PICS connection
PICS interface configuration
If the PHC10-3 is to be used in a PICS linked system, the PPOFF configuration is selected using switch 7.
| Switch | Description | Position | |
| 7 | PPOFF | UP | PPOFF and PDAMP active during head index |
| 7 | PPOFF | DOWN | PDAMP only active during head index |
PICS output
Renishaw's PICS (product inter-connection system) allows a standard method of connection for real-time signals used by current Renishaw products and gives access to probing system control features through the DIN 'raw probe' connection.The following descriptions are specific to PHC10-3 PICS connections when an internal interface is not present. Please refer to the PICS installation guide (Renishaw part number H-1000-5000) for further information when interfaces are fitted.
| Pin | Signal | Function | - |
| 1 | STOP | This signal is active when low and is responded to, and can be asserted by the PHC10-3. | Read from PHC10-3 to indicate an error in the PH10 system. Pull down to 0 V to indicate a STOP condition external to the PH10 system. |
| 2 | PPOFF | PPOFF is an active low inhibit signal which can be set by the CMM computer or the PHC10-3. PPOFF is overridden by the use of the STOP signal. | - |
| 3 | 0 V | This the common reference and return path for all signals. | - |
| 4 | LED anode | This is a constant current input, normally from the interface to illuminate the head LED. | - |
| 5 | Probe Signal | This pin and pin 9 transmit the probe output signals from the PHC10-3 when a multiwire cable is not in use. As these signals have not been interfaced, it is important that the PICS cable between the PHC10-3 and the interface is less than 0.5 m (1.6 ft) otherwise interference from other PICS signals can occur. | - |
| 6 | SPARE | - | - |
| 7 | PDAMP | PDAMP is an active low signal which can be set by the CMM computer, the PHC10-3 or by the optional HCU1. PDAMP can influence an interface by reducing electronically the sensitivity of a strain gauge based probe. It can inhibit a Renishaw interface, when standard touch trigger probes are in use, until the probe has been continuously triggered for at least 5 ms. The signal can be asserted by the CMM computer to reduce the sensitivity of the probe. This will reduce unwanted triggers during CMM acceleration, or vibration during position moves, whilst maintaining crash protection. | Pull down to 0 V to partially inhibit the probe during rapid moves. |
| 8 | LEDOFF | This signal is not asserted by the PHC10-3, but it responds to LED OFF by switching the head LED off. | - |
| 9 | Probe Return | See Pin 5 | - |
