CRS2F Series

Point System™ RS232 Remotely Managed Media Converter Module
RS232 Copper to Fiber

The CRS2F Series stand-alone serial RS232 to fiber converters allow you to extend the distance between serial connections with the use of fiber optic cable. These full-featured stand-alone media converters transmit the full complement of RS232 flow control/handshaking signals optically and supports full or half-duplex asynchronous data transmission at speeds up to 115 Kbps. Link a remote terminal to a host computer: Connect multiple devices, such as security scanners, POS devices, remote terminals and building access/alarming systems to a host computer. Ideal for campus or business environments where remote devices can be networked in a point-to-point configuration where distances are greater than the 15 meter limitation of conventional copper serial cables.

Please note: this product is soon to be retired and replaced by the ION Platform. Limited quantities may still be available, contact our sales team to find out more. For more information, view the Point System vs ION product comparison and cross reference guide.
