Compact 1769-ASCII Module Important User Information Because of the variety of uses for the products described in this publication, those responsible for the application and use of these products must satisfy themselves that all necessary steps have been taken to assure that each application and use meets all performance and safety requirements, including any applicable laws, regulations, codes and standards.
Compact 1769-ASCII Module 3 IMPORTANT ATTENTION Identifies information that is critical for successful application and understanding of the product. Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
Compact 1769-ASCII Module About the Module The 1769-ASCII module provides a flexible network interface to a wide variety of RS-232, RS-485, and RS-422 ASCII devices. The module provides the communication connections to the ASCII device.
Compact 1769-ASCII Module 5 Install the Module Compact I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution Degree 2(1)) and to circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3) ATTENTION Preventing Electrostatic Discharge This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation.
Compact 1769-ASCII Module ATTENTION This product is grounded through the DIN rail to chassis ground. Use zinc-plated, yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (e.g., aluminum, plastic, etc.), which can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Assemble the System Attach the module to the controller or an adjacent I/O module before or after mounting.
Compact 1769-ASCII Module 7 1. Disconnect power. ATTENTION Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by: • sending an erroneous signal to your system’s field devices, causing unintended machine motion • causing an explosion in a hazardous environment Electrical arcing causes excessive wear to contacts on both the module and its mating connector.
Compact 1769-ASCII Module 7. Attach an end-cap terminator (5) to the last module in the system by using the tongue-and-groove slots as before. 8. Lock the end-cap bus terminator (6). You must use a 1769-ECR or -ECL right- or left-end cap to terminate the end of the serial communication bus. IMPORTANT Mount Expansion I/O ATTENTION During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, etc.) is kept from falling into the module.
Compact 1769-ASCII Module 9 Panel Mount Mount the module to a panel by using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module. Panel Mount Procedure With the Dimensional Template Compact I/O Right End Cap 28.5 (1.12) 35 (1.38) Compact I/O 122.6±0.2 (4.826±0.008) Compact I/O 132 (5.197) Host Controller For more than 2 modules: (number of modules - 1) X 35 mm (1.38 in.) Refer to host controller documentation for this dimension.
Compact 1769-ASCII Module 5. Place the modules back on the panel, and check for proper hole alignment. 6. Attach the modules to the panel using the mounting screws. If mounting more modules, mount only the last one of this group and put the others aside. This reduces remounting time during drilling and tapping of the next group. 7. Repeat steps 1 to 6 for any remaining modules. Mount on the DIN Rail The module can be mounted on these DIN rails: • 35 x 7.5 mm (EN 50022 - 35 x 7.
Compact 1769-ASCII Module 11 Replace a Single Module Within a System The module can be replaced while the system is mounted to a panel or DIN rail. 1. Remove power. ATTENTION Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur.
Compact 1769-ASCII Module 6. Before installing the replacement module, be sure that the bus lever on the module to be installed and on the right-side adjacent module are in the unlocked (fully right) position. 7. Slide the replacement module into the open slot. 8. Connect the modules together by locking (fully left) the bus levers on the replacement module and the right-side adjacent module. 9. Replace the mounting screws (or snap the module onto the DIN rail).
Compact 1769-ASCII Module 13 Connect the D-sub Connector Pins All pins are active at all times. IMPORTANT Pins unused for a particular physical network must not be connected via the serial cable to any other device. In particular, do not use cables 1747-CP3 and 1756-CP3.
