XU-A11 XA-A14 cable replacement, Getting response lag, what settings are involved?

I’m using the modules as a cable replacement. I send a 21 byte packet from the usb stick, and should receive a 21byte packet back from the converter module almost immediately. The problem occurring is I’m getting a severe response delay. I cannot change my program to adjust for those timings. On the hand somebody asks, I use a Zigbee unit set from Sena Industrial and it works amazingly well. I was hoping the Digi unit would work as well so I have two sources for these types of modules.

Try setting the addressing on the Xstick to Unicast by setting the DL and DH of the XStick to match the SL and SH of the RS485 adapter.
