Thinking about the LI
I was thinking about the new gun Roy was testing the LTI 20/20 and how cheap it is and Cali is getting them (DJ maybe you are lucky to have the Zr4 now). If the LI is vulnerable to this gun what is the turnaround to get this gun covered in an update for the LI.
This gun might be a real cheap option for police departments, plus the LTI brand seems so be somewhat popular already.
I think you can update your control box on your own PC now... correct me if I am wrong but that is one of the big selling points of LI if it is.Originally Posted by focalcivic
The firmware upgrading is still a work in progress..
Odd how Cliff is quiet on this one.......
A while ago Cliff told me the firmware could not be upgraded by the user. The user can change only settings (like sun interference alerts) by using an RS232 interface to a PC with the L.I. software.
To upgrade for a new laser gun, you have to send the cpu box back to L.I.
Where do you get a RS232 interface anyway? and how do you plug it to the computer, via conversion to a USB?
I dont believe you can use a usb conversion..I know the upgrades are not able to be done by users...The user pays a small deposit and then LI ships a new cpu to owner with upgraded software. When the owner recieves new cpu he send old one back and deposit is refunded.
The RS232 port is the one commonly used for external modems. Not many modern PC's have them anymore as the modem is built in and a telephone jack has replaced the RS232 port.
There are USB to RS232 converter cables, but you need to make sure the one you get has a FTDI chip inside otherwise it won't work. Another problem is that RS232 connectors and ports come in two flavors (DB 25 or DB 9 (for the number of pins and the shape)), plus some cables are configured straight through, some are null modems, some don't connect all the pins, etc. etc..
Again - you cannot upgrade the firmware even with an RS232 port and the proper cable/connectors - with the proper L.I. software you could only change certain optional settings that are already in the firmware. to change the firmware you have to send it back.
Cliff said they have talked about making them so a user can flash them but that would be in the future.
So this port is almost useless LOL. I don't think the LI comes with any cables right?
Why do you say the port is useless? Granted you cannot update the firmware, but I have not read that you can do that for any other jammer either.
I also don't know what settings you can set with or without a PC on an L.I. or any other, but at least with the software you can set certain settings on the L.I.
RS232 cables are a dime a dozen or were the last time I got some. I suppose since they are obsolete they might now be more expensive. Fortunately I have a lifetime supply of all various configurations, not including the many I already hrew out.
The USB to RS232 converter cable with the needed chip might be more expensive - I have not checked.
