RM6-A Data Modem & ALE – 3, 6 kHz
The RM6-A is a high data rate LF and HF data modem and ALE controller for standards-based BLOS naval and strategic data communications. The RM6-A supports MIL-STD-188-110A/B, STANAG 4539 and related modems and MIL-STD-188-141, App A (2G ALE) and App B (Linking Protection). The RM6-A is a replacement of the RM6 modem and it is recommended for new systems.
The RM6-A shares its interface layout with the newer RM8 and RM8 wideband modems. The RM6-A supports the RAP1/RIPC and STANAG 5066 Annex E (ASCII) control protocols.
The RM6-A is suitable for long-distance (up to 10 000 km) point-to-point data communications. The unit offers a built-in 2G ALE controller option. The RM6-A is recommended as an alternative to the RM6 for new installations.
The RM6-A is based on the latest generation hardware and software. The RM6-A matches the form and fit of the RM8.
The maximum data rate is 9600 bps over a standard 3 kHz (SSB) HF radio channel and 19200 bps over an ISB channel.
The RM6 is designed to operate in conjunction with an external STANAG 5066 ARQ server. The unit is intended for installation into 19-inch rack systems or to be used as a desktop unit. The front panel (LCD display and keypad) provides full local control of all settings and functions.
