Most of the FD-40 settings have to be carried out by FD-Tool, a PC based configuration
software, either on-line or off-line. Only RS-232 or RS-485 transfer settings will be set by
DIP switches.
6.4.1 DIP switch settings
DIP-switches are accessible under the lid on top of the unit.
Warning! Prevent damage to internal electronics from electrostatic discharges
(ESD)
by discharging your body to a grounding point (e.g. use of wrist
strap), before the lid on top of the modem is removed.
Warning! Do not open connected equipment.
Prevent access to hazardous voltages by disconnecting the unit from
AC/DC mains supply and all other electrical connections.
NOTE The change of DIP switch settings are valid only after a power on.
