Do the Jace-6 or Jace-7 need multiple Modbus drivers if more than one port is used?

Issue

The jobsite will eventually have 4 RS-485 trunks each communicating Modbus.  Two option cards have been ordered with the Jace (part# TRD-NPB-2X-485).
Does each port on the option cards need a separate Modbus driver purchased for each?

Resolution

Purchasing one Modbus driver (part# ENC-DRV-MOD) will cover all ports used for Modbus on the Jace-6/7.
