The REI-8 II is intended for use in the harsh environments of shipboard applications and can be used both indoors or outdoors. The REI-8 II user console features an 8 inch widescreen display coupled with a SDAP (secure digital audio processor) module. The REI-8 II connects to the MVP switch over an IP network to both a red and black voice network. It is TEMPEST/1-13 certified to maintain isolation between them. The console is designed for IP67 waterproofing, and has also been designed for MIL-S-901D shock and MILSTD-167 vibration. The resistive touchscreen provides fast and accurate touch response and has a mounting pattern for legacy shipboard use. The REI-8 II features two headset/handset ports, a front panel PTT button and microphone, status LEDs, two tactile digital rotary controls for selection and volume adjustment, an internal speaker, a footswitch connection, and input/output audio jacks. Each unit can display 10 private pages and 250 shared pages of line keys. Each page can be customized with a background image (map, ops floor layout, etc.) and augmented with text, color panels, and additional images (emblems, checklists, phone lists, etc.). Conference line keys can be placed anywhere on the page and are not confined to a grid. The REI-8 II also provides up to 35 user-configurable function buttons.
