RS485 Half Duplex Autogating Mode (ES-357 Only)

For the RS422/485 port on the ES-357, there is an additional tab in the Advanced Settings of the

Windows COM port to allow you to change duplex mode to half duplex autogating mode. The factory

default setting is RS422 full-duplex mode.

When the duplex mode is set to half duplex autogating the ES device will automatically detect the

start of the PC‟s transmissions and will gate the PC‟s transmitter onto the twisted pair cable. It will

then automatically detect the stop bit being sent and gates the port off the twisted pair cable.

To open RS422/485 settings:

1. Double click the port entry in Boost.LAN Manager

2. Go to the Port Settings tab

3. Click Advanced

4. Go to the RS422/485 Settings tab.

5. The drop down list allows users to choose the desired RS422/485 operations mode.

6. Select “RS422 full duplex mode” for Full Duplex communications.

7. Select “RS485 half duplex autogating mode” for Half Duplex communications.

Restore Defaults: Pressing this button will reset all settings on this Property Page back to the factory

defaults of this device. The default settings for this Property Page are “RS422 full duplex mode”.
