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), the transmission mode as well as
transmission rates must be adjusted. At delivery status the following default parameters are set:
Baud rate:
9600 Baud (if not mentioned otherwise)
Data format: 7, Even, 1 (if not mentioned otherwise)
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
&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 set-
ting (1 = result codes suppressed)
DTC=60:
Data transmit control (connection check) active: 60 seconds
Keep Alive=0: TCP/IP-Line check
PORT=1234: Standard port number = 1234
This configuration allows for reading meters of type VDEW (IEC1107 / IEC62056-21). If you want
to change this parameters, a PC with terminal software (e.g. UniModSet, Windows HyperTerminal
etc.) is needed. Moreover, experiences with the Hayes AT modem command set are highly 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 (#9177)
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 carefully 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 Ethernet can now be programmed with the software UniModSet.
5. After programming switch off the UniMod and insert the interface module carefully again.
