RS-232/422/485 to Fiber Optic Converter Introduction The I-2541 is an RS-232/422/485 to fiber optic converter that secures data transmission by using fiber optic transmission to provide immunity from EMI/RFI interference. The I-2541 is used for RS-232/422 point-to- point connections and RS-485 multi-drop applications for transmitting a signal up to 2 Km(6,600 ft), and is the perfect solution for applications where transmission must be protected from electrical exposure, surges, lightning or chemical corrosion.

Industrial 10/100 Base-T to 100 Base-FT Fiber Optical Converter Introduction The NS-200FT is a Ethernet(10/100Base-TX) to Fiber Optic(100Base-FX) converter. The Ethernet supports 10/100M auto-negotiation feature and auto MDI/MDIX function. The NS-200FT operates at either half or full duplex mode. In full duplex mode, range is 2km with 62.5/ 125£gm fiber cables; in half duplex mode, range is 412m with 62.5/ 125£gm fiber cables. It contains "soft start" function with overload protection, high-low voltage protection. The width of the NS-200FT is just 32.30 mm, so it can be used where space is important. Features Automatic MDI / MDI-X crossover for plug-and-play Each port supports both 10/100 Mbps speed auto negotiation Store-and-forward architecture Full duplex IEEE 802.3x and half duplex backpressure flow control 1.4Gbps high performance memory bandwidth. Integrated look-up engine with dedicated 1 K unicast MAC addresses. MTBF = 438,000 hours( Temperature is 25 ¢X) MTBCF = 525,600 hours ( Temperature is 25 ¢X) Supports +10~+30Vdc voltage Supports operating temperatures from 0 ~ +70¢XC DIN rail mount for industrial usage

Wireless Modem Module RS-232/RS-485 Interface Introduction SST-2450EXT is a spread spectrum radio modem with RS-232/RS-485 interface port. It is designed for data acquisition and control application between host and remote sensors. It is also useful for those applications, the cable wire is inconvenient to be installed. The SST-2450 can be used in not only peer to peer mode but also multi-point structure. Based on direct sequence spread spectrum and RF technology operating In ISM bands. The Frequency Range is 2410.496MHz~2471.936MHz. The Channel Spacing is 4.096MHz. Basically the SST-2450 is the same with SST-2400. The most different is the setting method. SST-2400 is set by jumper, and the SST-2450 is set by software utility. The new SST-2450 can also work together with this SST-2400 if you change the inside 8051 chip of SST-2400. Just contact us, then we will ship a new chip which is with a new firmware.
