Configuring the RMC75S Serial Communications

The RMC75S port 1 supports most standard serial port options, several protocols, and several line drivers. These settings can be changed using RMCTools and saved to Flash memory.

The Monitor port (port 0) settings are fixed. See the Monitor Port topic for details.

Changing Serial Settings

To change the serial communication settings:

In the Project pane, expand the Modules folder, double-click the module with serial communications, and then click Serial.
Make the desired changes. For a description of the options, see the Configuration Options section in this topic.
Click OK.

Configuration Options

The following options are available under the Serial page in the serial module's Properties dialog:

Serial Port

Select port 1.

Note:
TheRS232 Monitor (port 0) port is used by RMCTools. It can be used for other serial communication as well, but its settings cannot be changed.

Protocol Settings

Select the protocol supported by your master device and the address of the RMC75S. The address must match the address that master device expects.

Serial Port Settings

The following settings define how data is sent over the wire:

Line Driver: Select the line driver you wish to use. For further details on the line drivers, see Line Drivers: RS-232/485.
Baud Rate: Select the baud rate from 9,600 to 115,200. This must match the other device(s) on the network.

NOTE:
Some of these options may be disabled depending on which protocol was selected. For example, many protocols require eight data bits, and as such seven data bits is not available when these protocols are selected.

Advanced...

These are advanced settings for the line drivers:

Data Length: Select seven (7) or eight (8) data bits. Most protocols require eight data bits. This must match the other device(s) on the network.
Parity: Select which type of parity error checking you want to include. This must match the other device(s) on the network.
Stop Bits: Select the number of stop bits. This must match the other device(s) on the network.
Flow Control: Choose None or Hardware (RTS/CTS). This must match the other device(s) on the network.
