HUB-4 Configuration
The HUB-4 can be configured to support from one to four independent communica-
tion channels (Modem Block or RS-485 Interface modules). Refer to Table 3 to
determine the required modules for the desired configuration. Modem Block and RS-
485 Interface modules can not be mixed on a single COM-2 card.

HUB-4 Assembly
The HUB-4 Assembly consists of the HUB-4 Main-2, two COM-2 boards, and from
one to four Modem Block or RS-485 Interface modules, depending on your desired
configuration. If your HUB-4 is preassembled, complete Steps 1 and 2 below and then
go to Step 9. Refer to Table 4 for correct placement of modem block or RS-485 Inter-
face modules on the HUB-4 Main -2.
When assembling the HUB-4, note that P1, the 2 X 15 receptacle on the HUB-4, Main-2, connects
to Port 1, P2 connects to Port 2, P3 connects to Port 3, and P4 connects to Port 4.
1.
Begin connecting the components by following the instructions for the
Modem Block module, P/N 315-099356, or the RS-485 Interface module, P/
N 315-049930.
2.
Determine the number of channels (from one to four) that your system will
require. Install the HUB-4 COM-2 and Modem Block or RS-485 Interface
modules on the HUB-4 Main-2 according to Table 4, page 6.
