4.0 INSTALLATION
Once you have properly configured the DTE/DCE switch, you are
ready to connect the Model 1010B to your system. This section tells
you how to properly connect the Model 1010B to the twisted pair and
RS-232 interfaces, and how to operate the Model 1010B.
4.1 CONNECTION TO THE TWISTED PAIR INTERFACE
The Model 1010B supports data-only communication between two
RS-232 devices at distances to 8.5 miles and data rates to 115.2 kbps.
There are two essential requirements for installing the Model 1010B:
1.
These units work in pairs. Therefore, you must have one
Model 1010B at each end of a two twisted pair interface.
2.
To function properly, the Model 1010B needs two twisted pairs
of metallic wire. These pairs must be unconditioned, dry
metallic wire, between 19 and 26 AWG (the higher number
gauges may limit distance somewhat). Standard dial-up
telephone circuits, or leased circuits that run through signal
equalization equipment, are not acceptable.
For your convenience, the Model 1010B is available with three
different twisted pair interfaces: RJ-11 jack, RJ-45 jack and terminal
blocks with strain relief.
4.1.1 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45
The RJ-11 and RJ-45 connectors on the Model 1010B's twisted pair
interface are pre-wired for a standard TELCO wiring environment. The
signal/pin relationships are shown below.

3.2 “NORMAL” vs. “MODEL 1010 COMPATIBLE” OPERATION
The table below shows jumper settings, including factory defaults.
Important: When using the Patton Model 1010B with an older
Patton Model 1010, you must set the jumpers for Model 1010
compatible operation.
Jumper JP2
Jumper JP2 is set in conjunction with jumper JP3 to place the
Model 1010B in either “Normal” or “Model 1010 compatible” operating
mode. For the Normal (factory default) setting, jumper JP2 should be
placed on only one of the two pins. This is defined as “jumper OFF.”
For the 1010 compatible setting, jumper JP2 should be placed on both
of the pins. This is defined as “jumper ON.”
Jumper JP3
Jumper JP3 is set in conjunction with jumper JP2 to place the
Model 1010B in either Normal or Model 1010 compatible operating
mode. For the Normal (factory default) setting, jumper JP3 should be
placed on pins 2 and 3 (see Figure 3, below). For the Model 1010
compatible setting, jumper JP3 should be placed on pins 1 and 2 .
“Jumper OFF” is not a valid option.
