I'm trying to connect this laser sensor to an RS-232 port: link
I should connect TxD to RxD (DB9 pin 2) and RxD to TxD (DB9 pin 3), but what pins should I connect the "0V" and "+Vs" lines to? As far as I understand, connecting these lines provides power to the laser. According to the laser specs:
voltage supply range +Vs: 12 ... 28 VDC
current consumption max. (no load) 80 mA
Can an RS-232 port handle this and if yes, which pins should I connect "0V" and "+Vs" to?
Thanks.
