Master board. HSL is a master-slave communication system. In
host side, we call the control board as master board.

Slave module. HSL is a master-slave communication system. In
remote side, the slave module can connect a variety of sensors.

Slave index. The basic unit in HSL system. One HSL slave mod-
ule may occupy 1, 2 or 4 slave indexes. This depends on the
design of slave modules.

Full duplex. Data transmission and receiving at the same scan-
ning time.

Half duplex. Data transmission and receiving at the consecutive
scanning time.

HSL master controller. One HSL ASIC plays the role of master
controller. For example, PCI-7853 has one on-board HSL ASIC; it
can connect a maximum of 63 slave indexes. For convenient con-
nection, the HSL master has two ports. Using the same technol-
ogy, the PCI-7854 can connect a maximum 126 slave indexes and
has four ports.

Transmission speed. The data speed is between master board
and slave modules. The unit is bit per second.
