Remote Functions
en
KEYLOCK Function (SET Button Block)
If during sensor power-up the SYNC wire is connected to +V DC for at least one second, the keylock function will be activated and buttons will no longer be
active. After the first second, the SYNC input is available for the normal operating modes.
To deactivate the keylock, the sensor has to be turned off and re-powered with the SYNC wire not connected or ground connected (GND).

RS485 Serial Connection (Only For E75-CLRMKRS-M12)
Complete sensor remote control is possible using the RS485 line. All functions, such as channel, tolerance and operating mode selection,
can be accessed via the serial connection. The serial communication parameters are as follows: 9600 baud, no equity, 8 data bits, 1 stop bit.
All commands have to be sent via terminal in an ASCII format as follows:
Received Channel Status
At any moment, the receipt of the 'r <CR> <LF>' command indicates the sensor configuration.
Remote Setting Mode
To access the remote setting mode, the SYNC input must remain passive for at least 300 ms. The commands available are:
@ <CR> <LF> Beginning of the remote setting (together with passive SYNC)
cx <CR> <LF> Channel selection, with x {1,2,3}
tx <CR> <LF> Tolerance selection, with x {0,1,2,3,4,5,6,7,8,9}
mx <CR> <LF> Operating mode selection, with x {1,2}
e <CR> <LF> Configuration sequence activation
q <CR> <LF> Exit from remote setting mode without saving configuration
If the SYNC input is activated before the 'e' (execute) command is given, the sensor exits the remote setting mode without saving the configuration,
similar to the 'q' (quit) command.
If the SYNC input is active at the receipt of the '@ <CR> <LF>' command, the sensor responds with: '?? <CR> <LF>.'
At the receipt of the 'q <CR> <LF>' or 'e <CR> <LF>' commands, the sensor transmits 'ok <CR> <LF>.'
The 'lo <CR> <LF>' message is transmitted if the signal is too low and 'hi <CR> <LF>' if the signal is too high.
Delay Configuration
To access the delay configuration, the SYNC input has to remain passive for at least 300 ms. The commands available are:
@ <CR> <LF> Beginning of the delay configuration (together with passive SYNC)
dx <CR> <LF> Delay selection, with x {0,1,2,3,4,5}
e <CR> <LF> Memorization of the new delay
q <CR> <LF> Exit from the delay configuration without saving
If the SYNC input is active at the receipt of the '@ <CR> <LF>' command, the sensor responds with: '?? <CR> <LF>.'
At the receipt of the 'q <CR> <LF>' or 'e <CR> <LF>' commands, the sensor transmits: 'ok <CR> <LF>.'
￫ During the command transmission, single strings have to follow each other with a delay of at least 1 ms.

The status of the SYNC input can determine the beginning and end of color
identification. The sensor operates normally with all outputs functional with the
SYNC input disconnected (or connected to 0 V). When you connect +24 V to the
SYNC input, the sensor outputs are disabled and color sensing stops (after the
time delay shown in the drawing at left). This may be useful with a multi-colored
target where the color to detect is in a specific position, while other zones should
be ignored.
