Using the Modem feature

Background

The modem feature allows the SVxx41HDIE to act as an Internet connection server for increased security and flexibility in connecting with the host computer. Unlike the TCP/IP connection used with the standard Web configuration and VNC clients, the modem creates a one-to-one connection between the SVxx41HDIE and the computer you are using to manage the host computer that is essentially private, as it bypasses the public Internet completely. Note: this feature requires both an external modem (most standard connection protocols are supported) and a dedicated phone line that can be connected to the modem for external access. While it is possible to use the modem feature through some PBX systems, this increases the complexity and reduces the performance of the connection. For clarity, the instructions presented here assume that the modem is connected to a typical POTS (plain old telephone system) line that is not routed through a phone management system or shared with other devices. If you wish to use this feature through a PBX system, it may require some experimentation and additional support from your telecom services provider, and is not supported by StarTech.com.

Connecting a Modem

Modem Connection

The SVxx41HDIE will work with virtually any Hayes-compatible modem that recognizes the standard AT command set. Some modem manufacturers offer “enterprise” grade modem products (at a premium price) that include technology to improve the stability of connections; whether this type of product would be beneficial to your application depends on whether you consider the modem connection to be mission-critical, the quality of your telecom infrastructure, and your budget for implementing this solution. The model of modem attached is essentially transparent to the SVxx41HDIE.

It is important to note that modems that offer “56K” (or 56,000 bps) connections often achieve connection speeds that are far lower than their maximum capabilities. Given the limitations of telecom infrastructure (many locations have yet to implement fully digital switching technology, and still rely on older analog technology for some segments), the maximum “upstream” transfer rate is limited to a maximum of 33,600 bps between two modems; the “downstream” rate is often within a similar range for a typical connection. Therefore, speeds below 56,000 bps do not indicate a problem with the modem or the SVxx41HDIE, but simply reflect the line conditions at the time the connection is made.

The Serial port can be used for serial port configuration when the modem is connected. It requires the use of a null modem serial cable.

Place the modem near the SVxx41HDIE and an available telephone jack. Connect the modem to the telephone jack, data cable, and power source according to the instructions
