The green part of the drawing shows the proceeding for Compax3 release versions
< R5-0!
The proceeding for Compax3 release versions < R5-0 is described in an applicati-
on example (.../modem/C3_Appl_A1016_language.pdf on the Compax3 CD).
Connection Compax3 ServoManager <=> Compax3
The Compax3 ServoManager (1) establishes a RS232 connection with modem 1
(PC internal or external).
Modem 1 dials modem 2 via a telephone connection (3).
Modem 2 communicates with Compax3 (6) via RS232.
Configuration
Modem 1 is configured via the Compax3 ServoManager (1)
Modem 2 can be configured via Compax3 (on place), triggered by putting
SSK31
(see page 388) on X10. For this, the device must be configured before. This can
be made lo
cally before the system / machine is delivered with the aid of the Com-
pax3 ServoManager (8).
The transmission was tested with a TD33 modem made by "
Westermo
http://www.westermo.com". The configuration with this standa
rd modem is especi-
ally simple.
Other modem types are also possible.
5.3.2. Configuration of local modem 1
Menu "Options: Communication settings RS232/RS485..." must be opened
Select "Connection via Modem"
Under "name" you can enter a name for the connection
Enter the target telephone number.
Note: If an ISDN telephone system is operated within a company network, an ad-
ditional "0" may be required in order to get out of the local system into the coma-
ny network before reaching the outside line with an additional "0".
The timeout periods are set to reasonable standard values according to our expe-
rience.
Select the modem type: "Westermo TD-33" or "user-defined modem"
For "Westermo TD-33", no further settings are required.
For "user-defined modem", additional settings are only required, if the modem
does not support standard AT commands.
Then you can enter special AT commands.
Note: When operating the local modem on a telephone system, it may be ne-
cessary to make a blind dialling. Here, the modem does not wait for the dialling
tone. For the Westermo TD33, the additional command sequence is ATX3.
Select the COM interface where the modem is connected.
Close the window and establish the connection with button (open/close COM
port).
The connection is interrupted when the COM port is closed.
