8. Power Supply
The AMP2440P comes with a power supply that have standard 2.1 mm barrel plugs (which are configured
as positive (+) tip and negative ( - ) outer conductor). Although normally supplied with a power supply, any
regulated 12 Volt DC 1 amp supply can be used. The power supply provided with the kit can be used with
110 or 240 VAC power.
9. Operation
The unit operates automatically and there are no user adjustments.
These modems “ping-pong” back and forth between transmit and receive so quickly during normal operation
that both the TX and RX LEDs will appear to be lit simultaneously. In fact, they are turning on and off so
quickly that they appear to be on all the time. You can tell how quickly one of these LEDs are turning on and
off by their brightness. Their glow will be slightly dimmer when they are off.
