Page 32: Send Outputting One Single Message
_______________________________________________________________________ UIDE The POLL mode is used when several PTU200 series transmitters are connected to one RS232C serial interface. It is also used when several intelligent transmitters are connected to a half duplex RS 485/422 serial interface. In the POLL mode, the transmitter must have a specific address so that the host system is able to direct the outputting commands to the particular transmitter. -
Page 33: Open Setting A Transmitter From Poll Mode To Stop Mode
The CLOSE command is a global command and requires no address. The PTU200 series transmitters must always be closed after the POLL mode selection. The RESET command and powering-up will close the PTU200 series transmitters automatically. -
Page 34: Send Mode
_______________________________________________________________________ UIDE SEND mode In the SEND mode, the transmitter will automatically output one message at power-up or when triggering the transmitter on using pin 4 of the transmitter. The trigger signal must be a TTL level signal. TTL HIGH (5 VDC) turns the transmitter ON and TTL LOW (0 VDC) turns the transmitter OFF. -
