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.

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: (301) 975-1007;
