Appendix
TAP Commands Table
These commands are used to control the TA-1 amplifier. You will need to configure your IBM
compatible PC for a hyperterminal session as outlined earlier in the appendix. You will also need
to construct a TAP cable using the instructions on the previous page.
Command Format
Command: single ASCII character (case sensitive)
Argument: 0-5 ASCII characters, command dependant
Delimiter: <CR>
Serial Commands to the TA-1 amplifier

IC0 acts the same way
as VOLUME UP
command from the IR
receiver. See the IR

01 is the dB of output
attenuation. Use any
number between 01
and 80. 01 is max
volume. 80 is
minimum.
Bypass
RS232 code

are valid
Connects
RS232 port to

serial port with
software
Enables direct
communication with the
DSP PCB. The only
way to resume normal
operation: send ‘Ctrl-s’
for software restart.
Pass

the DSP
PCB
P c C = any ASCII
character
Pass the ASCII
parameter to
the DSP PCB
p<CR> will send a CD
(==0x0D) to the DSP
PCB.
pA<CR> will pass ‘A’ to
the DSP PCB.

Disable
C p P = 0,1 Enables or
disables Echo
C1<CR> = Echo
enabled (default)
C0<CR> = Echo
disabled
