7.1.1 Selecting the desired I/O device

 RS232/RS485 interface I/O device:

We support PT811 input device. 8 ON/OFF inputs, 8 digital output

modules; address range: 0x01-0xFF. PT811’s address shall be set

before the delivery of goods is made; otherwise you shall seek the

manufacturer for required hardware and software support. Each

PT-811’s address must be different from that of any other PT-811

on the same COM port to avoid error in control. Allow connection of

32 external I/O modules within distance of 1.2 kilometer. Depend on

the loading situation, the connecting distance and numbers will be

different.

 Speed Dome Camera:

This system can simultaneously control up to 16 dome cameras.

Since a control command is sent out by signals of RS-485

interfaces to all cameras, a camera shall adjust its address in order

to identify whether it can receive the command. Therefore, you

must remember a camera’s address and its setup location so as to

make a correct setting and avoid any error in control. The camera

brands that we support are as follow.

- DynaColor CA720 speed dome camera

- Lilin PIH717X speed dome camera

- Pelco-D or Pelco-P dome speed dome camera
