1.3 Connecting to a PC The PK202-25 connects seamlessly to a PC and it is an excellent means of testing the functionality. To connect your display to a PC, you will require a standard RS-232 9-pin serial cable such as the one pictured , as well as a modified 5V power adapter such as the one pictured in...
1.4 Installing the Software 1.4.1 uProject uProject was designed by Matrix Orbital to provide a simple and easy to use interface that will allow you to test all of the features of our alpha numeric displays. To install uProject from the Matrix Orbital CD, follow the following steps: Insert the Matrix Orbital CD-ROM into the CD drive Locate the file, uProject.exe, which should be in the “CD-drive:\Download”...
Manual Override Figure 12: PK202-25 2.1 DB-9 Connector The PK202-25 provides a DB-9 Connector to readily interface with serial devices which use the EIA232 standard signal levels of 12V to 12V. It is also possible to communicate at TTL levels of 0 to +5V by setting the Protocol Select Jumpers to TTL.
In order to provide power through pin 9 of the DB-9 Connector you must place a solder jumper on the Power through DB-9 Jumper pictured in below. The PK202-25 allows all voltage models to use the figure 14 power through DB-9 option, see table 1 on the following page for display module voltage requirements.
2.4 General Purpose Outputs A unique feature of the PK202-25 is the ability to control relays and other external devices using a General Purpose Output, which can provide up to 20 mA of current and +5Vdc from the positive side of...
2.5 Dallas 1-Wire Bridge In addition to the six general purpose outputs the PK202-25 offers a Dallas 1-wire bridge, to allow for an additional thirty two 1-wire devices to be connected to the display. See Section 8.1 on page 33.
2.6 Manual Override The Manual Override is provided to allow the PK202-25 to be reset to factory defaults. This can be particularly helpful if the display module has been set to an unknown baud rate or I C Slave Address and you are no longer able to communicate with it.
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 10 on page 7. Matrix Orbital supplies power cable adapters for connecting to a PC, which can be found in the Accessories Section on page 1.
The last step will be to check the Power / Data Connector on the PK202-25. If the Power / Data Connector has become loose, or you are unable to resolve the issue, please contact Matrix Orbital, see 14.5 on page 56 for contact information.
