After configuring the communication channel, you need to enter the transmission parameters.
These are split into four windows:
This window looks like this:
You can use it to select the transmission speed of the character mode protocol used by the module:
-
The default speed is 9600 bits/s.
-
Other available speeds are 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, and 57600 bits/s,
-
The speeds 300 and 600 bits/s are only available using the PCMCIA TSX SCP 111 card.
-
The speeds 38400 and 57600 bits/s are only available using the PCMCIA TSX SCP 1114 card.
-
You are advised to adjust the transmission speed according to the remote device in use.
This window looks like this:
The Data field specifies the size of the data exchanged over the line. The possible values are 7 and 8 bits. You are advised to adjust the number of data bits according to the remote device in use.
NOTE: The default value is 8 bits.
This window looks like this:
The Stop field allows you to fill in the number of stop bits used for communication in character mode. The possible values are 1 or 2 stop bits. You are advised to adjust the number of stop bits according to the remote device in use.
NOTE: The default value is 1 stop bit.
This window looks like this:
This field is used to set whether a parity bit is added or not, as well as its type. The possible values are Even, Odd or without (Odd by default).
You are advised to adjust the parity according to the remote device in use.
This window looks like this:
Before a character string is transmitted, the module activates the RTS (Request To Send) signal and waits for the CTS (Clear To Send) signal to be activated.
-
This allows you to enter the maximum waiting time between the two signals. When this value is timed-out, the request is not transmitted on the bus.
-
The value is expressed in hundreds of milliseconds.
-
The default value is 0 ms.
-
The value is between 0 and 10 s.
-
The value 0 specifies an absence of delay management between the two signals.
-
Data carrier management (DCD signal - Data Carrier Detected) is used only for communication with a modem with a controlled data carrier.
-
If the option is selected, the characters are only valid on reception if the DCD signal is detected.
-
If the option is not selected, all characters received are taken into account.
