Installation AT-TS90TR Series Switches use the TCP/IP-family Trivial File Transfer Protocol (TFTP) to download other units internally, whether or not your network is configured with IP parameters. In a non-TCP/IP installation, the TFTP protocol will be transparent to the other (non-IP) devices on the network. - Page 15 AT-S6 Firmware Module for AT-TS90TR Switch Table 1: RS232 Cable AT-TS90TR DB9 Signal Name Terminal DTE DB25 Modem DCE DB25 — — — — AT-TS90TR Switches support various commonly used data rates (baud rates), from 75 bps to 19.2 kbps, as well as an automatic baud rate detection mode.

Page 17: Setting Up Management Software
Chapter 3 Setting up Management Software Your AT-TS90TR has pre-installed the Omega Console software which gives access to the AT-TS90TR internal Management Software and network management agents. The Omega Console software is accessible either through the RS232 serial port or remotely from a management station by means of a Telnet session, if the IP address is already configured. -
Page 18: Getting Started - Ethernet
Setting up Management Software If you are running Windows on your PC to access Omega, you can use the ® ® Note Microsoft Windows terminal icon. Simply connect your PC to the RS232 management port on the hub, select the Windows terminal icon and press twice to initiate a session. -

Page 29: Ethernet Parameters
AT-S6 Firmware Module for AT-TS90TR Switch Ethernet The AT-3690TR offers the choice of store-and-forward (the default) or cut- through switching strategies. In both store-and-forward and cut-through Parameters switching modes, the AT-3690TR buffers data traffic when there is competition for network resources. This technique, with minimal delay, tends to isolate rather than propagate error conditions. - Page 30 System Administration Figure 18: Terminal Configura- tion Submenu There are several options available which affect the characteristics of your terminal and the serial interface. Presently configured (or default) options are highlighted with an arrow (“>”). Changes to the configured terminal characteristics (terminal type and half/full duplex) take effect immediately.
