7.1Introduction

There are several DIP-Switch options on the modem’s printed circuit (PC) board. The DIP-Switches are accessible through a cut-out on the side of the modem. This chapter explains the modem’s printed-circuit board options. Sixteen DIP-Switch settings and the modem's speaker volume control are explained in detail, including all default settings.

Switch #1

Forced DTR -- "DTR"

(Asynchronous/Synchronous Mode/Leased Line/Dial-Up)

The modem must have a high DTR signal in order to operate. DTR is provided to the modem by the terminal or computer to which it is attached, through pin 20 of the RS-232C/V.24 interface. If your terminal or computer is not providing DTR to the modem, you can force the DTR signal high with DIP- Switch #1.

DTR function normally DTR forced On Factory Default Setting

=Switch #1 DOWN

Switch #2

Flow Control - &E4/&E5

(Asynchronous Mode/Leased Line/Dial-Up)

With Hardware Flow Control, the modem uses its RS-232C/V.24 interface to control the flow of data from the computer or terminal to which it is attached. The CTS signal on Pin 5 of the RS-232C/V.24 is brought low to stop the flow of data, and is brought high to restart it. Place DIP-Switch #2 in the UP position to enable Hardware Flow Control (&E4). Xon/Xoff Flow Control (&E5) is another flow control method. Xon/Xoff characters in the data dictate the start and stop of data flow from the computer or terminal. Place DIP-Switch #2 in the DOWN position to select Xon/Xoff Flow Control.
