The HomeBase is a device that is connected to the serial port of the PC. It takes care of

all the RF communication from and to the WaiterMate handheld terminal.

The power supply used with the HomeBase is the standard power supply delivered with

the HomeBase. When the HomeBase is delivered with a RJ-connector inserted into the

RS-485 connector this is to prevent a wrong insertion of the serial  dongle-HomeBase
cable.

To hook up your HomeBase to your serial  dongle you only need to plug in the cable with

the RJ connector in the correct connector (RS-232) and plug the cable into the serial

dongle.

Once you have inserted the cable into the RS-232 connector, the HomeBase will start-up.
When the HomeBase starts up, the LED near the power supply will follow a fixed

sequence; this sequence is defined per protocol.

The sequence followed is as follows:

Orange LED (Boot of HomeBase)

Blinking red LED (This indicates the protocol used)

1 time

= protocol A

2 times 

= protocol B

3 times 

= protocol D

A short pause (LED is out)
Blinking red LED (a repeat of the previous sequence)

Green LED (the HomeBase has finished starting up)
