Figure 5: AirSmart RS485 Communication Wiring Schematic
is the hardware Interface for the RS485 Connections on the IO Module shown in the wiring
diagram in Figure 5. Make sure that the machines at the end of the sequencing network have the
RS485
terminating resistor DIP switch in the ‘ON’ position. The location of the terminating resistor
selection for X02 is highlighted below in Figure 6
Figure 6: IO Module DIP Switch Settings at RS485-1 Port
shows the RJ-45 adapter (PN: 24CA7402) used on existing AirSmart G2 control
systems which use an RJ45 connector for the sequencing network. This part is included in the
AirSmart G2 sequencing kit, and should be utilized if connecting to an existing network of
AirSmart G2-controlled machines. Using the cable supplied in the sequencing kit, the
terminations on the connector are as follows: GND or C on terminal 8, RS485 + on terminal 2,
and RS485 - on terminal 1. With the RS-45 pins facing upwards as shown below, the topmost
terminal is referred to as terminal 1.
