Q2172565
For each analog signal you wish to read that is a 4-20mA current loop you will need to install a shunt at
this time. The shunt locations correspond to the analog channels they are adjacent to. Figure 4 shows
the locations of the shunts relative to the MAX1270 A/D converter IC. It also shows the shunt for analog
input channel 1 installed properly.
Programming Port Connection
Connections Sout, Sin, ATN, and GND are for the serial port. This diagram depicts exactly how to wire
these connections to a standard DB9 PC serial port. Please note the jumper wire connecting pin-6 to pin-
7 on the DB9 is not necessary providing that you use BASIC Stamp Editor software version 1.2 (or later).
