RS232 / RS485 / RS422 / Serial To Multi-Drop Fiber Optic Converters
-
Our advanced, rugged, industrial-grade, RS232 / RS485 / RS422 serial to multi-drop fiber optic converters are designed to cover large areas. These converters support up to 255 fiber nodes, and each fiber node can extend the RS232 / RS422 / RS485's distance to 3 miles (5km) for multi-mode converters and cables, or 25 miles (40km) for single-mode converters and cables. Depending on the site situation, these multi-drop fiber optic converters can be configured as a daisy-chain or a self-healing redundant ring fiber network. When configured as a ring fiber network, the built-in self-healing feature allows the data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same fiber ring, making the entire data network more robust and reliable. These multi-drop fiber optic converters have been designed for harsh industrial environments and withstand a wide temperature of -40°F to 185°F (-40°C to 85°C), and they come with the options of multi-mode and single-mode, and ST, SC, and FC connectors.

Compact Protocol Analyzer
LE-1500R
-
"LE-1500R" is a protocol analyzer (line monitor) dedicated for asynchronous communication monitoring with affordable pricing. LE-1500R can run as a stand- alone by the internal battery for long time and can be remotely controled by a PC or a smart phone via Wi-Fi (Wi-Fi function is available only in USA, Canada, Japan, and EU). The analyzer has a TTL measurement port (which supports UART communication) as its standard port besides RS-232C, RS-422, and RS-485. It can monitor communication data of max 500Kbps for up to 32MB (8,000,000 data) in real time and also can execute a simulation testing of send/receive data. It also has a BERT function (which is not equipped with the analyzers of this pricing level) as its standard function. The correct time stamp, the measurement of idel time (which are the difficult for other software analyzers), and the capturing ability (without missing data) are the best options for trouble shooting and development test of a communication sytem which requires a reliablity.

Mezzanine System
5033
System
ECM P/N 5033 provides eight channels of RS485 / RS422 I/O. The 110 ohm termination for each channel is enabled or disabled in software. Disabling termination saves power by eliminating unneeded or redundant termination. Speeds of up to 20 Mega bits per second are possible, but this design also features a 250K bits per second slower edge rate mode. The 250K bit mode is valuable when EMI is more of a concern and throughput is not important. All channels power up as inputs with the outputs disabled.
