R4i SDHC Card Problems and Solutions

I recently started having problems with my R4i SDHC cartridge, after changing the MicroSD card. The problems started when I swapped my old 2GB card to a SDHC one.

It would act slowly, corrupt save games and display "Savfile not founded! [sic]" message when some games are loaded.

To solve it, I did the following:
  1. Copy all ROMs to the desktop.
  2. Reformat the card using the Panasonic SD Formatter (http://panasonic.jp/support/global/cs/sd/download/index.html). I used version 2.0, with the default settings.
  3. Replaced the spaces of the ROMs and .sav files with underscores ('_').
  4. Copied everything back to the newly formatted card.
  5. Updated the R4i's kernel (check their website). 
A couple of ROMs still failed to load (complaining about the Savfile), but once I moved to the root of the card, they were fine.


For the record, I use the R4i to mostly to write homebrew apps, and I do own the original cartridges of any ROMs I have loaded on it.

Setting up an AXIS 241QA Video Server to Control an Everfocus PTZ Camera

Camera Setup
1. Set the protocol on the camera to Pelco-D.
2. Set the baud rate to 9600bps.
3. Give a unique address to the camera.

For the Everfocus EPTZ500 cameras, the setup DIP switches will look like: 10 00 00 00

AXIS Server Setup

1. Set the RS485 mode to “Pan Tilt Use”.
2. Load the Pelco driver. It can be found at the Axis website (there is a link in the server’s web UI).
3. Check the “Force Install” checkbox before hitting ok.
4. Set the device type to “Generic”.
5. Set the Address to be the same as the camera’s address.
6. Set the RS485 port settings as follows (they are at the bottom of the page):
Baud Rate: 9600
Data Bits: 8
Stop Bits: 1
Parity: None

Cable Connection
1. The Yellow (+) cable on the Camera goes to the RS-485-A pin on the Axis (Pin 11 for the 241QA).
2. The Orange (-) cable on the Camera goes to the RS-485-B pin on the Axis (Pin 12 for the 241QA).

Troubleshooting
1. If something doesn’t work, make sure that Camera’s address is reflected correctly in the server’s port/video settings.

AMX and Procon Equipment

At work we are using a number of AMX Novara panels to automate the teaching lecterns/cabinets.

As Novara panels and the Solecis integrators used to be produced by Procon, there can be a bit of confusion regarding the model numbers.

Here is a small table with what is what (at least the things we use :)):

AMX NameProcon NameDescription

On a similar note, most of the Novaras don't have the pin-out of the programming port printed on their back, so here it is:
