Extended command set mode
In this mode the PHC10-3 PLUS uses the Renishaw extended command set. It is completely different from and incompatible with the basic
command set. The RS232 protocol is fixed with no user selectable options other than baud rate. The extended command set offers the
following advantages over the basic command set:
Software control of the hand control unit (HCU2) functions such as jog and sweep
Software control of selected PICS (product interconnection system) functions such as probe damping, Probe Power OFF and LED OFF
Software control of selected probe functions (TP200 probe reset) common communications protocol for products using the extended
command set
Please contact Renishaw for further details of the extended command set.
NOTE:
The functions of switches 4, 5 and 6 will have no effect on the system when switch 9 is UP.
In extended command set mode, the data transmission and protocol formats are fixed in line with modem RS232 conventions. There are no
user selectable options.
Data transmission format is as follows:
1 start bit
7 data bits
1 even parity bit
1 stop bit
Protocol:
PHC10-3 PLUS RTS is normally asserted. It is de-asserted when the PHC10-3 PLUS is unable to receive further transmissions.
The PHC10-3 PLUS CTS must be asserted (by the CMM computer, or by linking DTR to CTS) to allow the PHC10-3 to transmit.
XON/XOFF:
The extended command set supports the use of XON/XOFF flow control by the CMM computer.
If the PHC10-3 PLUS receives an XOFF character, PHC10-3 PLUS transmissions will cease and be buffered until an XON character is
received by the PHC10-3 PLUS or the output buffer overflows.
It is possible to continue transmissions to the PHC10-3 PLUS while it is in the XOFF state, although this is not recommended as it may
cause overflow of the output buffer, resulting in lost responses.
