Option Switches
Three sets of option switches are provided for module configuration. The module
must be power cycled or reset after these switches are set so that the options will
take effect. Table 2 describes the option switches and shows the factory defaults.

Table 2 - IIB Option Switches
The Group and Module selector switches are used to set the unit address during
module installation.
The unit address selector switch (OPTION switch position 4) is only used at
installation time. Refer to section 6, Special Installation Instructions, for a
description of this switch. For normal operation, this switch must be in the
DOWN position.
An IIB can monitor 8 receivers when the Link Fail feature is disabled or 7
receivers when the Link Fail feature is enabled (one receiver bank). Option
switches 1 through 3 allow the IIB to monitor any receiver bank supported by the
Comparator I/O Module. The settings for these switches is shown in Table 3. If
the Link Fail feature is enabled, the last receiver on an IIB is unusable. The IIB
will not provide monitoring and control functions for that receiver.
