* using firmware update is on customers risk (no warranty).
** connect RIP-Pin (Pin 5 to ground). Then cycle power. After restart, the Scanner will communicate on the default
IP address. Set new IP address using MEL-Demo-Software Rev.2.0.4.2, Tab 11. Release RIP-Pin from ground.
Cycle power. Now the new IP-address is active. For alternative method see also page 24.
*** ground should be applied in a central place at machine side. Avoid ground loops, connect ground leads in a
“star” structure. Connect protective ground in central place to the machine, connect the case with short leads.
Bridges for simulated RS-232 hardware handshake
Bridge 1: pins 1 – 4 -6
Bridge 2: 7 – 8 Connect Case of D-Sub-9Pin connector to Pin 5 (GND).

The enclosure of the D-Sub connector is wired with a
short lead to bridge 1-14. The Ethernet cable shield is
connected with a short lead to the bridge 1-14.
Pin 8 is not connected.
