O - DIP S
N BOARD
The H2TU-C circuit board has an 8-position DIP switch, S2 (see
through the DIP switch cannot be configured through the maintenance terminal screens. Configuration
information for the switches is reported on the screens, but is "read only." OFF is the default setting of all switches.
Table 2 describes the functions of DIP switch S2.
DIP switch S2 is the only means by which the options it controls can be set. The maintenance
terminal screens showing these option settings are read-only.
