Lantronix UDS 1100 freezing my software and hardware
I am using a lantronix UDS 1100 with its lantronix port redirector to convert an rs232 connection from a handscanner device to ethernet then receiving the data at a computer using some time and attendance software. i can connect to the scanner, and receive data from it using the software (novatime 2000)... when i try and rdownload handmaps from my computer to the scanner both the software and the scanner freeze up... the handmaps may be large data files and i think the obstruction is when the data goes through the lantronix device. what settings on the lantronix may be relevant? thanks

RS232 is now not being fitted to laptops This has become old technology. If you have devices that require connecting via an RS232 There are USB cables that emulate the connections of an RS232 that can be set to a com port to fool the device that it has the rightr connection. Look on Ebay there are quite a few at various prices, most from Hong Kong. I have bought aqnd used them to connect my radio scanners and Scancat software to program Amateur radios quite succesfully, as well as to run my old HP A3 scanner
I replaced my USB/Serial RS232 port adapter with a genuine RS232 serial port on the PC. THis solved the problem. Further reasearch on the net indicated that USB to RS232 - serial port converters do often have problems. I previously had not had a problem running on Windows XP and this is what alerted me to the possibility of the USB/RS232 port adapter as a possible reason for the "new" problem.
The UDS has the following LEDs, which help you diagnose problems. Power LED (green) Ethernet 10/100 Link (yellow = 10 Mb/green = 100 Mb) Ethernet Half/Full Duplex Activity (yellow = Half Duplex/green = Full Duplex) Diagnostic (red) Status (green) Simultaneously lit Diagnostic (red) and Status (green) LEDs mean something is wrong. If the Diagnostic LED is lit or blinking, count the number of times the Status LED blinks between its pauses. The following table explains the LED functions:
I purchased the Nikkai USB to RS232 adapter from Maplin and could not get the device working. (Maplin staff not much help!) The lead uses the Prolific PL-2303 device but Prolific do not supply the drivers to end users. However I found the drivers that appear to work at:
This then recognises the lead as a COM port. So far everything seems to work OK. (Null modem check and basic 9600 data transfer.)
First check the com port speed of computer port which you connected scanner .Com port speed should be 9600.
To change com port speed in computer go to computer/properties/device manager.
Select the ports eg com1 .Right click communication port go to properties and select port settings Bits per second should be 9600.
Serial scanner can not be test in word or note pad.you can download the RS232 software from below link and test the scanner http://www.lookrs232.com/
Try the LS100 from www.sena.com, it has a better warranty (5yrs vs 1yr) and its about half the price of a uds-10. We've had the same experience with the four UDS-10's we have and now 3 of the four have stopped working and report the following error: "FATAL ERROR 01/Setup memory: Contact tech support". I called there tech support and the guy (Marty) actully told me that the units have exceeded their life expectency. They all failed within the first ~22 months of operation. Working in a school district we cannot afford to keep doing the same thing over and over and over again, so our next project which involves 15 building will all use the SENA LS100 product and save the district money and have way better support and warranty. Thanks goes to "tech support" person Marty at Lantronix.
