LBK/COM/422/485 Option, Comparative Pinouts
LBK/MEM1-U, Expanded Memory (16 MB Upgrade)
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).
WARNING
Electric shock hazard. Turn off power to all system-connected devices prior to
connecting or disconnecting cables, or setting hardware configurations. Failure to
do so could result in electric shock or death, and equipment damage, even under
low-voltage conditions.
CAUTION
Perform the following procedure using ESD tools, containers, and procedures. One
or more related components are sensitive to damage from electrostatic discharge.
1. Turn off system power.
2. Remove LogBook’s top cover and locate SIMM socket CN5 (see figure). The CN5, 72-pin socket,
holds the RAM Memory Board.
3. Using ESD precautions, depress CN5’s two release clips and remove the 4-MB board.
4. Using ESD precautions, insert a 16 MB board (LBK/MEM1-U) into CN5. Note that the board and
socket are keyed to mate one-way-only, and will lock together when properly mated.
5. Replace the top cover and screws.
6. Turn on system power.
Note:
The CN5 slot has two release
clips that must be depressed to
release the memory card.
The LBK/MEM1-U Memory
Board inserts into the CN5 slot
on LogBook’s Motherboard.
