Synchronization using Clear To Send (CTS) and Request To Send (RTS) signals
In many applications, the synchronization interface is based on an RS-232 serial port. Only the Clear to Send (CTS) and Request to Send (RTS) signals on the serial interface are used.
RS-232 uses two signal levels to distinguish between a logical "1" (also called
"High"), and a logical "0" (also called "Low"). The EK80 system triggers on logical high.
| A | Local connection |
| B | Connection on remote device |
| C | Female 9-pin D-Subminiature connector |
| D | Male 9-pin D-Subminiature connector |
Note
RS-422 communication ports can not be used for synchronization purposes. The port you wish to use must be set to RS-232.
