Controlling COM1...4 index card
This dialogue screen allows you to set the parameters of the serial interfaces on
the video matrix. Any reference made here to COM1 to COM4 relate to the
SIMATRIX and must not be confused with the COM1 to COM4 connection ports on
the PC! The serial interface on the PC, which is used to connect the PC and the
SIMATRIX, can be set in the Active interfaces dialogue screen.
15.2.1 COM2, COM3, COM4 interface settings
The interface settings must be configured for each interface used by selecting the
desired values.
As standard, COM1 should be set to a baud rate of 2400 baud, as the devices
connected to this port (keyboards, CDC) are set to 2400 baud as standard.
COM2 to COM4 should be set as standard to a baud rate of 19k2 and a data
format of 8,E,2.
Caution
If the data format or baud rate setting for an interface are changed, the new
values will only take effect after a power-off reset, i.e. by interrupting the mains
supply and restarting the SIMATRIX.
Caution
One interface must always be set to I9K2 and 8/E2, as parameterisation is not
possible otherwise.
