The SD62 wireless base station provides a secure encrypted connection between the host and up to seven Intermec Bluetooth® handheld scanners-including SR61B, SF61B and SG20B. With no need to install special software, the SD62 can be quickly installed to support your wireless data capture needs in an instant. Communication between the SD62 and associated scanners is bi-directional: it checks that bar code data is fully transmitted to the host. If the data is not transmitted for any reason--for example, if the host PC is turned off--the module sends an error beep back to the scanner. This error-checking capability provides assurance to the operator that bar code data was transmitted successfully.
