AEP MP2x8i NMEA Buffer User manual

The MP2x8i NMEA Buffer isolates and buffers NMEA 0183 data or other RS422 signals.
It is able to distribute the NMEA signal from two Talkers up to eight Listeners. As the (power)
input and output ports are isolated the device ensures the protection of the Talkers and
Listeners. The MP2x8i features two operating modes; auto-switching mode and dual mode.
In auto-switching mode you are able to connect two independent Talkers and distribute the
signal to eight Listeners. In dual mode the buffer can be used as two independent buffers with
one input and four outputs.

Operation modes
1. Auto-switching mode: If input signal #1 is lost for 30 seconds,
it will automatically switch to input #2.
2. Dual (independent) mode: Two independent buffers with 1-in and 4-out signals.
Terminal description
DIP-switch:
SW1 On: Auto-switching mode
SW1 Off: Dual (independent) mode
SW2: Not available
LED indicators:
Power LED: Will blink continuously when
power input is connected correct
Auto-switching mode: Input 1 LED and input 2
LED will blink simultaneously at data rate
Dual mode: Input 1 LED and input 2 LED will
blink separately at data rate
Caution: Do not install or disassemble
your equipment when the power
supply is connected to the device.
Failure to do so could result in personal
injury or damage to the equipment.
