When using MicroFlex e190 with OPT-SIO-1, the termination could be realized with the dip switches on the option module.
When using MicroFlex e150, the termination could be realized with the dip switches at the front side of the drive
No external resistor is needed.

MicroFlex e150
For MicroFlex e100 and NextMove, the termination must be realized externally.
Modbus TCP
When using Modbus TCP / Ethernet, wire the network in a ‘star’ type configuration using an Ethernet switch between the Client
and the connected Server(s). Straight-through or crossover cables may be used between the devices and the switch. If the
controller is part of an Ethernet Powerlink (EPL) network then it is also necessary to include an EPL Router (part: OPT036-501)
or a MicroFlex e190 / MotiFlex e180 drive acting as an EPL router between the switch and the devices (see Application Note
AN00247 for further details).
Note:
AC500 and CP600 products use a non-standard RS232 pinout so be sure to check the relevant product manual before
connecting other serial devices to these products. Failure to observe the correct pinout may result in damage to the connected
device.
