CONFIGURATION

SB is completely configurable via the configuration file, SUPERB.INI. The file can be edited using

a text editor. It is loaded every time the SB application is started up. The file is divided into

sections with a format similar to Windows initializations files.

[SIZES] SECTION

The sizes section deals with the size of the SB application, such as number of connected MCs.

ComPorts

Depending on how many MCs are connected, one or more RS-422 serial ports are used for the

MC connections. If more than one port is used, a multiport adapter is installed in the SB host PC.

This entry specifies the number of ports used. Default is 1.

Controllers

This entry specifies the number of connected MCs. Default is 5.

Segments

If automatic file transfers is desired, this entry must have a non-zero value. It describes how

many file transfer segments that are to be active. In the default case of five MCs or less, this

value is normally four, since four different files are involved: N12, N13, F14 and F15. If more than

five MCs are connected each individual file must be divided up in segments, normally one

segment per five MCs. Default is calculated as

()

[]

Segments INT Controllers=⋅ +445/ ,

where INT is the integer part of the argument. See also SB Configuration for File Copy (page 12).

Default is 0, that is, no file transfer is enabled.

[IRQ] SECTION

This section deals with hardware and interrupt properties of the serial ports used for MC

communications. The ports are assumed to share one interrupt.

PortVector

This is the interrupt vector number for the port in hex. Use 0B for COM2 (default) or 0C for

COM1.

PIDMask

This is the mask word used for the Priority Interrupt Decoder interrupt request mask bit. Use 08

for COM2 (default) and 10 for COM1.

[PORTN] SECTIONS

SB communicates with MCs using a single COM port (COM 1..4) or using a multiport adapter.

The multiport adapter can have up to four serial ports, on different I/O addresses, and must share

a common IRQ line. This section specifies properties for the communication ports used for each

port. N can be 0, 1, 2 or 3, but must be less than the ComPorts entry in the [Sizes] Section, page

41.
