Reader DIP Switch settings

The reader's DIP switches are used to set the machine type (washer or dryer) and the number for the card reader.

The DIP switch is located directly on the card reader circuit board:

Dip Switch #1 sets the Machine Type (Down for Washer, Up for Dryer)

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.

Note for reader's that are NOT installed on a Washer or Dryer:

If the reader you are numbering is NOT for a washer or dryer (e.g. vending machine (SOAP), DOOR, or POS reader);

Switch #1 is ignored, and therefore it does not matter what position it is in.

(these reader types are pre-programmed in advanced for the specific type of equipment it is controlling)

HOWEVER for these type of readers, you'll still need to set the reader's number using Dip Switches #2 - #8

Note for Numbering Stack Dryers:

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

e.g. if you're numbering 2 Stack Dryers, and you want the 1st stack to be Dryer #1, you would number the 1st 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).

Then when numbering the 2nd Dryer stack, you need to skip a number, so the next reader needs to be numbered as Dryer #3 using the DIP switches (NOT Dryer #2).
(the reader then displays the lower pocket as Dryer #3, and upper pocket as Dryer #4).

The reader installation guide for the specific model of machine will tell you if you need to skip a number when numbering the readers.
Most of the time, if only 1 reader is used to control both pockets on a stack dryer, then usually you need to skip a number when numbering those readers

Dip Switch Position Chart for Reader Numbering

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

Dip Switch #1 is not shown below because it is not used to number the reader

For readers on equipment that are not laundry machines (e.g soap dispensers), the position of switch 1 does not matter.

Explanation of the math behind DIP switch
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 1st and 2nd switches are in the upper position, the number is 1+2=3. If the 1st and 3rd switches are in upper position, the machine number is 1+4=5. If the 2nd and 4th switches are in the upper position, the machine number is 2+8=10.
