IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.5 27

About the IOLAN

The IOLAN is an Ethernet communications/terminal server that allows serial devices to be connected

directly to LANs. The IOLAN can connect to a wide range of devices including:

z Terminals for multi-user UNIX systems

z Data acquisition equipment (manufacturing, laboratory, scanners, etc.)

z Retail point-of-sale equipment (bar coding, registers, etc.)

z PCs using terminal emulation or SLIP/PPP

z Modems for remote access and Internet access

z ISDN adapters for branch remote access and Internet access

z All types of serial printers

The performance and flexibility of the IOLAN allows you to use a wide range of high speed devices

in complex application environments. The IOLAN products will work in any server environment

running TCP/UDP/IP.

IOLAN Family Models

The IOLAN comes in several different models to meet your network needs:

z DS—Offered as a 1-port unit (DB25M, DB25F, RJ45, and DB9M interfaces available), this

model provides general IOLAN functionality and supports software configurable serial interface

protocols EIA-232/422/485.

z TS—This model is available with two serial ports (RJ45 only) and supports EIA-232 only. The

TS model is similar to the DS model supporting only general IOLAN functionality.

z SDS—This model is available in both desktop and rack mount configurations. Both models

support software configurable serial interface protocols EIA-232/422/485. The SDS model has

the advanced secure IOLAN feature set in addition to the general IOLAN functionality.The SDS

models also include the “Electric Utility” variants which include both HV (High Voltage AC and

DC) and LDC (Low Voltage DC) models as well as the TELCO-NEBS LDC model. The Iolan

SDS M model supports 1 or 3 serial ports with an intergrated V.92 modem .The SDS P is

802.3af Power over Ethernet complaint. Ethernet interface speeds of 10/100 Mbps.

z STS—This model comes in two desktop models and several rack mount configurations. All

models support EIA-232 only except for the STS P which utilizes Power over Ethernet

technology. The STS model has the advanced secure IOLAN feature set in addition to the

general IOLAN functionality.

z SCS—This model comes in several rack mount configurations. All models support EIA-232

only and have an internal PCI card interface. The internal PCI card interface can be used either

for installation of a V.92 modem card or optionally a wireless fiber card. The SCS model has the

advanced secure IOLAN feature set in addition to the general IOLAN functionality. MDC—

Offered as a 4-port and 8-port unit (RJ45 only), this model is a medical unit compliant with IEC
