Reference Notes:
• Power Supplies, Power Connectors, and Calculating Power Needs are topics that are discussed in the
DBK Basics section, which immediately follows this chapter.
• The chapter entitled, LBK and other non-DBK Options, discusses several non-DBK related options that
can be used with LogBook. These include COM/422/485, memory expansion, LBK1 remote terminal,
LBK2 Digital-to-Analog Output, and remote On/Off switch/LED indicator options.
• The DBK Option Cards & Modules User’s Manual (p/n 457-0905), details optional DBK cards and
modules and addresses DBK power issues. As a part of product support, the manual is automatically
loaded onto your hard drive during software installation. The default location is the Programs group,
which can be accessed throught the Windows desktop.
Expansion and Enhancement Options
A variety of cards and modules can be used to expand and enhance LogBook systems. These options are
found in three categories, LBK options, DBK options, and other. In addition to being discussed briefly
below, LBK options are detailed in the following chapter, and DBK options are detailed in the
DBK Option Cards & Modules User’s Manual (p/n 457-0901). The “other” options are detailed in this
chapter.
What are LBK Options?
LBK options are LogBook add-on features that can be used to enhance your system. The LBK options
described briefly below, and are detailed in the following chapter.
LBK/COM/422/485 , RS-232 Board with an RS-422/485 Option . The standard LogBook
communications board supports RS-232 only. However, the LogBook can be purchased with the
additional capability for RS-422 and RS-485. These optional boards (p/n LBK/COM/422/485) have
circuitry for all three communication protocols.
LBKMEM1 or LBKMEM1U , 16 MB DRAM Memory Expansion . The standard 4-MB RAM can be
user-replaced with a 16 MB board (LBK/MEM1-U). The expanded memory creates a larger data buffer,
allowing more time to swap PC-Cards. This is convenient when using fast scan rates. Note that the 16 MB
memory option can also be installed at the factory (LBK/MEM1).
LBK1 , Remote Terminal with LCD Screen. LBK1 provides a keypad to control the system’s basic
operation when no PC is attached and a LCD screen for viewing system status. A special rack (p/n
Mount1) is available to attach the
LBK1 to the top of LogBook. For applications in harsh environments, a
special enclosure can be used to shield the unit from water and thermal stress.
