IOLINK-PRO
The IOLINK-PRO may be ordered with a 10Base2, 10Base5, or 10BaseT LAN interface.
If this IOLINK-PRO has an ISDN U or S/T Module, it must only be installed in the slot 1
(leftmost position when viewed from the rear of the unit). The slot 2 position may be
unused and covered with a blank panel or may contain another type of module. If a second
WAN module is installed, only one BRI channel will be available for use.

The IOLINK-520 is configured with a 10/100BaseT LAN and either one or two optional
interface modules. The optional modules may be a second LAN (10 BaseT), a second LAN
plus one WAN module, a single WAN module or two WAN modules.
Important: If a second LAN module is installed, it must be in the slot 1 (leftmost position
when viewed from the rear of the unit) to operate. In addition, if only one
optional interface module is installed, it must be in slot 1
Each interface may be changed by simply removing the existing module and installing a new
module. Refer to Appendix D: Servicing Information for information on replacing modules.
