Hi pat

Read at first:
ftp://ftp.moeller.net/DOCUMENTATION/AWB_MANUALS/MN04902001Z_EN.pdf 2.8 Connecting the serial interface
and  IL05013021Z (AWA2528-2345) by using EASY800-MO-CAB  for Pin assignment (modem is cross over!!)

 Adjust adapters for standard serial rs485 connection, connect EN on high level
J1-3 must be in Factory setting

see FIGURE 2.6 CONNECTIONS FOR FULL AND HALF DUPLEX OPERATION
and FIGURE 2.8 NETWORK BIASING RESISTORS (test without biasing resistor in half-duplex mode)
