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.

Enhanced Serial Interface Module for Excalibur 8000 Family of Carrier Boards, with High Baud Rate & High Throughput
M8KSerial
The M8KSerial is an enhanced serial interface module for the multiprotocol Excalibur 8000 family of carrier boards, that includes several advanced features such as a high baud rate and high throughput. This module supports up to two independent channels of serial communications, each of which can be selected as RS-485, RS-422 or RS-232. The module operates independently of the host computer, reducing the need for host intervention.The M8KSerial module is based on the Exar XR16M570 Universal Asynchronous Receiver/Transmitter (UART). The device is compatible to industry standard 16550 UARTs. Each of the M4KSerialPlus’s four channels contains a transmit FIFO capable of holding up to 16384 bytes and a receive FIFO capable of holding either 16384 receive bytes or 5460 bytes with a 32-bit Time Tag associated with each byte. These large buffers allow application code to transfer large quantities of data with a single non-blocking subroutine call. The 32-bit Time Tag on receive channels is very useful for synchronizing serial data with data from other modules on the 8000 board or on other interface boards. Each channel has a programmable baud rate of up to 10 Mbps and can be configured as RS-232, RS-422 or RS-485.The M8KSerial module is supplied with C drivers, including source code.
