Legacy Stack Adapters
This page lists legacy or discontinued stack
adapters for SR 4 channel boards
For a list of the current SR stack adapters, please see the
Beagle SBC Product Selector
In the past, Symmetric Research offered a line of stack
accessories to make it easy to use our
USB4CH and
PAR4CH
A/D products with PC104 form factor motherboards whose small size makes them a
good match for many embedded systems, field boxes and portable applications.
PC104 motherboards are an older SBC form factor standard with a small 3.5" by
3.75" size which are now being superceded by the BBB SBC. Most
include non-standard connectors for common PC peripherals like disk
controllers, serial and parallel ports, but other features like video,
ethernet, modem, audio and digital IO vary widely across PC104 manufacturers.
We manufacture a
USB4CH-ADAPTER-PC104-KIT
adapter board for stacking the USB4CH and a PC104 SBC.
The example stack in the photo starts with a PC104 CPU card mounted on a
PAR4CH-PC104-ADAPTER. Below that is a
PAR4CH-PC104-DISK
board with a 2.5" hard disk. It's followed by a PAR4CH A/D board and has a
PAR4CH-PC104-POWER
power distribution panel on the bottom.
Click on the product names above to find out more about our 4CH/PC104
stack accessories. To find out more about standard PC104 products,
search the web for PC104 vendors.

PAR4CH/PC104 Thick Adapter |
 |
|
Product Description
The PAR4CH-PC104-ADAPTER-THICK is one of several accessory boards
for use in building a custom PAR4CH/PC104 stack. With its two sets of
mounting holes, this sturdy 1/8" thick adapter board makes it easy to
connect a PC104 CPU card to the PAR4CH. The outer set aligns with the
PAR4CH, while the inner aligns with the industry standard PC104 spec.
Mounting hardware for both the PAR4CH and the PC104 holes is
included.
The PAR4CH-PC104-ADAPTER-THICK and the
PAR4CH-PC104-ADAPTER both have
the same mounting hole configuration and large ground planes for
electrical noise suppression. The former is thicker and the latter has
additional headers for reducing ribbon cable twists if a compatible
PC104 CPU card is used.
Either adapter can be substituted at no charge for the standard
desktop enclosure included when purchasing a PAR4CH, just specify
which you prefer. Adapter boards may also be ordered separately.

Product Description
The PAR4CH-PC104-DISK is one of several accessory boards for use in
building a custom PAR4CH/PC104 stack. With its ribbon cable headers
and two sets of mounting holes, the disk mount board makes it easy to
add a standard 2.5" hard disk into a PAR4CH/PC104 equipment stack.
One set of mounting holes aligns with the PAR4CH and the other mounts
a standard 2.5" hard disk. Both 44 pin 2mm and 40 pin .1" ribbon cable
headers are provided to allow easy connections with various PC104 CPU
cards. An additional connector is included for bringing power to the
hard disk when using .1" cables. Plus, the PAR4CH-PC104-DISK has large
ground planes for good electrical noise suppression.
Also included on the board is a pair of connected 26 pin ribbon cable
headers. One has the 2mm spacing often found on PC104 CPU cards and
the other has the standard .1" spacing typically found on floppy drives,
providing a handy conversion between the two if needed.
