1Infinity Usb Unlimited Readme 2----------------------------- 3 4Hi all, 5 6 7This module provide a serial interface to use your 8IUU unit in phoenix mode. Loading this module will 9bring a ttyUSB[0-x] interface. This driver must be 10used by your favorite application to pilot the IUU 11 12This driver is still in beta stage, so bugs can 13occur and your system may freeze. As far I now, 14I never had any problem with it, but I'm not a real 15guru, so don't blame me if your system is unstable 16 17You can plug more than one IUU. Every unit will 18have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...) 19 20 21 22How to tune the reader speed ? 23 24 A few parameters can be used at load time 25 To use parameters, just unload the module if it is 26 already loaded and use modprobe iuu_phoenix param=value. 27 In case of prebuilt module, use the command 28 insmod iuu_phoenix param=value. 29 30 Example: 31 32 modprobe iuu_phoenix clockmode=3 33 34 The parameters are: 35 36 parm: clockmode:1=3Mhz579,2=3Mhz680,3=6Mhz (int) 37 parm: boost:overclock boost percent 100 to 500 (int) 38 parm: cdmode:Card detect mode 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int) 39 parm: xmas:xmas color enabled or not (bool) 40 parm: debug:Debug enabled or not (bool) 41 42- clockmode will provide 3 different base settings commonly adopted by 43 different software: 44 1. 3Mhz579 45 2. 3Mhz680 46 3. 6Mhz 47 48- boost provide a way to overclock the reader ( my favorite :-) ) 49 For example to have best performance than a simple clockmode=3, try this: 50 51 modprobe boost=195 52 53 This will put the reader in a base of 3Mhz579 but boosted a 195 % ! 54 the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase 55 the speed to a score 10 to 20% better than the simple clockmode=3 !!! 56 57 58- cdmode permit to setup the signal used to inform the userland ( ioctl answer ) 59 if the card is present or not. Eight signals are possible. 60 61- xmas is completely useless except for your eyes. This is one of my friend who was 62 so sad to have a nice device like the iuu without seeing all color range available. 63 So I have added this option to permit him to see a lot of color ( each activity change the color 64 and the frequency randomly ) 65 66- debug will produce a lot of debugging messages... 67 68 69 Last notes: 70 71 Don't worry about the serial settings, the serial emulation 72 is an abstraction, so use any speed or parity setting will 73 work. ( This will not change anything ).Later I will perhaps 74 use this settings to deduce de boost but is that feature 75 really necessary ? 76 The autodetect feature used is the serial CD. If that doesn't 77 work for your software, disable detection mechanism in it. 78 79 80 Have fun ! 81 82 Alain Degreffe 83 84 eczema(at)ecze.com 85
