Introduction
EKI-1321P and EKI-1322P are programmable cellular gateways and users can program and debug owned codes in real-time to transparently bring RS-232/422/485 or Ethernet
devices to a cellular network. EKI-1321P and EKI-1322P GPRS IP Gateway's are compact, and can be DIN-rail or wall mounted and with both front panel and side panel LED displays
for easy identification. They come with dual DC power input from 12 to 48 V
DC
and have 2 KV EFT/Surge protection to prevent damage from various type of power resources. The
serial ports are also protected by 15 KV ESD line protection to keep your system safe from unexpected electrical discharges. Both models support dual SIM slots to support GPRS
signal redundancy to switch to an available channel automatically while the existing one is disconnected, and SD card slot for data buffering to prevent loss of serial data while the
communication is interrupted.
