SCSxx05/SCSxx20 User Guide 1: Introduction

1-6

All devices attached to both the device ports and the terminal port must support

the RS-232C (EIA-232) standard. Category 5 cabling with RJ45 connections is

used for the device port connections and for the terminal port.

Device ports (numbered from port 1 to port 48) support seven baud rate options:

2400, 4800, 9600, 19200, 38400, 57600, and 115200 baud.

Network

The SCS network interface is a 10Base-T/100Base-TX connector, for use with a

conventional TCP/IP network using standard RJ45-terminated Category 5

cables. The system administrator must configure the network parameters before

the SCS can be accessed over the network.

Modem (SCSxx20)

The optional modem module connects to a conventional telephone line using

standard RJ11 modular telephone cable. The analog modem on the card

connects at speeds up to 38,400 baud. Any PPP features require a modem.

With the modem installed, the SCSxx20 supports:

 Plain Text TTY

 PPP connection, with PAP or CHAP authentication

 Callback connection

Note: Both the SCSxx05 and the SCSxx20 can work with an external

modem.

Power Manager

The SCSxx20 has an extra power manager port for connection to the Lantronix

Power Control Unit (PCU8). However, any available device port may be used as

the power manager port on the SCSxx05 and SCSxx20.

Access Control

The system administrator controls access to attached servers or devices by

assigning access rights to up to 128 user profiles. Each user has an assigned ID,

password, and access rights. Other access options may include externally

configured authentication methods such as NIS and LDAP.
