6. 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 (e.g. meter) and the transmission mode and
transmission rates must be adjusted. On delivery the following default parameters are active:
Baud rate:
9600 Baud (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.
\N3
Error correction V.42 or MNP 4 possible
&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.
&K0:
No local flow control
E0:
This setting determines whether or not the modem echoes characters received
from PC during command state. (0 = no echo)
Q1:
This parameter setting determines whether or not the modem transmits any
result code to the PC. Information text transmitted in response is not affected by
this setting. (1 = result codes suppressed)
This configuration allows for reading meters of type VDEW (IEC1107 / IEC62056-21). If you want
to change this parameters, you need a PC with terminal software (e.g. UniModSet, Windows
HyperTerminal etc.). Moreover experiences with the Hayes AT modem command set are very rec-
ommended. To establish connection between PC and modem you have to use:
A) the parametering adapter with USB port (#12823)
B) the parametering adapter with RS232 port (no more available)
C) the converter (converter box or ConvBox) to adapt the interfaces (#12685)
Description of the connection options:
A)
The parametering adapter with USB port (Micro-
USB Type A or B), which can be plugged instead of
an interface module. This adapter can be ordered
as accessory (Order No.: #12823).
1. First connect the adapter with the USB port at the PC and wait for confirmation. The new COM-
Port can be find in the device manager (control panel):
USB Seri
al Port (COM…)
.
2. Then disconnect the modem from the supply (
important!
) and remove the interface module.
3. Now you can plug the parametering adapter into the 7-
pole jack (the LED’s must point downwards).
4. The UniMod 01/I can now be programmed with the software UniModSet.
5. After programming switch off the UniMod and insert the interface module carefully again.
