Strange...

Have tried half or full duplex no response. I use usb-COM port adapter. from DB9 i use 2,3 for rxtx and 5 for GND. LM started responding when i disconnect GND from RS port of LM just rx tx pins.
LM starts sending response back but not correct data for modbus just echos same query back. Modbus master fires illegal response exception then.

TX [01][03][00][00][00][0A][C5][CD]
RX [01][03][00][00][00][0A][C5][CD]
