8.1 Modem Configuration 

You must configure the modem before it is connected to MR004FA or MR004DL. 
Please use a terminal software of  your choice, e.g. the Windows HyperTerminal and 
connect the PC to the modem. Choose 9600 baud, 8 data bits, no parity and one 
stopbit. Then input the following commands, each activated by the “Enter” key: 
 

Command 

Function 

AT 

for baudrate detection 

AT&F 

load factory settings 

AT&D3 

resets modem after DTR signal off 

ATS0=1 

modem answers a call after one ring 

AT\Q0 or AT&K0 

deactivate hardware and software handshake 

AT\J0 

no adaption of the serial baudrate to line speed 

AT&W0 

stores the settings into profile 0 

AT&W1 

stores the settings into profile 1 

 
These commands are examples, which will work with several, but not all modems on 
the market. Please study the manual of your individual modem to find out whether you 
need to use modified commands. 
 
After configuration please connect the modem to the MR004FA/DL using the cable 
delivered with the modem and plug it into the DSUB labelled with “MODEM”.
