Ordering Information
All e*Tag® reader/writers meet ISO 15693 and 14443A standards. The product series is designated as “ET4-”, followed by letters that designate the communications and housing specifications of the product.

The following communication methods are available:
X” = RS-485 communications (supports multiple readers on a twisted pair bus).
R” = RS-232 communications.
W” = Wiegand communications (commonly used for access control systems).
T” = TTL (transistor-transistor logic) communications.
Some e*Tag® models combine two communication methods, i.e. WX (Wiegand and RS-485).

There are currently four form factors of the e*Tag®reader/writer:
M” = Mini housing (approx. 1.5" x 3.5"), with integral antenna, potted for moisture and dust resistance.
S” = Switchplate housing (approx. 3.25" x 4.5"), with integral antenna, potted for moisture and dust
E” = Board only, with 10-pin connector for remote 50-ohm antenna (No or buzzer).
N” = Board only, with SMA coaxial connector for 50-ohm antenna (not available with RS-232), LED and
