3. Connect the RM-4 to the LAN and verify that it can be pinged.
4. Access the RM-4 using the RM-4 User Interface and log on.
5. Click the “System Files” tab and click the “Request” button to obtain the directory
information of the RM-4.
6. Select either “Program A” or “Program B”, whichever is not in use.
7. Click the “Load file” button, to load the file to be sent to the appropriate partition.
8. Click the “Send file” button, confirm the correct file partition, and wait for the new
code to be uploaded and saved to the RM-4. This should take from 30 to 60 seconds.
9. The RM-4 User Interface should indicate whether the upload was successful.
10. Click the “Test code” button to test the new code.
11. When satisfied with the new code, press the “Set default” button.
NEVER power down the RM-4 while it is doing a upload. This could have catastrophic results.
Internal Configuration Options
Power Supply
The as-shipped sheet supplied with the RM-4 should indicate whether it is standard configuration
(5V) power, or whether it is configured for 12V operation.
Note that in either case, 12V power
should never be applied to the 5V input pin. Please refer to the connector pinout in the appendices.
If you are still unsure which power supply to use, use the following procedure to identify the
internal configuration.
This procedure should only be done in an anti-static environment. Ensure
that you and the board are electrically grounded, and then remove the screws from the rear panel of
the RM-4. Take off the rear panel, and slide the PCB out of the bottom tray of the enclosure. Check
for the installation of the following components. If F2 and U16 are installed, and the jumper J4 is
cut, then the unit is configured for 10-16V operation. If only F1 is installed, then the unit should
only be operated from 5V input.
Assembling the RM-4 is the reverse of taking it apart. When sliding the PCB into its tray, ensure
that the LED light pipe “H3” fits right into the cutout in the front panel.
Factory Test Port
The factory test port is an RJ-45 connector using RS-232 levels port used for factory testing and
firmware downloading. Its pinout is given in Appendix B.
