SCOPE
This document describes the interface aspects of the of SG-20 Discovery with WLAN (and
Ethernet) communication feature (Scantech P/N A3601171) and is complementary to the
Discovery User’s Manual. Please follow all installation instructions as mentioned there.
The SG-20 WLAN is provided with a converter module which lifts the standard Discovery
communication to WLAN (802.11B/G) and 10/100 Ethernet interfaces. The supported
protocols are ARP, UDP, TCP/IP, ICMP, Telnet, TFTP, DHCP, HTTP, SNMP, and BOOTP.
This manual refers to Discovery firmware PRD043 and higher.
The Discovery with WiFi interface supports 802.11 B and G and offers 64/128bit WEP and WPA
encryption, as of Discovery hardware version P/N A3601174x (November 2006).
Note that the Discovery itself uses RS232 to communicate with the WLAN module.
So be careful when modifying any RS232 settings of either the Discovery SG20
or WLAN module.
DISCOVERY ETHERNET USERS
