4.6Engineering Test Modes (AT In)

Format modes:

 

 

To enable the function

AT In=1 <CR><LF>

To disable the function

AT In=0 <CR><LF>

Modem responds with

OK <CR><LF>

Read status:

 

AT In?<CR><LF>

Modem responds with

m <CR><LF> where m=0, not active

 

 

m=1, active

Where

n = 2

Output Continuous Preamble (used for

 

 

checking transmitter and receiver). The

 

 

preamble is transmitted until stopped by the

 

 

ATI2=0 or AT I=10 commands, or ending the

 

 

command mode. Note: for a G-Max, this test

 

 

must not be run for >10 minutes as damage to

 

 

the transceiver may occur.

 

n = 3

Output a series of 49 byte long data packets

 

 

with a programmed period between each

 

 

packet set with register S162. The message

 

 

data sent is: “The quick brown fox jumps over

 

 

the lazy dog.<CR><LF>” Each line of data is

 

 

pre-ceded by “XX “ where XX is a line number

 

 

which increments from 00 - 99.

 

 

The data is transmitted until stopped by the

 

 

ATI3=0 or AT I=10 commands, or ending

 

 

command mode.

 

n = 4

Adds the Output Data quality and Signal level

 

 

data to the end of each received data packet.

 

 

This is ended by the ATI4=0 or AT I=10

 

 

command. The data format is:

 

 

R:XX, D:XXX<CR><LF>

 

 

where XX = 1 - 10 and XXX = 66 - 256 as

 

 

defined in paragraphs 5.10 and 5.12

 

 

Note: if data is received before the values have

 

 

been read then R:XX, D:XXX<CR><LF> will be

 

 

output.

 

n = 9

Gives information about the software version

 

 

(refer to paragraph 5.7).

 

n = 10

Turn off test modes
