The Card Reader's DIP switches are used to set the machine type (washer or dryer) and the reader number that the card reader will display as.

These DIP Switches have ZERO affect on how the reader interacts with a machine, they only control what machine type and reader number the Card Reader displays as

The DIP Switches are located directly on the Card Reader circuit board (on the back of the reader board):

Dip Switch #1 sets the Machine Type (Down for Washer, Up for Dryer)
This dip switch's position is ONLY relevant for Card Readers being installed on Washers or Dryers;
all other Card Reader types will simply ignore DIP Switch #1's position.
Dip Switches #2 - #8 set the reader number using a binary system, which is documented at the bottom of this page.
You can number up to 127 washer readers, and 127 dryer readers, using these DIP switches.
The table below shows the switch positions, depending on the required machine/reader number.

Dip Switch Position Charts by Reader Machine Type

How to use the Card Reader number charts below

Click Washer Reader Numbers, Dryer Reader Numbers, or Other Reader Numbers to expand or collapse that section,
then click the number group to find the reader number you’re trying to set.

ON = the switch is set to its UP (ON) position
— = the switch is set to its DOWN (OFF) position
N/A = Switch #1 is ignored (DOOR, POS & SOAP/Vending machine readers)

Switch #1 only sets the machine type the reader will display as:
DOWN (OFF) = Washer reader
UP (ON) = Dryer reader.
Switch #1 is completely ignored when the reader is set as any other reader type (DOOR, POS, or SOAP/Vending machine, etc.)

Note for Numbering Stack Dryers:

Unlike single pocket dryers, on some stack dryers (like the Dexter C-Series and X-Series stack dryers), when numbering the readers you need to SKIP a reader number.

e.g. if you're numbering 2 Stack Dryers;

if you want the 1st stack to be Dryer #1, you would number that Card Reader as Dryer #1 using the DIP switches.
(the reader will then display the lower pocket of that dryer as Dryer #1, and the upper pocket as Dryer #2 automatically).

This means that when numbering the 2nd Dryer stack, you need to skip a number (skip Dryer #2),

so the next reader needs to be numbered as Dryer #3 using the DIP switches (NOT Dryer #2).
(this reader then displays the lower pocket as Dryer #3, and it's upper pocket as Dryer #4).

The reader installation guide for the specific model of machine you're working on will tell you if you need to skip a number when numbering the Dryer readers.
Most of the time, if only 1 reader is used to control both pockets on the same stack dryer (AND it's a SERIAL communication card reader), then usually you'll need to skip a number when numbering those readers so you don't end up with duplicate reader numbers.

Dip Switch Position Chart by Reader Number

The charts below contain the same information as the Charts by Reader Machine Types above.

The charts below simply show you how to set readers by number only.

The Chart below ONLY shows Dip Switches #2 - #8

as Dip Switch #1 is not used to determine the number a reader will display as:

Explanation of the math behind DIP switch (binary number system)

The right most switch (switch #8) is the least significant bit, with a value of 1 if it is in the upper position, and a value of 0 if in the lower position.
The 7th switch from the right (switch #2) is the most significant bit, with a value of 64 (2 raised to the power of 6) if in the upper position, and a value of zero in the lower position.

The machine number is simply the sum of the values of switches in the upper position.
So if the 8th and 7th switches are in the upper position, the number is 1+2=3.
If the 8th and 6th switches are in upper position, the machine number is 1+4=5.
