VII. Programming
A. Hardware
The programming hardware is located on the right-hand side of the circuit board, and consists of Tone Select pushbutton S1, eight-position DIP
switch S2 and a row of twenty LED's, identified with the numbers 450 through 1950 (EIA Tone LED’s) and the letters A through D (ABCD
LED’s). Functions of the individual S2 DIP switch sections are as follows:
OFF OFF OFF OFF OFF OFF OFF OFF
ON ON ON ON ON ON ON ON

B. Options
The TTP200 is programmed by selecting a pre-programmed "EIA Tone-to-Output" assignment pattern, or "Pre-Set." Pre-Sets are available for
several different output options:
1. Discrete 1 of 5 Outputs
Pre-Sets 1 through x assign the 16 standard EIA tones to activate one, and only one, of the "Fx" outputs at a time.
2. Discrete "Split" Outputs
Pre-Sets x though y split the five "Fx" outputs into two groups, one containing “ 1 of 3” outputs F1 through F3 and the other containing “1 of 2”
outputs F4 and F5.
3. Discrete "Wildcard" Outputs
Pre-Sets x though y establish outputs F1 through F4 as discrete outputs and use F5 as a "wild card" output that toggles independently of the other
outputs.
4. BCD Output
Pre-Sets x through y produce a BCD output based on the 16 EIA tones.
5. Customized Output
Once a Pre-Set has been loaded, it can be customized by manually re-programming some or all of the individual EIA Tone-to-Output
assignments. Blank Pre-Sets are provided for each of the four output types (three discrete and one binary) to facilitate building up custom EIA
Tone-to-Output assignments "from scratch."
6. Inverted Output
Leaving S2-2 (F1) ON during normal operation inverts the "Fx" outputs.

3. To Check the Existing Program:
OFF OFF OFF OFF OFF OFF OFF
8 7 6 5 4 3 2 1
Y X F5 F4 F3 F2 F1 PROG
a. Turn the PROG switch ON.
b. During the first three seconds, the ABCD LED’s indicate the number of the currently loaded Pre-Set in binary form. This indication
flashes if the PRE-Set has been customized.
c. After the ABCD LED’s go out, switches F1 through F5 can be used to select a specific output to be checked.
d. The front panel LED's and the EIA Tone LED's indicate individual EIA Tone-to-Output assignment of the selected Output.
e. Normal operation resumes when all switches are returned to the OFF position. The existing settings are not modified.
4. To Load a Pre-Set:
OFF OFF OFF OFF OFF OFF
ON ON ON ON ON ON
ON ON
8 7 6 5 4 3 2 1
Y X F5 F4 F3 F2 F1 PROG
a. Turn the X switch ON.
b. Turn the PROG switch ON.
c. The ABCD LED's indicate Pre-Set number in binary form, starting with 0001.
d. Use the Tone Select pushbutton to step through the Pre-Sets. Press and release the Tone Select pushbutton to advance to the next
Pre-Set. Stop when the number of the desired Pre-Set is indicated in binary form on the ABCD LED’s.
e. To complete loading of the Pre-Set:
i. Turn the X switch OFF.*
ii. Turn the PROG switch OFF.*
The TTP200 will then return to normal operation.
*Turning the PROG switch OFF before turning the X switch OFF exits the Load function without saving the new Pre-Set.
Example: Loading Pre-Set #3
a. Turn the X switch ON.
b. Turn the PROG switch ON.
c. Press and release the Tone Select pushbutton until the ABCD LED’s indicate the number “3” in binary form, that is,
LED A = ON
LED B = ON
LED C = OFF
LED D = OFF.
d. Turn the X switch OFF.
e. Turn the PROG switch OFF.
f. The TTP200 is now ready for use.
