QK-A015-TX Manual
Active VHF/AIS Antenna Splitter

Features
· 12V-24V powered, low power consumption · Allows use of a single VHF antenna installation shared between AIS transponder, VHF radio
telephone and FM/AM radio · VHF failsafe function - VHF radio has full priority and will remain functional, even in the unlikely
case that the Splitter would fail or lose power · Built-in preamplifier provides AIS signal gain (12dB), maximising AIS reception range. · Automatic routing of AIS and VHF transmission · Uses standard SO239 connector for VHF, AIS and antenna connections · LED power and status indicator · Compact & easy to install. No configuration required

QK-A015-TX Manual
1. Introduction
The QK-A015-TX splitter allows one VHF antenna to be shared between,
· VHF radio · AIS transponder and · AM/FM radio
The A015-TX allows the one VHF antenna to provide the following functions: · Reception of VHF radio, AIS messages and AM/FM radio. · Transmission from VHF radio and AIS transponder · Straight forward connection to all relevant devices, with no configuration required. · VHF radio always has priority and can always transmit in the case that the power to the splitter fails · Low power consumption.
The A015-TX is an active splitter. This is an important feature, as unlike many splitters that cause signal loss, the active splitter actually provides a signal gain. The A015-RX's built-in pre-amplifier amplifies the AIS, VHF, AM/FM signals, thereby increasing the AIS transponder's reception range.
Please note: The A015-TX is compatible with AIS transponders/transceivers. (Though the A015-TX could be also be connected to AIS receivers, the A015-RX is only compatible with `receive only' applications.)
2. Connections

The A015-TX has five connections:
· Power cable: 12V-24V DC power · VHF Antenna: SO239 connector for VHF antenna · VHF radio: SO239 connector for VHF radio · AIS: BNC SO239 connector for the AIS transponder · FM/AM: BNC connector for the output of the FM/AM radio signal

3. Installation
The A015-TX is a plug and play device, with no configuration required.
IMPORTANT: Connect the VHF antenna BEFORE connecting any other devices! Do not connect powered devices to a splitter until the other steps below have been followed in the correct order. Connecting powered devices to a splitter before the other steps will damage your devices. 1. Remove power source from the A015-TX 2. Remove power source from all devices to be connected 3. Connect the VHF antenna to the Splitter before adding power or any devices. 4. Connect all other devices (unpowered) to the A015-TX (ie. VHF radio, AIS transponder and
FM/AM radio) 5. Power the A015-TX 6. Power all connected devices (ONLY do this AFTER following the above steps in the correct
order) 7. Checking status LEDs light up when expected
4. Status LEDs
The A015-TX has four LEDs that indicate power and working status.
- VHF TX: Transmitting VHF radio - AIS TX: Transmitting AIS - ERR: Indicates an error (check your Antenna connection) - PWR: indicates power

The ERR LED will illuminate if the antenna has short or open circuit. If this happens, de-power the A015-TX immediately. Disconnect all connected devices and check if the VHF antenna is well connected. Then re-follow the steps above. Contact a local installer for a professional help if needed.
For safety purposes, the A015-TX has an automatic VHF fail-safe. This means that the VHF radio has full priority and will remain functional, even in the unlikely case that the Splitter would fail or lose power.
