Overview
The TS-7553 was released Mar. 2010 and is a smaller form factor and cost reduced version of the TS-7552 without the extra USB ports and 8-28V switching power supply. It was designed to be mated with an inexpensive plastic enclosure and serve as a standalone general purpose embedded server.

Getting Started
Get a console
If you have a TS-9448, you can connect that to the 26 pin header and use the 10 pin header (labelled "Console") which will by default be the console port. If you do not have a TS-9448, you can hold the reset button for 5 seconds (until the red led lights up) and let go to switch the console port to the onboard COM port using the standard 8n1, no flow control, 115200 baud rate.
You can also telnet to the board with the default network configuration, though this will omit the TS-BOOTROM messages.
Busybox
After the board is first booted you will be at this shell:
Finished booting in 2.65 seconds Type 'tshelp' for help #
See the Busybox page on configuring the default boot options, including skipping Busybox. To boot into the full debian environment now, type 'exit' at the console.
Boot Process
This board uses the TS-BOOTROM to load the OS. The SD Boot jumper, as well as the TS-9448 will decide where the system boots.
Boot Selection With TS-9448
| Switch Pos. | SDBOOT Jumper | Boot Behavior |
|---|---|---|
| Down | Off | XNAND |
| None | On | Offboard SPI Flash |
| Up | Off | MicroSD |
Note: JP1 will cause the bootloader to only boot to SPI Flash
Boot Selection Without TS-9448
| SDBOOT Jumper | Boot Behavior |
|---|---|
| Off | XNAND |
| On | MicroSD |
Operating System
The operating system is common between all of the boards using the CNS2132. See the CNS2132 Software page for details about the debian distributions, software, busybox, and NAND image.
Connectors
26 Pin Header
TS-7552/TS-7553 also includes a .1" pin spacing external header for board to board interfacing. The external interfaces uses a total of 26 pins.

Product Notes
FCC Advisory
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A digital device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.
If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:
Reorient the receiving antenna. Relocate the unit with respect to the receiver. Plug the unit into a different outlet so that the unit and receiver are on different branch circuits. Ensure that mounting screws and connector attachment screws are tightly secured. Ensure that good quality, shielded, and grounded cables are used for all data communications. If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:
