Installation - Black Box SHM-NPR/RJ-45 Series Manual

SHM NPR/RJ-45
The SHM plugs directly into the back of a terminal or
computer. This eliminates the need for an RS-232C data
cable. No power is required from an external source
because the unit is powered entirely by the terminal or
computer's control and data signals.
The SHM has an interface connection at each end, one
for DTE or DCE, and one for the telephone line
(twisted pairs). To install the SHM:
1. Connect the twisted-pair cable (customer-supplied) to
the RJ-45 female. Refer to Figure 3-1 for the
associated pin assignments.
2. When the SHM has been cabled, connect the
telephone-interface cable to the telephone outlet.
