SmartPass 4 (Encompass 4) RF Reader


The TransCore SmartPass 4 (Encompass 4 ATA) Reader  replaces both the AI1620-110 Low Power SmartPass and the AI1620-114 High Power SmartPass Readers.  It is upward compatible with both readers.  The SmartPass 4 allows the user to adjust the output power

The SmartPass 4 reader is used to read railroad AT5110, AT5118, AT5125, AT5133, AT5510, AT5541 and AT5549 transportation tags.  It will also read AT5102, AT5105, AT5106, AT5107, AT5112, AT5114, AT5146 and AT5147 access control tags. This unit contains an RF module, tag decoder, and power supply in a single module.

This reader can read rail car AEI tags at speeds of up to 60 mph.

The SmartPass 4 reader can be ordered with either an RS-232 or RS-422 serial interface.  This makes it very easy to interface to almost any computer.

The part numbers for SmartPass reader with the internal antenna are 10-4002-008 for the RS-232 interface and 10-4004-008 for the RS-422 interface.


When the SmartPass Reader reads a tag, it translates the 120 bits of data encoded in the tag into twenty six-bit alpha/numeric characters.  This text string is terminated with a carriage return and a line feed character and then sent to the computer over the serial interface.  With this simple interface, programs such as Windows's HyperTerminal can be used to view tag data and send commands to the SmartPass reader.


The input power is either 16 to 20 VAC (at 47 to 63 Hz) or 16 to 28 VDC.


We typically stock the SmartPass 4 readers that have the internal antenna.  We do not stock the SmartPass 4 readers that have the external antenna option.  Normal delivery on these are 6 to 8 weeks and are $500 higher in price.
