2.2 DESCRIPTION

The Patton Model 1010B miniature, high speed, transformer

isolated short range modem lets two asynchronous RS-232 devices
communicate between buildings, over two twisted pair. Supporting
asynchronous data rates to 115.2 kbps, the Model 1010B derives the
necessary power for operation from the data and control voltages on
the RS-232 interface. DC transformer isolation on the line side gives
the Model 1010B immunity to ground loops that would otherwise
hamper between-building communications.

An external DCE/DTE switch lets you connect to the serial port of
either a computer/terminal (DTE) or a modem (DCE) without using a
crossover cable. The Model 1010B is available with three 4 wire
interface options: RJ-11, RJ-45 or terminal blocks with strain relief.

3.0 CONFIGURATION

The Model 1010B also incorporates high speed avalanche diodes
that intercept data line transient surges and shunt them safely to
chassis ground. With surge handling capacity of 600W per wire at
1mS, the 1010B can protect itself and connected equipment from
nearby lightning strikes and other surges of electromagnetic radiation.

The Model 1010B is configured using an external DCE/DTE switch
and two internal jumpers (the factory jumper settings are appropriate for
most applications). This section describes the configuration switch and
jumpers and shows factory defaults. Figure 1 below shows the location
of the switch/jumpers on the Model 1010B’s internal PC board.

3.1 SETTING THE DTE/DCE SWITCH

For your convenience, the Model 1010B has an externally
accessible DCE/DTE switch (see Figure 2, below). If the device
connected to the Model 1010B is a modem or multiplexer (or is wired
like one), set the switch to "DTE." This setting causes the Model 1010B
to behave like Data Terminal Equipment and transmit data on pin 2.

If the device connected to the Model 1010B is a PC, terminal or
host computer (or is wired like one), set the switch to "DCE." This
setting causes the Model 1010B to behave like Data Communications
Equipment and transmit data on pin 3.

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 mustset 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.

When connecting two Model 1010Bs, it is necessary to use a
"cross over" cable. The diagram below shows how a cross over cable
should be constructed for an environment where both Model 1010Bs
use a 6-wire RJ-11 connector. Similar logic should be followed when
using RJ-45 connectors or a combination of the two.

4.1.2 TWISTED PAIR CONNECTION USING TERMINAL BLOCKS

If your application requires you to connect two pairs of bare wires
to the Model 1010B, you will need to open the case to access the
terminal blocks. The following instructions will tell you how to open the
case, connect the bare wires to the terminal blocks, and fasten the
strain relief collar in place so that the wires will not pull loose.

1. Open the unit by gently inserting a screw driver between the
DB-25 connector and the lip of the plastic case (see Figure 5,
below). You don't have to worry about breaking the plastic, but
be careful not to bend the D-sub connector.

Once the unit has been opened, you will be able to see the
terminal blocks located at the rear of the PC board.

2. Remove the insulation from the twisted pairs about one inch
from the end.

3. Remove the insulation on each of the 2 twisted pair wires
about .25".

4. Connect one pair of wires to XMT+ and XMT- (transmit
positive and negative) on the terminal block, making careful
note of which color is positive, and which color is negative.

5. Connect the other pair of wires to RCV+ and RCV- (receive
positive and negative) on the terminal block, again making
careful note of which color is positive, and which color is
negative.

8

Construct a two pair cross over cable that makes a connection
between the two short range modems as shown below.

6. If there is a shield around the telephone cable, it may be
connected to "G" on the terminal block. To avoid ground
loops, connect the shield at the computer end only. A ground
wire is not necessary for proper operation of the Model
1010B.

7. Refer to the diagram below to confirm that you have correctly
assembled the device.

8. Place the 2 halves of the strain relief assembly on either side
of the telephone wire and press together very lightly. Slide the
assembly so that it is about 2 inches from the terminal posts
and press together firmly. If your cable diameter is too small or
too large for our strain relief, please contact our technical
support. We have strain relief assemblies to accommodate
most cable diameters.

11. Insert one captive screw through a saddle washer, then insert
the captive screw with the washer on it through the hole in the
DB-25 end of the case. Snap that side of the case closed.
Repeat the process for the other side. This completes cable
installation.

4.2 CONNECTION TO THE RS-232 INTERFACE

Once you have configured the Model 1010B for DTE or DCE and
connected the twisted pair wires correctly, all that remains is to plug the
1010B directly into the DB-25 port of the RS-232 device. After doing so,
remember to insert and tighten the two captive connector screws.

(Note: If you must use a cable to connect the Model 1010B to the
RS-232 device, make sure it is a

straight through

cable of the shortest

possible length—we recommend 6 feet or less).

4.3 OPERATING THE MODEL 1010B

Once the Model 1010B is properly installed, it should operate
transparently—as if it were a standard cable connection. Operating
power is derived from the RS-232 data and control signals; there is no
"ON/OFF" switch. All data signals from the RS-232 interface are
passed straight through. All control signals from the RS-232 interface
are looped back.

NOTE: If your system requires hardware flow control, you will

need the Patton Model 1012 Modem or Model 1060 Short Range

Modem. Call Patton Technical Services at: [phone];
