Short Data Messages (SDM)

Short data messages may be set up, sent and

received using the radio keypad and controls.

Outgoing data messages from the keypad are

limited to numeric data only in any combination of

up to 20 characters (which include address

information and data selection characters

Receiving Short Data Messages

On receiving an SDM, tone G sounds and the

display shows:

The data message icon

are in the data message stack, i.e. displayable,

unless the message display has been turned off

(refer to Displaying Incoming Data).

Displaying Incoming Data

The short data message display can be switched

ON and OFF using the keypad controls as follows:

♦

Enter

23000

short data display.

♦

Enter

23001

short data display.

The SDM display defaults to ON, however the option

setting is retained when the radio is switched off.

Note:

This feature is important if the radio is being used

with external data terminal equipment (DTE), to

prevent loss of data messages.

With the SDM display set to ON, on reception of a

valid SDM, either it can be displayed by the radio

and/or passed to external DTE. In either case, the

SDM is received and accepted (acknowledged) by

the radio. Only if the SDM is of an un-displayable

format AND the external DTE is disconnected, is the

SDM rejected by the radio.

With the SDM display set to OFF, on reception of a

valid SDM, it will not be added to the data message

stack for display, but passed to the external DTE,

which if accepted will be acknowledged by the radio.

However, if the DTE is not present e.g.

disconnected, the SDM is rejected by the radio. In

this case the SDM will not be accepted

(acknowledged) by the radio and will not be lost.
