Themis Computer
A.1.6.1 PS/2 and USB Protocols
Themis must be advised of whether you desire the PS/2 or USB protocol option at
the time the TA64 is ordered, since it requires the setting of multiple solder beads on
the TA64 at the factory before shipping (see Appendix B, “Jumper Pins and Solder
Beads”).
Table A-8
describes devices that are supported by each protocol, the solder
beads that must be set, and the adapter cable required.

Note:
It is possible to determine solder-bead settings by reading the appropriate
status registers in the Field-Programmable Gate Array (FPGA). Under BIOS, type
the command
dump-pld
at the
OK
prompt.
The setting of the DIN-8 connector as PS/2 or USB ports is given in bits [1..0] of
the FPGA register 0x08. See

, Chapter 4, Section 4.2 “FP-
GA Register Set”.
