Level
Control
The program in the CD called “treslevel.exe” is a handy utility that allows you to control the
output power of the Reader. What this means is if you are getting 30’ read range but only want
15’, then change the Output Level from 30.0 dBm to 20.0 dBm. Once installed you connect
your Reader to the PC via RS232 port and run this program.
