3-2 Mounting the Host Link Unit
Mounting Position Up to four CV500-LK201 Host Link Units can be mounted to any of the slots on a
CV-series CPU Rack or Expansion CPU Rack except when the CVM1-BC103 or
CVM1-BC053 Backplane is used. On a CVM1-BC103 Backplane, Host Link
Units must be mounted to the rightmost 6 slots; on a CVM1-BC053 Backplane,
the rightmost 3 slots.
3, 5, 6, or 10 slots
CPU Rack
The slots that Host Link Units can be mounted to varies with the
model of CPU Backplane as follows:
CV500-BC031: Any slots (3 slots total)
CV500-BC051: Any slots (5 slots total)
CV500-BC101: Any slots (10 slots total)
CVM1-BC103: Rightmost 6 slots only
CVM1-BC053: Rightmost 3 slots only
Expansion CPU Rack
It is possible to mount Host Link Units to any of the 11 slots.
(An Expansion CPU Rack cannot be connected to a CPU
Rack using a CVM1-BC053/103 Backplane.)
Expansion I/O Rack
Host Link Units can not be mounted to an Expan-
sion I/O Rack.

The maximum current consumption of the Host Link Unit is 600 mA if an optical
interface is not used. If 5 V is supplied when using an optical interface, however,
the current consumption increases by 100 mA. When using the Host Link Unit
with other Units, make sure that the actual current consumption of the Host Link
Unit does not exceed the total permissible current consumption (refer to the CV-
series PC Installation Guide for details).
The Host Link Unit weighs 550 g maximum.
3-3 Connection Cables for the Host Link Unit
Basic cable wiring procedures are described in 3-9 Wiring. Details and exam-
ples are provided in the remaining subsections of Section 3.
Port 1 supports only RS-232C connections, which are described in the next sub-
section.
To connect to a Programmable Terminal (PT), you will need to prepare a cable
according to the information on page 37.
