1.8Controls on PC Board

The MultiModem is designed on a single printed circuit (PC) board. This board contains one 16- position DIP-Switch (numbered 1-16). The DIP-Switches are accessible through a cut-out on the side of the modem. There is also a knob which is used to adjust the speaker volume. This knob is accessible through the modem's rear panel. The sixteen DIP-Switches control various modem options or set default values for Command Mode operation. There is a difference in how several of the switches operate depending on whether you are in synchronous or asynchronous mode. Refer to the switch label on the bottom of the modem for an exact list of the switch functions in asynchronous and synchronous operation.
