D30/31 Mode Translating Parameters Zoom speed Cameras EVI-D30/D31 EVI-D70/P Parameters 02h (Min. speed) to 07h (Max. speed) 00h (Min. speed) to 07h (Max. speed) Translation of commands Accepted parameters Translation 00h, 01h Translates to 02h Values greater than 02h Accepts as is Translation when answering inquiry commands Parameters Translation 0000h to 4000h Translates within a rage of 0000h to 03FFh The D70/P's parameters are translated to those of the D30/D31. However, even if the zoom position value is less than 08D0h (closer to the wide side), the camera sends back 0000h to the controller. On the other hand, even if that value is greater than 3B4Bh (closer to the telephoto side), the camera sends back 03FFh. Focus position Zoom position Cameras EVI-D30/D31 EVI-D70/P Parameters 0000h (WIDE) to 03FFh (TELE) 0000h (WIDE) to 7AC0h (TELE, digital 12×) Translation of commands Accepted parameters Translation 0000h to 03FFh Translates within a rage of 08D0h to 5700h The EVI-D70/P translates the parameters to let the camera obtain the same zoom position that is defined by the D30/D31's parameter. (The values given below are calculated values.) Viewing angle Wide Tele D30/D31 0 3FF D70/P 0 8D0 Wide end 3B4B 4000 Tele end 7AC0 Digital 18× The D70/P parameters that correspond to the Wide and the Tele end of the D30/D31 are approximately 0000h and 3B4Bh. However, at the Wide end, the horizontal viewing angles are 48.8˚ for the D30/D31, and 48.0˚ for the D70/P. Received parameters (0000h ~ 03FFh) will be converted within a range of 0000h to 3B4Bh. For D30/ D31 mode, the setting will normally be Digital Zoom OFF However, for CAM Zoom Tele/Wide commands and operations from the remote control, movement within the over all limits of the D70/P Zoom (0000h ~ 7AC0/ 77C0h) is possible. Cameras EVI-D30/D31 EVI-D70/P Parameters 1000h (FAR) to 9FFFh (NEAR, 1 cm) 1000h (FAR) to C000h (NEAR, 10 cm) Translation of commands Accepted parameters Translation Values less than 8400h Accepts as is Values greater than 8400h Translates to 8400h Because the range of the D70/P is narrower than that of the D30/D31, emulation is not carried out to match the actual focus position (focal point) to that of the D30/D31. The EVI-D70/P operational range of (1000h (FAR) ~ C000h (NEAR, 1cm)) is emulated within the operational range of the EVI-D30/D31 (1000h (FAR) ~ 9FFFh (NEAR, 1cm)). (Reference: Y = {(0xC000 - 0x1000)/(0x9FFF - 0x1000)}*(X - 0x1000) + 0x1000) Translation when answering inquiry commands Parameters Translation 1000h to 8400h Sends back parameters as is The D70/P returns D70/P parameters as-is. Reverse conversion is emulated as above. (Reference: X = {(0x9FFF- 0x1000)/(0xC000 - 0x1000)}*(Y - 0x1000) + 0x1000) 54
