on the e-mail address entered in the To: field. The alarm message

appears in the Subject field of the e-mail. The e-mail can be empty,

because the content is ignored.

E-mail handling procedure in DECT Messenger

After you send an e-mail message to DECT Messenger, the message

enters at the SMTP port of the IIS SMTP Server. The IIS SMTP Server

drops the message in a directory on the hard disk. The eSMTP_Server

module checks this directory at regular intervals for newly arrived e-mail

messages. If there is an e-mail, eSMTP takes the message from the

directory and analyses it. The e-mail address entered in the To: field

of the e-mail is translated into a device (or group of devices) to which

the e-mail must be sent. The Subject: field of the e-mail informs the

devices of the nature of the message. After the message is processed, the

eSMTP_Server sends a confirmation to the address entered in the From:

or X-sender field of the message to inform the user whether the message

is accepted or not.

eAPI

The eAPI module is simply a TCP/IP socket input on the eKERNEL. You

can write your own program to send data to the eKERNEL and generate

an alarm with the eAPI. You can write your program in any programming

language, because the eAPI interface is a socket interface. For more

information on the eAPI interface, see Module eAPI in

DECT Messenger

Installation and Commissioning (NN43120-301). Also included in the

chapters are examples of programming code you can use to write your

own eAPI program in Visual Basic. A sample program is also available

that ships with the software, called eAPI. The eAPI program is an .exe file,

and is supplied as source code for Visual Basic. If you are familiar with

programming in Visual Basic, you can use the eAPI to create your own

interface DECT Messenger.

The eAPI module is often used to develop an application to convert an

unsupported protocol to the DECT Messenger protocol. This requires a

detailed specification of the unsupported protocol, and a test system that

uses the unsupported protocol.

eWEB

The eWeb module can send messages (entered using a web interface) to:

• LRMS (E2)-compatible DECT handsets (C4040, C4050, 4060,

Industrial handset, and so on)

• e-mail using eSMTP (Client)

• Any other output module in DECT Messenger, for example:
