Figure 16: Keypad Interface Connector 3 Troubleshooting 3.1 The display does not turn on when power is applied. • First, you will want to make sure that you are using the correct power connector. Standard floppy drive power cables from your PC power supply may fit on the Power/Data Connector however they do not have the correct pin out as can be seen in figure 6 on page 6. Matrix Orbital supplies power cable adapters for connecting to a PC, which can be found in the Accessories Section on page 2.
NOTE I2 C communication will always require pull up resistors. • Finally, you may reset the display to it’s default settings using the Manual Override Jumper, see Section 2.6 on page 11. 3.3 The display module is communicating, however text cannot be displayed. • A common cause may be that the contrast settings have been set to low. The solution to this problem is to adjust the contrast settings. The default setting that will work in most environments is 128.
4.1.2 Serial Communication In addition to being able to communicate via I2 C the PK162-12 communicates natively through the RS232 protocol at a default baud rate of 19,200 bps and is capable of standard baud rates from 1200 to 57600 bps. Furthmore the PK162-12 is also capable of reproducing any non-standard baud rate in between using values entered into our baud rate generation algorithm and set through command 164 (0xA4).
Parameters Description Parameter speed Length 1 Description Hex value corrisponding to a baud rate. This command sets the RS-232 port to the specified [speed]. The change takes place immediately. [speed] is a single byte specifying the desired port speed. Valid speeds are shown in the table below. The display module can be manually reset to 19,200 baud in the event of an error during transmission, including transmitting a value not listed below, by setting the manual override jumper during power up.
Description This command sets the RS-232 port to a non-standard baud rate. The command accepts a two byte parameter that goes directly into the modCrystalSpeed − 1 to calules baud generator. Use the formula, speed = 8×DesiredBaud culate the [speed] for any baud rate setting. The speed can be anywhere from 12 to 2047 which corresponds to a baud range of 977 to 153,800 baud.
