The MicronEye's transmission speed (baud rate) is normally set at the factory to 153,000 baud for the IBM, Apple and Commodore 64 computers. A baud rate of 76,800 is used for the TRS-80 Color Computer. The RS-232 version is factory set to 9,600 baud. If you wish to change the baud rate, proceed according to the following paragraph.
Modifying the baud rate of the MicronEye requires some soldering so caution is advised. The baud rate on the MicronEye is set by soldering two wire jumpers as specified below. An end of one wire has been soldered to pad 9 (located beside IC D1) and one end of the other wire has been soldered to pad 10 (located between IC D5 and IC E5). These two connections are never changed so they do not have to be removed. However, the other end of both of the wires should be unsoldered and resoldered according to the desired baud rate.
Beside IC B5 are 8 pads. Pads 1, 4, and 8 are labeled on the board. To select one of the five standard baud rates, use the table below to rejumper for the desired baud rate.

Other baud rates are obtainable by soldering the wires to certain pins on IC B5. However, this practice does not make a reliable connection and is not recommended. If one of the baud rates listed below is required, use the following table to make the proper connections:
