2 - Installation 9 Chapter 2 - Installation Introduction This chapter will provide you with the basic steps necessary to install and configure your MultiModemZDX. Before attempting any procedure, be sure to read the safety warnings in the following section.
MT3334ZDX/V Owner's Manual 10 To install your MultiModemZDX: 1. Attach the MultiModemZDX to dial-up phone lines using the RJ11 telephone cord. This is accomplished by plugging one end of the cable provided with the MultiModemZDX into the telephone jack in your home or office; and plugging the other end into the LINE jack on the MultiModemZDX.
2 - Installation 11 ✳ # Figure 2-2. MultiModemZDX Connections.
MT3334ZDX/V Owner's Manual 12 LED Indicators The MultiModemZDX has ten LED indicators (Figure 2-3) to report status (such as verifying proper installation) and line activity (such as monitoring the status of a connection). Figure 2-3. Front Panel TD Transmit Data.
2 - Installation 13 CD Carrier Detect. This LED lights when a valid carrier signal from another modem is detected. 33 V.34. This LED is lit when the modem is connected in V.34 mode at 33,600 bps. 14 V.32 bis . This LED is lit when the modem is connected in V.
MT3334ZDX/V Owner's Manual 14 TR Terminal Ready. When TR is lit, the MultiModemZDX can answer an incoming call. This signal (TR or DTR) provides a means for the terminal or computer to control the MultiModemZDX's connection to the communications channel.
2 - Installation 15 Operating Your MultiModemZDX You control your MultiModemZDX by issuing AT commands and setting S-Registers. Right now your MultiModemZDX is set up for the most typical user applica.
MT3334ZDX/V Owner's Manual 16 Remote Configuration The Remote Configuration feature is a network management tool that allows you to configure modems remotely. This means you could configure modems anywhere in your network from one location without having to visit the sites or rely on remote users to follow your instructions.
2 - Installation 17 Software Configuration Communications software must be configured to work with the MultiModemZDX, your computer, and the remote system it is calling.
MT3334ZDX/V Owner's Manual 18 Hardware/Software Confirmation To confirm that your modem (hardware) and communications package (software) is working properly: 1.
2 - Installation 19 Troubleshooting Your MultiModemZDX was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection or if you experience data loss or garbled characters during your connection, it is possible that the modem is defective.
MT3334ZDX/V Owner's Manual 20 The Modem Does Not Respond to Commands • Make sure the modem is plugged in and turned on. (See “None of the LEDs Light When the Modem Is On.
2 - Installation 21 • Peripheral expansion cards, such as bus mouse and sound cards, may include a serial port preconfigured as COM1 or COM2. The extra serial port, or the card itself, may use the same COM port, memory address, or interrupt request (IRQ) as your communications port.
MT3334ZDX/V Owner's Manual 22 The Modem Dials But Cannot Make Connection There can be several reasons the MultiModemZDX fails to make a connection. Possibilities include • lack of a physical connection to the telephone line. • a wrong dial tone.
