HSP-EVAL
The Parallel Port Bus is interfaced to the PC by connecting
the provided ribbon cable between the 26 position shrouded
header (J5) and the PC's parallel port. The ribbon cable
maps the Parallel Port Bus signals to the PC's parallel port
as shown in Table 6.
The Parallel Port Bus is brought out through each of the 96
Pin DIN connectors (P1, P2) so that Multiple HSP-EVALs
can be daisy chained. This allows different HSP-EVALs in
the chain to be controlled through a single HSP-EVAL which
has been connected to a host PC.
Register Structure
The HSP-EVAL provides a series of registers which may be
used as a source for daughter board input and control. In
addition, a Shift Register is supplied to serialize data on the
daughter board output bus for transmission via the Parallel
Port Bus. Data transfers involving these registers are
described in the following sections.
The HSP-EVAL has a set of eight 8-bit data registers which
are organized as a set of four “logical” input and control
registers, Input Registers 1 thru 3 and the CTL Control
Register. The outputs of these registers drive four 16 bit
busses which are mapped to the daughter board through the
Input Connector (J1) and the Control Connector (J3) (see
Bus Structure Section). The mapping of the 8-bit data
registers to bus signals and “logical” registers is given in
Table 7.
