The Model 1000P meets the requirements for FCC Part 15 (RFI limits for Class A
peripheral devices).
3.0 INSTALLATION
All versions of the Model 1000P plug 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 Model 1000P has an interface connection at each end: one for Data
Terminal Equipment (DTE) or Data Communications Equipment (DCE), and
one for the telephone line (twisted pairs). To install the unit, perform the
following steps.
1.
Connect the twisted pair cable (customer-supplied) to the 4-screw
terminal block (Model 1000PM or 1000PF), RJ11 jack (Model
1000PMRJ11 or 1000PFRJ11), or RJ45 jack (Model 1000PMRJ45
or 1000PFRJ45). Refer to Figure 3 for the associated pin
assignments. End-to-End connections should be matched as shown
in Figure 6.
2.
When the 1000P has been cabled connect the telephone interface
cable to the telephone outlet.
