EverAccess Proximity Readers, including the ERR-871, ERK-871 and ERM-871,
incorporate state-of-the-art technology, reliable performance, easy-to-use features, and
elegant appearance. The Readers generate a 125 kHz RF field that detects data from
proximity cards. The data output format is Wiegand 26 or RS-232, which allows easy
integration with most controllers, including EverAccess controllers. The Readers have
3 LED indicators which emit red, green, and yellow colors that indicate different values.
The pigtail wiring on the back of the Readers is 18” long, enabling easy installation.
EverAccess Proximity Readers are an ideal choice for any Access Control System.

EverAccess Proximity Readers should be installed by qualified installation
professionals. The installation procedures described below are recommended
guidelines, but all local, state, and national electrical codes take precedence.
Please refer to the following diagram for the wiring connections and mounting

Connection to Controller
Two options are available for data output: Wiegand 26 and a special RS232 format.
Both formats are compatible with EverAccess controllers, and Wiegand 26 is
compatible with many brand name controllers. Table 2.2 describes these two data
formats and their corresponding connection method in detail.
Please refer to Fig 2.1 to assist you with this portion of the installation. Fig. 2.1 (a), (b)
and (c) show the mounting steps for the regular reader, keypad reader and mullion
reader, respectively. The general rule is connecting the wires in the back of the reader
first. Take off the cover box from the reader, and fix the baseboard on the wall with
the screws (provided in the package) firmly (step 1). Then put the cover box of the
reader back on the baseboard (step 2, 3). Finally mount the screw at the bottom of the
reader (step 4. Both the screw and the spanner are provided in the package.)

Note: Please keep reader from large metal for at least 2.4". Two reader scan NOT
be installed side by side, or back to back with short distance. In case it is
required to install the reader side by side, a minimum distance of 6" is
recommended between readers. For the back-to-back case, the recommendation
distance is 8’” at least.

CHAPTER 3 DATA FORMAT

Data Format
This chapter will briefly introduce the format of reader’s output.
Two formats can be used to transfer data from the readers to controllers: specialized
RS-232 and wiegand 26. Specialized RS-232, specially designed for EverAccess system,
is recommended for use to achieve the best performance.
Specialized RS-232
The data speed of specialized RS-232 is 9600 bps. All data including card information
and keypad input has been combined together into a data packet. The data packet is
transferred as ASCII character codes.
The length of one data packet is 22 bytes totally, which contains 1-byte packet header,
1-byte synchronization information, 16-byte card information, 1-byte keypad input, 1byte tail (0x30) and 2-byte checksum. The last 2 bytes are the arithmetic checksum of
the previous 20 bytes data.
Each new data packet will be transferred repeatedly for 50 times. After that, a single
idle packet will be transmitted until some new data enters the system. The format of
the idle packet is similar to the normal data packet except that card information bytes
and keypad input bytes will be changed into 0x30, the same as the 1 byte packet tail.

Wiegand 26
As the name implies, each wiegand 26 packet contains 26 bit inside: 2 parity bits and
24-bit data. Please refer to Fig 3.2 for details. The 1
12 bits and the last bit (the 26
th
bit) is the odd parity of the 12-bit data before it

Unlike specialized RS-232 format, the keypad input is processed separately from the
card information. Each time the keypad is pressed, the data bus of Data 0 (green wire)
and Data 1 (brown wire) will send out a corresponding digit combination, as Table 3.1
shows:
