SCS1600/3200 User Guide 1: Introduction to the SCS Family

Protocol Support

The SCS supports the TCP/IP network protocol as well as:

 SSH, Telnet, and Rlogin for connections in and out of the SCS

 DNS and WINS for text-to-IP address name resolution

 SNMP for remote monitoring and management

 FTP for file transfers and firmware upgrades

 TFTP for firmware upgrades

 BOOTP, RARP, and DHCP for IP address assignment

 HTTP for easy browser-based configuration

 NTP for time synchronization and authentication

 NAT for enabling private networks to share a connection to the Internet.

SSH (Secure Shell): A secure transport protocol based on public-key cryptography.

Telnet: This terminal protocol provides an easy-to-use method of creating terminal

connections to any network host supporting Telnet.

Rlogin: Allows you to initiate a TCP/IP login session.

DNS (Domain Name Servers): Lets a network nameserver translate text node names

into numeric IP addresses.

SNMP (Simple Network Management Protocol):Commands that allow system

administrators to monitor and manage nodes on a LAN (Local Area Network) and

respond to queries from other network hosts. One community name can be configured

with read/write access. Refer to the SCS Reference Manual for SNMP configuration

instructions.

BOOTP, RARP, and DHCP: Methods for automatically assigning an IP address and

network settings.

NTP (Network Time Protocol):Used to synchronize time on networked computers and

equipment.

NAT (Network Address Translation): Allows private networks to share a single

connection to the Internet. With Port Mapping, specific IP Ports can be mapped from the

Internet to a private IP address and port.

This chapter provides a physical description of the unit and requirements for installing

and connecting it. The topics include:

 Connections

 Pinouts

 Cables and Adapters

 Specifications

Connections

The SCS1600 and SCS3200 are distinguished by the number of asynchronous RJ45

serial ports they are equipped with. The SCS1600 has 16 ports, while the SCS3200 has

32 ports. Both units include an AUI connector and a UTP port (10/100BASE-T) for

Ethernet connections. They both support baud rates between 300 and 230,400 bits per

second.

Note: The Reset button returns the SCS to its factory default configuration when

you press and hold it during the power-up and boot process. Resetting to factory

default will enable DHCP.

Pinouts

The SCS3200 has 32 asynchronous RJ45 serial ports. The SCS1600 has 16

asynchronous RJ45 serial ports. Pinout information for these ports is discussed in the

following sections.

RJ45 Serial Connectors

Lantronix servers are RS-423 compliant and are thus limited by the equipment at the

remote end of the serial line. If the SCS is connected to an RS-232 device, it is subject to

the RS-232 limits shown below. If connected to an RS-423 device, it is subject to the RS-

423 limitations.

RS-232 lines are limited to 15m (50 ft) in length at 9600 baud, and 2 m (6 ft) at 115.2K

baud. RS-423 lines are limited to 300m (1000 ft) at 9600 baud, 85m (260 ft) at 115.2K

baud, and 40m (120 ft) at 230.4K baud. They will generally work at longer lengths.

The pinout of the serial ports is displayed below.

SCS1600/3200 User Guide 2: Connections and Physical Requirements

RJ45 Serial Connector

RJ45 to DB25

If you are connecting an RJ45 port to a DTE device (such as a terminal) that has a DB25

connector, you will need to use an RJ45-DTE DB25 adapter. To connect an RJ45 port to

a DB25 connector on a DCE device, you will need an RJ45-DCE DB25 adapter. The

pinout information for both connections is shown below.
