Serial to Ethernet

I recently purchased a MAX-BR1-MINI-LTE-US-T-PRM (H3) and was hoping to use the ACW-411 Serial adapter to setup communication with a serial device. When I start confuring the device, I noticed that the new device did not have the UART Serial to Ethernet settings. My existing devices (MAX-BR1-MINI-LTE-US (H1)) do have this functionality. Can someone help me? Does the MAX-BR1-MINI-LTE-US-T-PRM (H3) not support the ACW-411 adapter and serial to ethernet settings??

@Jordan_Harrell, a similar question has been asked in another thread, and I see there are responses posted.
