6.7 Serial Data Channel (Labelled Serial Sensor RS232)
The SSP provides a 9 pin D connector for the RS232 function of the serial data channel of the DT800.
This connector is configured the same as a COM port of a PC viz
•
pin 2 Receive
•
pin 3 Transmit
•
pin 7 RTS
•
pin 8 CTS
and so RS232 devices that can be connected to a PC can be connected to the SSP using the same
cable. The SSP does not provide any serial sensor simulation.
However the serial data channel could be demonstrated by connecting an RS232 serial dot matrix or
ticket printer to the SSP, or a PC running a terminal program such as DeTransfer or HyperTerminal,
and running the following program. (Prog10.dl8)
Fig. 21.
The program will print the message “Datataker DT800 Serial Sensor Port” every 10 seconds.
Similarly a dataTaker 500 range data logger could be connected to the SSP (make sure that the
DT500 series logger is reset and in default data format), and read the voltage on channel 1 of the
logger by the program. (Prog11.dl8)
Fig. 22.
This program requests the voltage on channel one of the connected DT500 and then waits for the
value to be returned.
