Installation Instructions ArmorPoint I/O RS-485 ASCII Module, Series A (Cat. No. 1738-485ASCM12) The ArmorPoint I/O family (Cat. no. 1738) consists of modular I/O modules. The sealed IP67 housing of these modules requires no enclosure. (Note that environmental requirements other than IP67 may require an additional appropriate housing.) The I/O connector is a sealed M12 (micro) style. The mounting base ships with the module. The 1738-485ASCM12 module is shown below.
ArmorPoint I/O RS-485 ASCII Module, Series A Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.ab.com/manuals/gi) describes some important differences between solid state equipment and hard-wired electromechanical devices.
ArmorPoint I/O RS-485 ASCII Module, Series A ATTENTION 3 Environment and Enclosure This equipment is intended for use 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.
ArmorPoint I/O RS-485 ASCII Module, Series A Preventing Electrostatic Discharge ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards. • Do not touch circuit components inside the equipment.
ArmorPoint I/O RS-485 ASCII Module, Series A 5 Install the mounting base as follows: 1. Lay out the required points as shown above in the drilling dimension drawing. 2. Drill the necessary holes for #8 (M4) machine or self-tapping screws. 3. Mount the base using #8 (M4) screws. 4. Ground the system using the ground lug connection. (The ground lug connection is also a mounting hole.
ArmorPoint I/O RS-485 ASCII Module, Series A Install the ArmorPoint RS-485 ASCII Module To install the ArmorPoint RS-485 ASCII module, proceed as follows. 1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number 2 aligns with the notch in the base. 2. Position the module vertically above the mounting base. The module will bridge two bases. Module will bridge two bases. 1738-485ASCM12/A ASCII Interface MOD NET TxD RxD 43802 3.

This should be considered when choosing shielded cables and grounding techniques.
ArmorPoint I/O RS-485 ASCII Module, Series A Communicate With Your Module The ASCII module operates as the PointBus front-end to your serial device. Data can be exchanged with the master through a polled, cyclic, or change of state connection. The module produces and consumes 4 to 132 bytes of data.
ArmorPoint I/O RS-485 ASCII Module, Series A Indication Probable Cause Flashing Red One or more I/O connections in timed-out state. Red Critical link failure - failed communication device. Device detected error that prevents it from communicating on the network. Flashing Red/Green Communication faulted device - the device has detected a network access error and is in communication faulted state. Device has received and accepted an Identity Communication Faulted Request - long protocol message.
