Symmetric Research offers offers a line of PC104 accessories to assist in building custom stacks using our A/D products.

PC104 form factor motherboards are well established and popular because their small size makes them a good match for many field boxes and portable applications.

The PAR4CH/PC104 accessories we offer include adapters making it easy to connect a PAR4CH, to connect 2.5" hard disks, and to distribute power with clean wiring to the entire stack. All these boards are the same size as the PAR4CH.

The example PAR4CH/PC104 stack shown in the photo above starts with a PC104 CPU card at the top mounted on a PAR4CH-PC104-ADAPTER. Below that is a PAR4CH-PC104-DISK board with a 30 GB 2.5" hard disk. It's followed by a PAR4CH 4 channel 24 bit A/D board and has a PAR4CH-PC104-POWER power distribution panel on the bottom.

Some of the benefits we see with PC104 systems are described below. More information can also be found on our Mini ITX & PC104 FAQ page.

Small Size: At 3.5" by 3.75", the PC104 standard is one of the smallest PC motherboard form factors to enjoy wide popularity. Most PC104 CPU cards include connectors for PC peripherals like disk controllers, serial and parallel ports, and etc. The features available across PC104 motherboard manufacturers varies widely.

Expansion: The PC104 expansion bus uses the same signals as the 8 and 16 bit ISA bus formerly used on desktop PCs. Many equipment manufactures have moved their ISA designs to the PC104 standard, offering all sort of add-ons such as video, ethernet, modem, audio, digital IO, and etc.
