1.2.1 Class 1 modules
The LRX is eye-safe in every measurement mode.
The system which uses Class 1 LRX module shall have labelling according IEC 60825-
1:2014 as follows:
Text borders and symbols are recommended to be black on a yellow background, but for
Class 1 this color combination need not be used.
The labels shall be durable, permanently affixed, legible, and clearly visible during
operation, maintenance or service, according to their purpose.
If the size or design of the product makes labelling impractical, the label shall be included
with the user information or on the package.
Direct printing or engraving of equivalent labels on the laser product or panels is
acceptable.

pin # IN/OUT Description
1 IN RS-422 RX+ (or UART TXD) *1
2 IN RS-422 RX- (or RS-232 RX or UART RXD) *1
3 GND RS-422 GND
4 OUT RS-422 TX+ *1
5 OUT RS-422 TX- (or RS-232 TX) *1
6 GND Case/Supply ground *2
7 & 8 IN Supply voltage input (6.5 - 30V). Reverse voltage protected. See Table 5
for power consumption.
9 GND Case/Supply ground *2
10 IN Shutdown when pulled down <0.5V, Power On when > 1.1V(internal 100
kΩ pull up)
*1 The default interface is RS-422. Serial interface option must be defined during ordering.
*2 Isolation of the case from the electrical ground is possible. Isolation option must be defined in the order!

3 Serial communication protocol
This chapter describes the main commａnd frames of laser range finder. Notice that all
commands described in earlier ICD document versions are still supported.
Default baud rate is 115200 bps (no parity, 8 data bits, 1 stop bit). Default electrical
interface is RS-422. RS-232 and UART are options. Serial transfer speed can be changed
by the user.
After about 50 ms from the power on the device sends a string “LRX x.x.x" where “x.x.x"
is the firmware version (e.g. 1.5.3). After the string the device is ready to take commands.
