Page 5: Introduction
Introduction The R-31JP is designed for easy assembly by the hobbyist or prototyping engineer. The components are assembled on the top side as marked, i.e., the side with the silk screen overlay of component outlines and designations. All of the integrated circuits are inserted into sockets. -
Page 6: Soldering
Soldering Use a low power (about 30 Watts) soldering iron. Heat the component lead and the pad with the iron, and then apply solder to the lead and pad. Solder should be shiny in appearance. Be careful not to deposit too much solder on the joints. The most common problem with board assembly is shorted pins or tracks due to excessive solder. -
Page 7: Assembly Steps
Assembly Steps Familiarize yourself with the board, the components, and the layout. Also refer to the bill of materials at the end of this assembly manual. DB9 connector slide switch disc capacitors notch Board layout Discrete components (resistors and diodes) 3.1.1 Resistors These resistors have no polarity. -
Page 8: Diode D3
When the notch is to the left, and viewed from the top, the lower leftmost pin is pin 1. On the R-31JP board, the pads of pin 1 of the Integrated Circuits (ICs) are square. All other IC pads are circular. The orientation of the sockets is critical. -
Page 9: Resistor Network R1
R1 is a resistor network which contains 9 resistors with a common terminal. The common terminal is marked on the resistor networks with a line or a dot. The R-31JP board is also marked by a line where the common terminal is to be inserted. In addition, the pad for the common terminal is square. -
Page 10: Discrete Components (Capacitors And Crystal)
Light Emitting Diodes (LEDs) D1 and D2 Either D1 or D2 is lit when the R-31JP is powered, depending on the position of the slide switch. It is recommended that a red LED is used for D1 (MON) and a green LED for D2 (RUN). -
Page 11: Visual Inspection
Visual Inspection Most of the problems in assembling the R-31JP are due to faulty solder joints. Inspect each solder joint. Look for missing solder, too much solder, shorts between pins or tracks due to excessive solder. Remove excessive solder with solder wick. Care taken for a thorough visual inspection often saves time in the long run. -

Communicating with the PC Host Connect the R-31JP to either the COM1 or the COM2 port of the host PC. Run READS. Once in Reads select the demo program Deom00.ASM. Once in the editor, press F10 for the menu. - Page 13 Next, assemble the various demonstration programs given on the distribution disk. Download the object codes and run on the R-31JP. Refer to the R-31JP/READS User’s Guide and the program listings for specific information on the demonstration programs. - 9 -...
