Mercury4e Specification Sheet v1.3
1. Introduction
The Mercury4e™ is ThingMagic’s entry in the embedded reader market, which comprises
label printers, label applicators, and handheld terminals. Unlike previous members of
ThingMagic’s Mercury family, the Mercury4e™ readers are designed for embedded
applications within a host system. They interface with a host system via asynchronous serial
(TTL-level RS-232) using a packetized polled mode communication. Anti-collision
capability is not provided in the initial release of the Mercury4e product.
Mercury4e™ readers have a single on-board processor, a TI 55xx series DSP. The reader
operates in a single-tasking, streaming mode where tag IDs are sent back to the host
processor one-at-a-time, in a mode suitable for small tag populations where reading occurs
primarily when triggered by the host system. This is envisioned to occur in response to the
host system’s request when a label is aligned beneath the print head in a printer application.

5.5cm x 9cm x 1.5cm
Host-switched multi-protocol:
EPC Global Class 0 (including Symbol and Impinj Class 0+ R/W)
EPC Class 1 R/W (64 and 96 bit silicon)
EPC Generation 2 R/W*
ISO18000-6B R/W
902-928 MHz, for FHSS use and certification in the US and
Canada
Read/write rate and range is protocol dependent and will vary
depending on RF signal strength and other environmental factors.
2 MMCX connectors for two antennas. Unit will tolerate 2:1
VSWR without damage, but a VSWR below 1.5:1 will be needed
for best performance. Circular polarization is supported.
Fixed 5.3 VDC +/- 4% DC supply voltage, average power
dependent on duty cycle. Peak power not more than 8.8W. Power
supply ripple and noise must be less than 100mV pp, and the host
power supply load transient response must support a dI/dT of
500kA/s with less than 100mV over/undershoot.
RF Power
Output
3/17/2006 ThingMagic 3/7
RF power output depends on available peak supply current. RF
output power is variable in 0.1dB steps from 20dBm to 24dBm.
Absolute accuracy of RF output power is +/- 1dB.
