Introduction There are many RS-232 devices in industry applications. Nowadays it becomes important to link all those RS-232 devices together for automation & information. Usually those RS-232 devices are far away from the host-PC & widely distributed in the factory. So it is not a good idea to use multi-serial cards to connect all these RS-232 devices together. Our I-752x series products can be used to link multiple RS-232 devices by single RS-485 network. The RS-485 is famous for it’s easy maintenance, simple cabling, stable, reliable and low cost. When the user want to connect RS-232 devices to 10BASE T, our I-7188EN can meet this demand. Refer to I-7188EN literatures for further information. Onboard 1K bytes Queue-buffer The I-752X equips 1K bytes queue-buffer for its local RS-232 device. So all input data can be stored in queue-buffer until the host-PC has time to read. These features will make the host-PC link thousands of RS-232 devices without lose any data. Onboard D/I for event trigger The I-7521 and I-7522 equip three digital input channels, while I-7523 equips two digital input channel for sensor interface. These D/I can be used to link with photo sensor/switch for event trigger. They also can be used as general purpose D/I. The 752X can read & analyze these D/I without the help of host-PC. Onboard D/O for emergency control The I-7521 equips three digital output channels, while I-7522 equips one digital output channel for emergency control. The D/O can directly drive relay or led. They can be used to control the local devices for emergency event. The 752x can control these D/O without the help of host-PC. 3000V isolation on RS-485 site The COM2 of the I-7521/22/23 is an isolated RS-485 port with 3000V isolation. This isolation will protect the local RS-232 devices from transient noises coming from RS-485 network. Self-Tuner ASIC inside The I-752X equips a Self-Tuner ASIC for RS-485 port. This chip can auto detect and control the send/receive direction of the RS-485 network. Therefore the application programs don’t have to take care of the direction control of the RS-485 network. The advanced technology which makes this possible is covered by R.O.C. Patent 103060, 132457. Can used as Addressable RS-485 to RS-232 Converter Most RS-232 devices don’t support device address. The I-752X series can assign a unique address to any RS-232 device installed in the RS-485 network. Host-PC can send command with device address to RS-485 network, the destination-752x will remove the address field & pass the other fields of command to its local RS-232 device. The response of this local RS-232 device will be passed to host-PC via this destionation-752x. Master-type Addressable RS-485 to RS-232 Converter Basically our 752X products are Master-type converters. The 752X use our R.O.C. Patent 086674. Other competitor’s converter is Slave-type and can’t work stand alone without host-PC. In real industrial application, the demand is different case by case and customers are not satisfied with Slave-type. The 752x are very powerful and can analyze the local RS-232 device, D/I or D/O without host-PC. Refer to Application 5 to Application 9 for more information. Can be used as an Embedded Controller Besides Intelligent Communication Controller, the I-752X series products can be used as an embedded controller. Every I-752X controller has an, MiniOS7, embedded O.S. . The MiniOS7 provides equivalent functions of ROM DOS and has more features. The user can use well-developed libraries and demo programs to implement his controller. Can be used as RS-485 to RS-232 Device Server The Device Server is an appliance that network enables any device with a serial communication port. Our Intelligent Communication Controllers allow those devices to become connected to the RS-485 network If the user want to use Ethernet work, he can choose I-7188EN series products.

These D/I can be used to link with photo sensor/switch for event trigger. They also can be used as general purpose D/I. The 752X can read & analyze these D/I without the help of host-PC. Onboard D/O for emergency control The I-7521 equips three digital output channels, while I-7522 equips one digital output channel for emergency control. The D/O can directly drive relay or led. They can be used to control the local devices for emergency event. The 752x can control these D/O without the help of host-PC. 3000V isolation on RS-485 site The COM2 of the I-7521/22/23 is an isolated RS-485 port with 3000V isolation. This isolation will protect the local RS-232 devices from transient noises coming from RS-485 network. Self-Tuner ASIC inside The I-752X equips a Self-Tuner ASIC for RS-485 port. This chip can auto detect and control the send/receive direction of the RS-485 network. Therefore the application programs don’t have to take care of the direction control of the RS-485 network. The advanced technology which makes this possible is covered by R.O.C. Patent 103060, 132457. Can used as Addressable RS-485 to RS-232 Converter Most RS-232 devices don’t support device address. The I-752X series can assign a unique address to any RS-232 device installed in the RS-485 network. Host-PC can send command with device address to RS-485 network, the destination-752x will remove the address field & pass the other fields of command to its local RS-232 device. The response of this local RS-232 device will be passed to host-PC via this destionation-752x. Master-type Addressable RS-485 to RS-232 Converter Basically our 752X products are Master-type converters. The 752X use our R.O.C. Patent 086674. Other competitor’s converter is Slave-type and can’t work stand alone without host-PC. In real industrial application, the demand is different case by case and customers are not satisfied with Slave-type. The 752x are very powerful and can analyze the local RS-232 device, D/I or D/O without host-PC. Refer to Application 5 to Application 9 for more information. Can be used as an Embedded Controller Besides Intelligent Communication Controller, the I-752X series products can be used as an embedded controller. Every I-752X controller has an, MiniOS7, embedded O.S. . The MiniOS7 provides equivalent functions of ROM DOS and has more features. The user can use well-developed libraries and demo programs to implement his controller. Can be used as RS-485 to RS-232 Device Server The Device Server is an appliance that network enables any device with a serial communication port. Our Intelligent Communication Controllers allow those devices to become connected to the RS-485 network If the user want to use Ethernet work, he can choose I-7188EN series products.
