Ethernet To Serial Converters

Introduction: I-7188EN: Can be used as Ethernet to RS-232/485/422 Device Server. The device server is an appliance that network enables any device with a serial communication port. By virtue of its independent operating system, protocol independence, small size and flexibility, sevice servers are able to meet the demand of virtually any network-enable application. Most devices don’t have network ports. Our internet communication controllers allow those devices to become connected to the network. It can be used as embedded internet/ethernet controller except the real time clock, the hardware and software of I-7188EN is similar to I-7188EX. The user can use well-developed libraries and demo. Features: • Built-in self-tuner ASIC controller on RS-485 port • I-7188E1 support one RS-232 port • I-7188E2 support one RS-232 port and one RS-485 port • I-7188E3 support one RS-232 port, one RS-485 port, one RS-422/485 port and several DI/O lines • I-7188E3-232 two RS-232 ports, one RS-485 port and several DI/O lines • I-7188E4 support three RS-232 ports and one RS-485 port • I-7188E5 support four RS-232 ports and one RS-485 port • I-7188E5-485 support one RS-232 ports and four RS-485 ports • I-7188E8 support seven RS-232 ports and one RS-485 port • 7-segment LED display for I-7188 EnD (n=1,2,3,4,5,8) • Built-in MiniOS7 • Program download port: COM1 or Ethernet Port (Available soon) • Dimensions: 123mm x 72mm x 33mm • Power requirement: Unregulated 10~30 VDC with protection from power reversals • Power consumption: 2W (without display) 3W (with display) Add to Enquiry Basket

USB To RS232/422/485 Converters

The I-7561 is a cost-effective module for transfer serial data over USB. It allows you to connect your serial devices to systems using a USB interface. Connecting the I-7561 to a PC, you get one or two extra high-speed RS-232/422/485 ports. Like our I-7520A, the I-7561 contains "Self Tuner". This chip auto-tunes the baud rate and data format to the Rs-485 network. The I-7561 module derives the power from the USB port and doesn’t need any power adapter. It also features a high-speed 115.2 Kb/s transmission rate, and supports various O.S. independent RS-232/422/485 ports.

RS485 /RS 422 Repeaters & RS232 Isolators

Communication Converters change one type of signal (typically RS-232 or USB) into another more robust or more transportable signal (typically RS-422, RS-485 or Ethernet). RS-422 communication links are used where distance, electrical noise or lack of speed would make RS-232 unsuitable. RS-485 has all the advantages of RS-422 as well as multi-dropping and half-duplex operation. Use of a Serial to Ethernet converter allows extra COM ports to be added remotely to a PC via a network. Features • Input: RS-232, RS 422, RS 485 protocol • Output: RS-232, RS 422, RS-485 protocol • Speed: Self Tuner inside, auto switching baud rate, 300~115200 BPS • 256 modules max. in one RS-485 network • 2048 modules max. in one RS-485 network • Isolation voltage: 3000VDC • Repeater request: 4,000 feet or over 256 modules • Power consumption: 2.2W max. I 7510/ I 7510AR model is used for PLC user. The design of isolation between Any RS 232, RS 422 & RS 485 Network. If the user want to supply the power from PLC, he should use the I 75XXR. Otherwise the isolation will be broken. For Supply from PC side Use I 75XX. Add to Enquiry Basket
