3.On the Model 457B PC board (see figure 2, below), locate the jumper blocks corresponding to each RJ-45 port. They are labeled JP1 - JP8. As figure 3 (below) shows, each jumper block has 16 pins and two jumpers.

4.Having located the jumper blocks for the ports you need to re- configure, set the jumpers for TIP and RING according to the table below. For example, placing the TIP jumper on jumper pins 5 and 6 activates RJ-45 pin 3. Placing the RING jumper on jumper pins 11 and 12 activates RJ-45 pin 6. The resulting configuration for that RJ-45 port would be TIP-3, RING-6.

TIP Jumper Pins	Active RJ-45 Pin
1 & 2	1
3 & 4	2
5 & 6	3
7 & 8	4	(default setting)

RING Jumper Pins	Active RJ-45 Pin
9 & 10	5	(default setting)
11 & 12	6
13 & 14	7
15 & 16	8

5.After you have repositioned the jumpers, slide the PC board back into the case and replace the two Phillips screws.

4.0 INSTALLATION

After the internal jumpers are configured for your equipment, you are ready to connect up the Model 457B. This section explains how to connect the host and terminals to the Model 457B in a star topology using twisted pair cable.

4.1 CONNECTION TO THE HUB

Host Connection—The host port of the Model 457B allows RJ-45 or terminal block connection of a single twisted pair cable. The maximum distance between the Model 457B and the host is 2250 feet. Only one host may be connected to the hub at a time.

Terminal Connections—RJ-45 ports 00 - 06 on the Model 457B allow connection of up to seven terminals using single pair cable. The maximum distance between the Model 457B and each terminal is 2250 feet. Note: Pin-outs of RJ-45 cables must match the pin configurations chosen for the Model 457B's ports (see Section 3.0 for more details).

4.2 CONNECTION TO HOST AND TERMINAL HARDWARE

Most AS/400 and System 3X hardware is equipped with twinax ports, and is set up to communicate over twinax cable. In order to communicate over a single twisted pair, you must use a twinax to twisted pair adapter or "BALUN" at each host and terminal connection. The Patton Model 410 Series Twinax Balun is 100% compatible with the Model 457B, and is highly recommended for this application. Model 410 baluns are available for RJ-11, RJ-45, or terminal block twisted pair connection. Figure 4 (below) illustrates wiring for a star network using one Model 457B hub and eight Model 410 baluns.
