9 Serial Communication
The 5232 controller board is equipped with three serial communication ports. Each of the four serial
communication ports support RS-232 serial communication and one port supports both RS-232 and
RS-485 serial communication. The integrated I/O module provides additional serial communication
capabilities. Please refer to the section of the manual for each respective I/O module for details.
Port Type Description
COM1 RS-232-485 R-J45 connector designated P6 on the 5232 Controller.
COM2 RS-232 RJ-45 connector designated P7 on the 5232 Controller.
COM4 RS-232 RJ-45 connector designated P8 on the 5232 Controller.
9.1 RS-232 Serial Communication Ports
All RS-232 wiring must use shielded cable. The shield should be connected to chassis ground at one
point. Failure to properly shield the cable may result in the installation not complying with FCC or
DOC radio interference regulations.
9.1.1 COM1
Serial port COM1 may be configured as an RS-232 or RS-485 serial communication port.
• A jumper must be installed on J10 to operate COM1 in RS-232 mode.
• A jumper must be installed on J9 to operate COM1 in RS-485 mode.
Note: For configuration of serial port type in TelePACE or ISaGRAF, RS-232 is used for either
mode of operation i.e. for RS-232 or RS-485 mode.
Refer to the drawing in Figure 1: 5232 Controller Board Layout for the location of COM1 and
jumpers J9 and J10.
For information on using COM1 as a RS-485 serial port refer to section 9.6-RS-485 Serial
Communication Port subsection.
Connections to COM1 are made through a RJ-45 modular connector. Connections are made through
a DE-9P connector. The wiring and pin connections for this connector are described in section 9.3-
DE-9P Connector for RS-232.
The following table shows the serial and protocol communication parameters supported by COM1.
These parameters are set from the ISaGRAF Workbench or from an application program running in
the SCADAPack 32 controller. Default values are set when a Cold Boot or Service Boot is
performed on the SCADAPack 32 controller.
