set the address of the I/O devices, follow the operations guide regarding adjusting the DIP switches
on the I/O cards. The system default value is I/O port 0x300 (in hexadecimal address). The default
address is “OFF OFF ON ON ON ON ON ON”.
