Host Problems

Host Problems

Cannot access a host on a local network, verify:

zThe network address is correct.

zThe subnet mask is set correctly and reflects the network configuration.

zThe broadcast address is set correctly and reflects the network configuration.

Cannot access a host on a remote network:

zUse the show route command to verify that there is a route to the remote host. If no gateway is specified, verify that a default gateway is specified. Ping the default gateway to check if it is working.

zConsider the situation beyond the gateway; for example, are intermediate gateways and the remote host available? Also, check the messages returned by the ping command; for example, that a particular host or gateway is unreachable.

Gateways added into the gateway table are ignored by the Device Server:

zHave you used BOOTP and entered a single static gateway in the bootptab file entry? If yes, the other gateways will be ignored.

Access to host lost after a few minutes.

zIf the route to this host goes through routers, make sure those routers are all sending RIP packets across the networks.

Login Problems

You have lost or don't know your password (as Admin user).

zYou must reset the Device Server to its factory default settings using the Reset switch on the rear panel. There is no procedure to access the Device Server without a password.

Problems with Terminals

The following section concerns problems with the appearance of data on your terminal screen.

The Device Server logs me out after a few minutes:

zCheck the Idle Timer value set for the user. The default setting for the Idle Timer for all users is 0 seconds (does not timeout).

Corrupt data.

zCheck your line settings (baud rate, stop bits, etc.)

Missing data.

zVerify that the same type of flow control is set in both your terminal and on the Device Server’s port.

Error message not permitted on a dumb terminal after typing the CLI command

screen.

zSet your Line to Termtype VT100, ANSI or WYSE60 (or other form of terminal emulation, if you have downloaded one). The default line type in the Device Server is Dumb, which does not support the graphics characters necessary to view the text-based menus.

Screen corruption when using the text-based menu system.

zVerify that the terminal setup in the Device Server matches your terminal.

zVerify that entries in the term file match your terminal setup.

zIf using a PC/computer, verify that the type of terminal emulation selected in your application matches those supported by the Device Server.

The TS2 model is particularly noted for its dual serial ports, enabling simultaneous communication with multiple devices. This capability is invaluable for applications requiring real-time data transmission, such as remote monitoring and automated control systems. The DS1 model, on the other hand, is designed for single-port use, making it an ideal solution for smaller-scale operations or specific single-device connections.

Both the TS2 and DS1 incorporate advanced features such as configuration through a web interface, which simplifies setup and management. Users can easily access device settings and monitor performance metrics remotely, enhancing operational efficiency. These devices also support various network protocols such as TCP/IP, UDP, and ICMP, ensuring compatibility with a wide range of network architectures.

In terms of security, Perle Systems prioritize user data protection. The TS2 and DS1 offer features including SSL encryption and SSH protection, providing an added layer of security for sensitive information transmitted over the network. This is particularly important for industries where data integrity and security are paramount, such as healthcare and finance.

Additionally, the rugged design of both devices ensures reliable performance even in harsh environments. With extended temperature ratings and robust housing, the TS2 and DS1 can operate in diverse conditions without compromising functionality.

To summarize, the Perle Systems TS2 and DS1 provide a reliable and flexible solution for connecting legacy serial devices to modern networks. With their support for multiple serial protocols, web-based management, robust security features, and rugged design, these devices cater to a variety of industries looking to modernize their communication infrastructure while maintaining existing equipment. Whether for large-scale operations or smaller implementations, the TS2 and DS1 equip businesses with the tools needed for effective serial communication in an IP-driven world.
