EPSON PHOTO PC 500 DIGITAL CAMERA
Serial meaning 2.5mm stereo headphone looking jack to DB9 or "atari joystick" looking plug? I had one on my first Toshiba PDR-M1 camera but that was like 9 years ago. You can probably find the pinouts online for that cable, I believe it is a standardized cable.
The stereo plug is wired to the PC serial port as shown in the
tip ring sleeve +---------------------------------+
| RxD | Gnd | TxD | 2.5 mm Stero Plug |
DB9*: pin 2 pin 5 pin 3 +---------------------------------+
DB9*: Optionally short together pin 4 (DTR) to pin 6 (DSR) and
pin 7 (RTS) to pin 8 (CTS)
The following table also describes the camera cable's wiring:
Plug DB9* Signal Name Direction
---- ---- ----------- ---------
- 1 Carrier detect (CD) input to PC
tip 2 Receive data (RxD) input to PC
sleeve 3 Transmit data (TxD) output from PC
- 4 \ Data terminal ready (DTR) output from PC
ring 5 | Signal ground (Gnd) -
- 6 / Data set ready (DSR) input to PC
- 7 \ Request to send (RTS) output from PC
- 8 / Clear to send (CTS) input to PC
- 9 Ring indicator (RI) input to PC
* Note that the cable's D-subminature DB9 RS-232 serial port connector
is female. This connector also goes by the historically more correct
name of "DE-9J".
If you have installed optional expanded memory, you may notice a delay between the time you press the shutter button and when the camera beeps. You can reduce this delay by pressing the button down halfway, holding it as long as necessary, and then pressing it down the rest of the way when you are ready to take the picture. The reason for this two-step shutter is to save battery power. After a picture is taken, compressed, and written to memory, the Sparc CPU shuts down to save the battery's power. When the shutter button is pressed halfway, the Sparc wakes up and stays in the ready state until the user presses the shutter button the rest of the way. Besides the delay in waking the Sparc, there is a variable delay which occurs prior to the Sparc being in the ready state. This delay is dependent on the amount of free flash memory.
What are the minimum requirements for Macintosh?
Make sure your system is a Macintosh 68040 or higher or PowerPC processor, System Software version 7.5 or later, 8MB RAM (16MB recommended), at least 25MB free hard disk space, CD-ROM drive, VGA monitor with at least 256 colors, serial communications port, and a mouse or other pointing device.
What are high resolution and standard resolution?
All pictures have 24-bit pixel depth, or 16 million colors at 144 dots per inch. The high resolution setting produces a standard size photo, 4.44" x 3.33" at 640 x 480 pixels. A wallet size photo of 2.22" x 1.67" at 320 x 240 pixels is produced using the standard resolution setting. Example: A picture with dimensions of 4.44" x 3.33" at a pixel count of 640 x 480 will have the same dpi as the same picture at a 320 x 240 pixel count with dimensions of 2.22" x 1.67" (dpi=144 x 144 or 20736 pixels per square inch). The larger picture will have a much higher resolution due to the fact that four times the pixels will define the same section of the picture in the larger photograph.
Why does it take so long to process a picture ?
All digital cameras require a few seconds of processing time per picture. During the processing time, the camera is enhancing the image, compressing it as a JPEG image file, and then writing to the flash memory.
How can I store more pictures in the camera?
The standard 2MB internal flash memory stores either 60 standard resolution images or 30 high resolution images.
EPSON Accessories offers the PhotoSpan 2MB memory module (A882401) which increases picture storage to 65 high resolution or 130 standard resolution images.
The PhotoSpan 4MB memory module (A882411) makes it possible to take 100 high resolution or 200 standard resolution images.
How long does it take to download pictures to my PC?
At 9600 bps, which is the default setting on the PhotoPC, it takes 55 seconds to download each image. If you increase the baud rate to 57600 bps, it takes 18 seconds to download a high resolution image. If you are using Windows 95, Windows 98 or Windows NT, you can download the image faster at a maximum baud rate of 115.2 kbps.
Telephoto and wide angle lenses
Yes, you can use different lenses with the PhotoPC. To find out what lenses are compatible with the PhotoPC, contact TIFFEN.
CanI use a non-EPSON AC adapter?
EPSON only guarantees the EPSON AC adapter for the PhotoPC 500. Other non-EPSON AC adapters are not recommended for use because they may damage the camera and possibly void the warranty.
