M2115RCU-S

Steel NEMA4 Enclosure

The M2115RCU is a versatile, economical VHF-based radio control solution for hangar doors, gates, and other airfield applications where certification to FAA AC 150/5345-49C is not required.

• Less Expensive, MORE FEATURES! Versatile unit provides unattended, all weather, air-to-ground radio control to operate hanger doors, control approach and runway end lights, taxi lights, or any other application where remote operation is desired from inside the aircraft.
• Resume On Power Loss Automatically energizes the same relays that were on when the power was lost significantly increasing flight crew safety especially in remote airfield locations.
• Synthesized Tuning - No more Crystals! Customer programmable. Utilizing a standard DB-9 serial cable (included) use your PC to program the operating frequency and adjust sensitivity using custom PC software. Password required to change operating frequency for increased security.
• Multiple Configuration Options Can be configured for one, two or three relays. Has an 8 position DIP switch for setting configuration options. Operates like the older M15RCU unit. Same 3, 5 and 7 clicks to activate individual relays.
• Indications. LEDs light up to display relay activation. A STATUS LED flashes to indicate normal operation. WINDOW LED indicates detection of a mic click.
• Operates from any Available Power Source -Power from 9VDC, 12VDC, 24VDC, 30VDC, 115VAC, or from a solar panel with a battery back-up system for longer life and minimum maintenance.
• 8 Different Time Out Values - No timeouts, 10 seconds (used for testing units), 5, 10, 15, 30, 45 & 60 minutes. Available in 8 and 12 hour timeouts intervals upon special request.
• Test Button - Test controller circuits without radio inputs. Reset button resets relay after test.

• Dimensions: 7.5" wide 4.5" high 2" deep excluding hardware
• Case Type: NEMA4 steel.
• Power Required: 10 to 30 VDC (negative ground) 0.30 amp maximum or - 120 / 240 VAC +/-15% jumper selected at the factory (50 / 25 mA AC).
• Recommended Protection: 1/8A / 250V for controller / radio. 5A for relay contacts. Choose between Fuse and Circuit breakers when ordering. Optional AC line and antenna lightning protection.
• Temperature range: -20° F to +122° F (-30° C to +50° C)
• Humidity: 95% non-condensing

• Antenna: SO-239 (UHF) 50 ohms with optional lightning protection (replaceable cartridge)
• Frequency Range: 118.000 to 136.975 MHz
• Channel Spacing: 25 KHz or 8.333 KHz
• Sensitivity: 5 uv 30% mod. at 1 KHz gives at least 10 dB (S+N)/N into 600 ohms adjustable via potentiometer (<5 uV to >10,000 uV)
• Selectivity: -6 dB at +/-9 KHz, -60 dB at +/-40 KHz
• Adj Channel Selectivity: 65 dB at 25 kHz
• Intermodulation: -65 dB type dB; typical at 25 kHz
• Spurious Rejection: 80 dB at 25 kHz
• Spurious Emission: Conducted: <-60 dBm
• Radiated: -60 dBm < 1 GHz
• Timebase Stability: +/-30 ppm, includes aging

• Test Switch: Pressing this activates the relays just as a received microphone click would.
• Reset Switch: Resets all energized relays.
• RS-232C Serial COM Port: Allows authorized changes of operating frequency via a Windows PC program (M2115RCUPC). Password Protected. Software Included.
• Status LED: Blinks at a rate of once per second to indicate normal operation.
• Window LED: Lights when the first valid click is detected. Remains on for the allowed window duration (3 to 5 seconds depending upon DIP switch settings)
• Relay LED's: Visual indication of the adjacent relay state.
• DIP Switches: Allows field configuration of relay timing and behavior.
• Sw 1, 2 & 3 - "Timeout Period". (Variable from 3 seconds to 1 hour) (Optionally can be programmed for 8 hour and 12 hour max timeout)
• Sw 4 - "Window Time" (3 sec or 5 sec)
• Sw 5 - Relay Deactivate Disable. Relays will only de-energize at timeout period expiration.
• Sw 6 - "Mutually Exclusive" relay operation. Only one relay is ever active at one time. When the 5 click relay energizes, the 3 click relay de-energizes. Same for the 7 click.
• Sw 7 - "5 Click-Off" function. If only one relay is installed, this setting allows the customer to turn on the lights with 3 clicks, and turn them off with 5 clicks.
• Sw 8 - "7 Click Off" function. Same as 5 Click off function except it turns all the energized relays off with 7 clicks.
• Relays: 1, 2, or 3, form A, SPDT, standard unit 3 form A (SPDT), plug in for FAA unit.
• Mechanical Life: 100,000 operations.
• Switch Circuit Protection: Fuse or circuit breaker as specified by the user.
