Chapter 3. Communications Operations of BHT-5000
■
RS/CS Control
Depending upon whether the RS/CS control is enabled or disabled in System
Mode, the BHT-5000 operation will differ as follows:
RS/CS Control
BHT-5000 Operation
Enabled (ON)
If the CS signal is ON when the BHT-5000 is ready to send, the
BHT-5000 will send data. If it is OFF, the BHT-5000 will wait for
the CS signal to go ON until the timeout occurs.
When the BHT-5000 becomes ready to receive data, it will turn
the RS signal ON.
Disabled (OFF)
The BHT-5000 does not check the CS signal when starting data
transmission.
The RS signal is always ON.
The timeout length is programmable in user programs written in BHT-BASIC
3.0. If not designated in programming, it is three seconds.
For the RS/CS control in user programs written in BHT-BASIC 3.0, refer to the "BHT-
BASIC 3.0 Programmer's Manual."
