1. 51 User Notes 52 GCS User MANUAL MicRo AiDE f Balla H sir Mele lonas INTRODUCTION The GCS can be used to periodically update the real time clocks of various Target Devices In most cases it does so by providing a serial data connection with a Target Device that is connected fo one of its Device Ports This capability is the basis for another very useful feature referred to as Device Port Access Mode DPAM DPAM allows the user to access a Target Device through the GCS Once enabled DPAM establishes a completely transparent connection to the Target Device This allows the user to dialog with the device as if a PC were directly attached to its user interface port Figure 4 on page 5 illustrates a typical equipment configuration where DPAM has been made available to local i e on site and remote users Using DPAM The first step in using DPAM is to ensure the correct cable connections and settings are in 7 place as described in the following Except for the Microlok Il can be used to access any Target Device that is connected to the GCS via a Device Port e The DCE DTE Baud rate and bit format settings for the Target Device and Device Port must be correctly matched cannot be used with Target Devices that are synced via SNIP Review the Log entries to determine if the above requirements are correctly established If the Log entries indicate a status of OK f
