Installation Instructions

INTRODUCTION The 485 Interface module from Siemens Building Technologies, Inc. is a component of

the HUB-4 assembly. Each 485 Interface module provides 1 independent data

channel. The HUB-4 can support up to 4 independent data channels. The 485 Interface

module mounts on the HUB-4, COM-2 board, which in turn mounts on the HUB-4

Main-2 board. Refer to the table below to determine the required modules for the

desired configuration.

INSTALLATION Disconnect BATTERY and AC prior to working on equipment. Mounting Each 485 Interface module mounts to a HUB-4, COM-2 with the 3 nylon spacers, 3 nylon screws, and 3 nylon washers provided. One HUB-4, COM-2 board can accommodate up to 2 485 Interface modules. 1. To begin mounting a 485 Interface module on a HUB-4, COM-2 board, place the screw end of the 3 spacers through the holes in the top of the COM-2 board. (Refer to Figure 2.) 2.
