RS485/422 with Portserver TS 2 MEI: Maximum no. of node and comminication distance

I intent to use Portserver TS 2 MEI to connect Elster A1700 meters via RS422 multi-drop connection. The serial port in TCP profile. But I have more than 32 meter in RS422 bus.
Can I use commonly used RS485/422 repeater (ex: Moxa’s device) to increase number of node on communication bus and extend communication distance.
In standard case (do not use repeater), what is the maximum number of RS485 note and maximum communication distance that portserver TS 2 MEI can support?
Best and Regards,
