To attach MPC Open XPIO expanders
1
Wire the MPC Open XP's Xnet Remote Expansion port to the same port on the expander.
Connect:
Gnd to Gnd
○
Xnet- to Xnet-
○
Xnet+ to Xnet+
○
NOTE To use more than one expander, wire their Xnet Remote Expansion ports together in a daisy-chain
configuration. The MPC Open XP must be the first device on the expander network.
2
Set the Xnet baud rate to 500 kbps in the i-Vu® interface on the driver's Xnet page.
3
If the expander network has more than one expander, place the Term jumper in the down position or remove
it from all expanders except the one at the end of the expander network. The Term jumper must be in the up
position on the expander at the end of the network.
To set expander's address
You must give the expanders an address that is unique on the expander network.
1
If wired for power, turn off the expander's power and the attached MPC Open XP's power.
2
Set the expander's address on the rotary switch.
EXAMPLE If the controller's address is 2, point the arrow on the switch to 2.
NOTE The MPC Open XP can have a maximum of 3 expanders. You MUST address the expanders as 1, 2,
and 3. Higher addresses will not work.
3
Turn on the expander's power, then turn on the attached MPC Open XP's power. The MPC Open XP reads the
powered expander's address each time you turn on the MPC Open XP.
CAUTION The first time the controller communicates with an expander, it triggers a software download. This
may occur if the expander(s) are blank (not a normal condition) and in cases where the controller's driver has
been updated. During that time, the red Error LED and the green Run LED on the expander(s) flash in sequence.
This process may take several minutes to complete. Do not disconnect power or communications wiring during
this download.
