PC Board Controls

The MT5600BR-V92 is designed on a single printed circuit board. This board contains sixteen DIP-
Switches. There is a two-position "Out of Service" (OOS) toggle switch that extends from the front of the
modem circuit card. There is also a two-position TEST/OOS berg jumper located towards the back and
center of the card.
The sixteen DIP-Switches and berg jumper control various modem options or set default values for the
MT5600BR-V92 Command mode. There is a difference in how several of the switches operate depending
on whether you are in synchronous or asynchronous mode (DIP-Switch #12).
Most communications software packages have installation procedures of their own, which call for certain
modem DIP-Switch settings. If you are using such a package, follow the software's instructions.

DIP-Switch Settings

The vast majority of installations are similar, with the MT5600BR-V92 being used to dial up a remote
installation where the call is automatically answered. The factory default DIP-Switch settings are based
on this assumption. The following is a brief description and summary of the MT5600BR-V92's DIP-Switch
