On the module is a 5x3 grid of dots, either turned on or off, a screen below it containing a 6-letter word, and several formations of 7 dots surrounding it all.

Note down the grid’s state (referred to as the Canvas) as well as the given word (referred to as the Keyword).

A series of 5 different pseudo-Ciphers (R, I, S, E, D) will be employed one after another to decrypt the final grid pattern. Which order the Ciphers are applied in depends on edgework:

• Order all five Ciphers based on the amount of edgework present, from highest to lowest:
• Cipher R uses number of unlit indicators.
• Cipher I uses number of Serial Number digits.
• Cipher S uses number of lit indicators.
• Cipher E uses number of batteries.
• Cipher D uses number of port plates.
• In case of a tie, order the tied ones in the order R, I, S, E, D.

Apply all five Ciphers in the order obtained above.

After all five Ciphers have been applied, you should end up with one of the following five patterns formed of 7 dots, found on the module’s casing:

Press the pattern on the module’s casing to solve the module.

Here is the location for each light in the Canvas, as a reference for later steps:

A1	B1	C1	D1	E1
A2	B2	C2	D2	E2
A3	B3	C3	D3	E3

Cipher R:

Take the Keyword on the bottom screen.

For each letter, if it is within the range A-M, replace it with an OFF light; or an ON light if it is within the range N-Z.

Convert this 6-light sequence into a 2x3 vertical rectangle (in reading order) and replace a side of the Canvas with this newly-obtained shape.

If there is at least 1 indicator containing a letter from “EGIR”, replace the leftmost side of the Canvas (columns A-B); otherwise replace the rightmost side of the Canvas (columns D-E).

Cipher I:

Take the 5x3 representation of the Canvas below.

Move each numbered light to the next one in ascending numerical order (wrapping 8 to 1).
The light in position #1 should end up in position #2; #2 in the position of #3, etc. until #8 ends up at position #1.

1	.	5	.	4
6	.	.	.	7
.	2	8	3	.

Cipher S:

Treat each row of your current Canvas as Binary, taking ON as a 1 and OFF as a 0; and convert it to a number in the range 0-31.

For each row:

• Multiply the number by 5.
• Mod the number by 32 (repeatedly subtract 32 until the result is within the range 0-31).
• Convert back the number into Binary and set it as the new row’s content in your Canvas.

0	00000	8	01000	16	10000	24	11000
1	00001	9	01001	17	10001	25	11001
2	00010	10	01010	18	10010	26	11010
3	00011	11	01011	19	10011	27	11011
4	00100	12	01100	20	10100	28	11100
5	00101	13	01101	21	10101	29	11101
6	00110	14	01110	22	10110	30	11110
7	00111	15	01111	23	10111	31	11111

Cipher E:

Take the 5x3 representation of the Canvas below.

For each space marked with an X, invert the state of the light in your Canvas.

You can also think of this as XORing your Canvas with the Canvas provided below.

.	.	X	.	.
.	X	X	X	.
X	.	X	.	X

Cipher D:

Cipher D becomes more powerful the earlier it is applied.

If Cipher D is the first Cipher you apply, do all five steps below.
If it is the second one you apply, do the first four steps only.
If it is the third one you apply, do the first three steps only.
If it is the fourth one you apply, do the first two steps only.
If it is the last one you apply, do the first step only.

• Step 1: Take the outer 12 lights of the Canvas (excluding the center 3x1 rectangle). Cycle the lights clockwise thrice, so that A1 ends up at D1, A3 becomes B1, E2 becomes C3, etc.
• Step 2: For each light in the second row, shift them to the right the same number of times as the number of steps you will do in Cipher D, looping back (shift right 4 times if Cipher D is the second to apply, etc).
• Step 3: Take the 5x3 representation of the Canvas below.
  For each space marked with an X, invert the state of the light in your Canvas.
  You can also think of this as XORing your Canvas with the Canvas provided below.
  

  .	X	X	X	.
  X	.	.	.	X
  .	X	X	X	.

• Step 4: Rotate the center 3x3 square (the 9 tiles in the center, the columns B-C-D) a total of 180°.
• Step 5: Do the opposite cycle you did in Step 1: counterclockwise thrice, so that D1 becomes A1, B1 becomes A3, and C3 becomes E2.
