Communication Drivers
This group of settings is used to set the configurations inherent in the Serial Port Settings propertiygroup for the selected station.
The serial is managed by the modem's driver when the station's TAPI settings are used for managing communications via modem. The settings with which the serial is opened are therefore those defined in the modem's driver's advanced properties and may differ to those set for the Movicon driver station ("Serial Port Settings").
Port
Default value = 1. This is used to set the number of the serial port to be used for communicating. I.e. value = 1 for COM1
|
Note: you need to make sure that no conflicts occur in Windows when using the ports. For instance, when installing the Com4 port, you will need to make sure that the assigned address and the IRQ are compactible with the PC's configuration. In order to do this we advice you use addressable serial cards. |
Baud rate
Default value = 9600. This is used to set the velocity of the serial communication (Baud Rate). The value of the communication's velocity must correspond to that of the device to be communicated with.
Byte Size
Default value = 8. This is used to set the amount of bytes required by the communication protocol in use.
Parity
Default value = Even. This is used to set the parity type required by the communication protocol in use.
Stop Bits
Default value = 1 stop bit.This is used to set the number of Stop Bits required by the communication protocol in use.
Flow Control
Default value = None.This is used to set the data Flow Control type for the type of communication in use. This property allows the flow of communication data from the connected device's serial port to be adapted to low level protocol requirements. The default 'None' value means no flow control type, but you might need to select one when signalling errors with code "1" for example.
The options are:
None: No Flow Control. Control not required by protocol.
Hardware: Flow Control is managed by electric serial line electric signals (i.e. RTS, CTS, ecc.).
Xon/Xoff: Data Flow Control is Xon/Xoff type.
NONE (Signal disabled): Flow Control set to NONE and serial is set for disabling the DTR and RTS signal management.
RTS Toggle: Sets the serial for managing RTS signal control in Toggle mode, meaning the serial keeps signal high when there are characters to be sent.
