Serial Communications

The serial ports (S1-1 & S1-2, S2-1 & S2-2, S3-1 & S3-2) support the following

signal modes depending upon use:

 RS485fd: A four-wire full duplex connection that features separate busses for

transmit and receive. This selection should also be used when the controller is

acting as a Modbus master using the optional four-wire definition described in

Section 3.3.3 of the Modbus-over-serial standard.

 RS485fdmux: A four-wire full-duplex connection with tri-state outputs on the

transmit connections. This should be used when the controller is acting as a

Modbus slave on a four-wire bus.

 RS485hdmux: A two-wire half duplex connection appropriate for or master slave

or slave use. This is shown in the Modbus-over-serial standard.

T9300 I/O Base Unit (3 way)

The AADvance controller has T9300 I/O base units for the I/O modules. An I/O base

unit supports up to three I/O modules (of any type), and their associated termination

assemblies.

It contains a passive backplane that provides the electrical connections between the

I/O modules and the T9100 processor base unit; i.e. the command and response buses

and the system power.
