Module Design:
Compact Eurostandard modular design. Plug-in modules mate with Daniels
standard MT-3 repeater subrack. Subracks and modules comply with IEEE 1101,
DIN 41494 and IEC 297-3 (mechanical size / modular arrangement).
standard MT-3 repeater subrack. Subracks and modules comply with IEEE 1101,
DIN 41494 and IEC 297-3 (mechanical size / modular arrangement).
External Connections:
RF Connection: Type N connector located on the transmitter module front panel.
Motherboard Connections (Audio, Power, and Control) are made through a 48 pin,
gold plated, type F connector on the rear of the transmitter module. User
connection is made through a mated “mother board” assembly of the repeater
subrack. Type F standard connector complies with DIN 41612 Level 2 (200 mating
cycles, 4 day 10 ppm SO2 gas test with no functional impairment and no change
in contact resistance).
