7 Programming the Modem
Before installing the modem it has to be programmed in order to meet the
demands. The baud rate and data format for connecting the target device
and the transmission mode and transmission rates must be adjusted. On
delivery the following default parameters are active:
Data rate 9600 Bit/sec (if not differently mentioned)
Data format 7, Even, 1 (if not differently mentioned)
S0=1
This parameter setting determines the number of rings (here 1) before
automatic answering.
&D0 This parameter determines how the modem responds when circuit 108/2
(DTR) is changed from ON to OFF during data mode. With setting 0 the
modem ignores DTR.
E0 This setting determines whether or not the modem echoes characters
received from PC during command state. (0 = no echo)
Q0 V0 Information response: numeric code
+IPR=19200 Internal baud rate:
don’t change this value!
+CBST=7,0,1 The modem selects the bearer service with data rate 9600 Baud,
asynchronous, non-transparent mode to be used when data calls are
originated.
This configuration allows for reading standard meters according to VDEW2
(IEC 1107 / IEC62056-21). If you want to change this parameters, you need
a PC with terminal software UniModSet/MetcomTSet. Moreover
experiences with the Hayes AT modem command set are very
recommended. To establish connection between PC and modem you have
to use the RS232-Service interface (A) or a parametering adapter (B),
Alternatively you can use a converter („converter box“) in order to adapt the
interfaces.
A) Service interface: Standard
RS232 cable with 9 pole plug
(Standard RS232, Order No.:
#4301).
