General characteristics
1.9 H-LINK
HC-A64NET is compatible with the H-LINK 2 and the old version called H-LINK (H-LINK 1) units.
Connection of both H-LINK 1 and H-LINK 2 units in the same H-LINK unit is possible considering the unit limitations and addressing.
H-LINK 2 number of connectable devices is up to a maximum of 200 devices in the H-LINK 2 line. A CSNET WEB, an Indoor Unit,
an Outdoor Unit, a HC-A64NET or other devices with H-LINK address are considered as a device.

N O T E
• CSNET Manager is not considered as an H-LINK device.
• PC-A1IO, KPI or DX-Kit count as a normal indoor unit.
When there is a central control device like CSNET Manager, the maximum number of total units (indoor and outdoor units) for only
1000 meters of H-LINK line is shown on the following table:
H-LINK line length could be up to 1000 meters, they could be increased to 5000 meters using up to 4 PSC-5HR. Each of them adds
1000 meters to the line, affecting the quantity of indoor unit that can be connected to the same H-LINK.
Each H-LINK line repeater (PSC-5HR) counts as 16 indoor units. The following table summarize the affection of the PSC-5HR to the
indoor and outdoor unit maximum number.

Therefore, considering the previous maximums and the number of PSC-5HR, the maximum number of indoor units with one central
control, on that case CSNET WEB, is shown on the following table and graphic.
Outdoor units
0 PSC-5HR
1 PSC-5HR
2 PSC-5HR
3 PSC-5HR
4 PSC-5HR
The maximum number of Indoor units connectable to a HC-A64NET is 64, and for the outdoor units are 64.
Note that CSNET Manager connected to a PSC-A160WEB1 can control up to 160 units. Connecting 8 PSC-A160WEB1 to one
CSNET Manager we can get the maximum number of connectable units of 1280.
