IHZ4 vs IHZ4N: two 4-port UHF fixed readers compared

The IHZ4 and the IHZ4N share the same aluminium housing (170 × 120 × 25 mm), four SMA antenna ports and 0–33 dBm output power, adjustable in 1 dB steps, and both come in a version for India's 865–868 MHz band. They differ inside. The IHZ4 is built on the E710 reader chip with Gen2X support, reads up to 1,000 tags/s, and lists RJ45, RS-232, RS-485, Wiegand and USB 2.0 with 3 inputs and 3 relay outputs. The IHZ4N uses an N704 4-port module, reads more than 400 tags/s, and lists Ethernet, RS-232 and RS-485, with Wiegand on request, and 2 inputs with 2 relay outputs.
