4.3.3 Communication

There are three communication protocol sub-menus available on the

Communication

screen:

Ethernet,

RS485 0,

and

RS485 1

.

Note, certain machine configurations will show an additional RS485 port labeled

RS485 2

, which will have

identical settings to the

RS485 1

port.

Ethernet:

Under

Ethernet

settings, the following parameters can be set:

Ethernet Configuration Mode

between

Static

and

DHCP

from drop down menu,

IP Address

with number pad entry,

Subnet Mask

with number

pad entry, and

Gateway Address

with number pad entry. Figure 92 below shows the

Ethernet

tab settings.

Note that if the controller is set to DHCP it will automatically attempt to retrieve IP network settings from a
local DHCP server. In this case you will not be able to set the other values and the IP addresses that are
acquired will be shown in the respective fields.

Figure 92: Ethernet

RS485 0:

Communication

Mode

can be selected between

Disabled, Sequence

– AirSmart, Sequence – Delcos,

Sequence

– ES+, Modbus Master,

and

Modbus Slave

from drop down menu. Figure 93

below shows the

mode selection drop-down menu options.

Table 33: Communication Modes

Communication Modes

Mode

Function Description

Disabled

The communication mode for this port is disabled and not functional

Sequence

– AirSmart

AirSmart Protocol can sequence up to 8 variable speed or fixed speed compressors or
a mix of the two. This protocol is designed to handle sequencing and load sharing for
direct and optimal control

Sequence

– Delcos

Delcos Protocol can sequence up to 4 compressors, one compressor must be
configured as the master with up to 3 slaves connected. All slave machines run off the
master machine’s delivery pressure sensor.
