Maximum GPIB-ENET interfaces NI4882 driver can communicate with?

Hi,

The NI-488.2M Reference Manual states that the NI-488.2M driver supports up to four interface boards. Does this limit apply to the GPIB-ENET devices? If not, how many can be communicated with? My particular application needs access to eight GPIB-ENET/1000s.

Thanks

Charles
