Secure Ethernet I/O
Perle’s Ethernet I/O technology (IOLAN
SDS I/O Device Server) enables secure access
and control of remote digital I/O, analog I/O, pulse I/O,
relays and temperature sensors as well as secure connections
of remote serial equipment on any IP network. The IOLAN SDS
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.
Management, Monitoring and Control of High-Value
Distributed I/O Assets
The monitoring and protection of high-value distributed
I/O assets involves more than simple secure access to its
data, it also involves the protection and control of its
physical environment along with the ability to take corrective
action when necessary. Digital and analog sensors, proximity
and mechanical switches, relays, pushbuttons, temperature
and humidity sensors can assist in determining the integrity
and security of the asset’s local environment. Information
from these sent back to a central support location over a
network can help an enterprise react more quickly to an important
event or failure. IOLAN SDS I/O Device Servers are ideal
for these applications.

Secure Ethernet I/O Connectivity
IOLAN
SDS I/O Device Servers enable administrators to securely
acquire information from remote I/O (digital and analog based)
devices across an IP network. Sensitive server data gathering
and control information between SCADA server and remote
I/O is protected through powerful encryption ciphers such
as AES, 3DES, RC4, RC2 and CAST128. Authorized administrative
access to an IOLAN SDS is assured via standard authentication
schemes such as RADIUS, TACACS+, LDAP, Kerberos, NIS and
RSA Security’s SecurID tokens.
Recognized as the most secure method for communicating to
remote private networks over the Internet, the IPSec standard
provides robust authentication and encryption of IP packets
at the network layer of the OSI model. As a standard it is
ideal for multi-vendor interoperation within a network, providing
flexibility and the ability to match the right solution for
a particular application.
With the IOLAN VPN Gateway feature, IOLANs can participate
within an IPSec VPN infrastructure simplifying deployments
connecting to critical I/O assets that use serial communications.
Extended Temperature Support
The IOLAN SDS I/O Device Server addresses the need for
connecting remote I/O and serial devices that operate in extreme
temperatures –40C to +74C (-40F to +165F) to an enterprise’s
IP network.
Access I/O Devices over Ethernet using Popular
Central Applications
An IOLAN I/O Device Server is ideal for remote
I/O management
using common SCADA or OPC Servers using MODbus/TCP protocol
as well as Network Management Systems ( NMS) utilizing SNMP.
Flexible and Reliable COM/TTY Access to Ethernet
I/O
An IOLAN I/O Device Server is ideal for connecting COM/TTY
based applications such as MODbus ASCII/RTU to remote
I/O devices. Perle’s TruePort
re-director provides
COM port or fixed TTY connections across an IP
network.
An Application Program Interface ( API ) is also available
so that custom applications can be developed to access distributed
I/O channels attached to remote IOLAN I/O Device
Servers. Common serial applications such as Visual Basic
can be used to send IOLAN API commands to remote IOLAN I/O
Device Servers across an IP network. This API is available
for the most popular operating systems today.
Universal I/O
The IOLAN SDS I/O Device Server connects to a wide variety
of distributed I/O devices.

Universal I/O on IOLAN I/O Device Servers provides
flexibility when used across a wide array of environments.
Individual digital channels can be configured as either inputs
or outputs. Analog Inputs can support a broad range of voltage
or current type devices including industrial grade temperature
sensors such as thermocouples and RTDs.
Models with integated solid state relays can be used to control
remote contact closures.
Automated response to alarm conditions
IOLAN SDS I/O Device Servers have the capability
of measuring input conditions and intelligently alerting
enterprise resources such as central TCP/IP based applications,
Syslog, SNMP or individuals via email. By instantly generating
alerts when pre-defined threshold levels have been exceeded,
alarm notifications can be passed along when needed. This
eliminates the packet based overheads associated with polled
environments.
Rugged Industrial-Grade Design
Compact and protective metal enclosure for wall mount or
DIN rail mounting environments. Industrial grade unit protection
is provided though optical isolation of I/O channels of
2000 Vrms, Ethernet isolation of 1500 Vrms, open/short
detection logic on RTD/Thermocouple inputs and 15,000 volts
electrostatic discharge protection across all serial pins.
Advanced IP Technology
With support for Next Generation IP (IPv6) the IOLAN range
provides organizations with investment protection to meet
this rapidly growing standard. 
Demand for IPv6, which is
compatible with IPv4 addressing schemes, is driven by the
need for more IP address. With the implementation and rollout
of 3G cellular networks, a robust method is needed to handle
the huge influx of new IP addressable devices on the Internet.
In fact, the US Department of Defense has mandated that
all equipment purchased from 2005 be IPv6 compatible with
full implementation by 2008. In addition, all major Operating
Systems such as Windows, Linux, Unix and Solaris, as well
as routers, have built-in support for IPv6.
It is therefore important for end users and integrators
to select networking equipment that incorporates the IPv6
standard. The IOLAN line with support for IPv6 already built
in, is the best choice in serial to Ethernet technology.
Lifetime Warranty
The Perle IOLAN SDS is backed by the best service and support
in the industry including Perle’s unique lifetime warranty.
Since 1976 Perle has been providing its customers with networking
products that have the highest levels of performance, flexibility
and quality.
