Console Servers / Data center management

Perle's IOLAN Console Server, sometimes referred to as a serial terminal server, provides data center managers what they need most - secure remote management of routers, switches, firewalls, servers (Solaris, Windows, Unix and Linux), PBXs or any device with a serial console port. Give your IT professionals and network operations center (NOC) personnel the only serial console server product on the market with all of the advanced security functionality needed to easily perform secure remote data center management and out-of-band management of IT assets from anywhere in the world. And, to make your choice easy, Perle IOLAN Console Servers have advanced functionality across the range.


Device Servers 

Perle’s IOLAN Serial Device Servers easily web or network enables existing equipment with RS232, RS422 or RS485 serial interfaces, quickly and easily.  These advanced Serial Device Servers are the best choice for connecting async devices such as modems, POS, printers and industrial equipment to serial based COM port, UDP or TCP socket based applications.


Terminal Servers

Perle’s IOLAN Terminal Servers easily connect any device with serial ports over Ethernet for access to network server applications. And, with innovative TrueSerial® technology, a Perle Terminal Server is the only product to guarantee authentic serial communications. These advanced serial to Ethernet solutions are your best choice for networking async devices such as Cisco console ports, POS terminals, servers, modems, card readers and a wide range of industrial equipment to TCP/IP Ethernet.


Fiber Media Converters

Perle's advanced media converters transparently connect copper to fiber, multimode to single mode and multimode to multimode fiber.  Media converters provide an economical path to extend the distance of an existing network, the life of non-fiber based equipment, or the distance between two devices.  With a broad choice of full-featured Fiber Media Converters, Perle has the right Unmanaged or Managed Media Converter to meet the needs of your fiber integration project.


Ethernet Copper Extenders

When you need to extend Ethernet services beyond the general IEEE 802.3 limits of 328ft / 100m, and new fiber cabling is cost prohibitive, Ethernet Extenders are the perfect solution. Perle Ethernet Extenders transparently extend 10/100/1000 Ethernet connections across copper wiring. Use single twisted pair ( CAT5/6/7 ), coax or any existing copper wiring previously used in alarm circuits, E1/T1 circuits, RS-232, RS-422, RS-485, CCTV and CATV applications.


Industrial Ethernet Switches

Perle Industrial-grade Ethernet Switches stand up to extreme temperatures, vibrations, and shocks found in industrial automation, government, military, marine, rail, oil and gas, mining and outdoor applications. 5, 7, 8 or 10 port Industrial DIN Rail Ethernet Switches. Fast Ethernet or Gigabit. Optional fiber ports with ST, SC or SFP connectors. PoE/PoE+ PSE capable models that are fully compliant to IEEE 802.3af/at.


Surge Protectors

Protect CAT5/6/7 data lines, PoE equipment and SHDSL telecommunication interface from lightning, RFI, ESD and transient surge. Largescale equipment failures and data loss are far more expensive than the cost of installing a Surge Protection Device (SPD).


Serial Extenders:

Serial to Fiber

PSI-MOS Serial to Fiber Converters transparently connect RS232, RS422 and RS485 devices to fiber optic cable. By transmitting data over optical fiber, these serial media converters provide an economical path to extend the reach of serial devices.

Serial to Copper:

The PSI-MODEM-SHDSL/SERIAL to Copper Extender transparently extends serial data transmission up to 20 km [12.4 mi] across single twisted pair ( CAT5/6/7 ), coax or any existing copper wiring previously used in alarm circuits, E1/T1 circuits, CCTV and CATV applications.

Serial Isolator

Interface converter for the electrical isolation of RS-232 interfaces

RS232 to RS485 Converter

The PSM-ME-RS232/RS485-P bi-directionally converts RS-232 interface signals to the RS-485 2/4-wire and RS-422 standard.

RS485 Repeater

Boost, or amplify, RS-485 signals to cover longer distances with the PSM-ME-RS485 Repeater.


PoE Injectors

The Perle PINJ30 is a single port, high power PoE+ mid-span injector.  It acts as an intermediary device between a non-PoE switch and a PoE device to inject fully compliant power over the Ethernet cable.


Ethernet I/O Device Servers

Perle’s Ethernet I/O technology (IOLAN DS I/O Device Servers) enables comprehensive access and control of remote digital I/O, analog I/O, pulse I/O, relays and temperature sensors as well as connections of remote serial equipment on any IP network. The IOLAN DS I/O has the ability to monitor environmental alarms, intrusion detection, relay contact closures and equipment failure. Through remote operator or application control, opening and closing of integrated relay contacts or activation of digital output signals can be incorporated into any response of a critical event.


Remote Power Switches 

Perle’s Remote Power Switches (RPS) enable you to remotely power on/off/cycle Data Center equipment to reduce downtime, service costs and resources. Operate as an integrated solution with Perle IOLAN Console Servers or as a standalone device over Ethernet.


Serial Cards

Perle's Serial Card lines enable you to easily add RS232, RS422, RS485 serial ports to your PC or server. Compatible with PCI, PCI-X or PCI Express bus slots, Perle serial cards are the only products that support all major operating systems including Windows, Vista, Linux, Solaris, SPARC as well as SCO.


Parallel Cards

Perle's Parallel PCI card family enables users to add parallel ports supporting the full IEEE 1284 parallel port standard to their PCs or servers. These universal PCI cards meet the PCI and PCI Express standards that have been adopted by PC server manufacturers and are available in standard and low profile form factors. Serial-parallel PCI combo cards are also available for those applications that require both serial RS232 and parallel ports on a single PCI or PCI Express card interface.
