RS-485 Enable High on 8003 firmware

For the firmware 8003 that is currently available at the Digi website, I’d would like to know how I can enable RS485 High. The D7 parameter under the Serial interfacing option only has “RS-485 Enable” option, but does not specify if it is high or low. I need to enable RS-458 high for my application. Is there anything that can solve this problem?

Looking in the OEM manual for DM 2.4 in the AT Command reference section, I find the following for the D7 command:

6 = RS-485 Tx enable, low TX (0V on transmit, high when idle)
7 = RS-485 Tx enable, high TX (high on transmit, 0V when idle)

Correction. Upgrade not available at this point.
