USER MANUAL MODEL 1004 and 1004S High Speed, Multipoint Short Range Modem Part# 07M1004-C Doc# 047011UC Revised 8/10/95 SALES OFFICE (301) 975-1000 TECHNICAL SUPPORT (301) 975-1007
1.0 WARRANTY INFORMATION 2.0 GENERAL INFORMATION Patton Electronics warrants all Model 1004 components to be free from defects, and will—at our option—repair or replace the product should it fail within one year from the first date of shipment. This warranty is limited to defects in workmanship or materials, and does not cover customer damage, abuse or unauthorized modification. If this product fails or does not perform as warranted, your sole recourse shall be repair or replacement as described above.
.0 CONFIGURATION The Model 1004 is configured using six PC board mounted switches. Figure 1 shows the switch locations, along with the location of the terminal blocks and optional surge protectors: DCE/DTE Switch Surge Suppressors (1004S only) 2-Wire/4-Wire Switch 3.2 ACCESSING THE CONFIGURATION SWITCHES The five switches shown in Figure 3 configure the Model 1004 for RTS/CTS delay, echo, method of carrier control, impedance and 2-wire/4-wire operation.
3.2.1 SWITCH SETTINGS SW 1-4: Impedance All possible settings for the Model 1004’s configuration switches are presented in the summary table below. If you have additional questions, contact Technical Support at (301) 975-1000.
4.0 INSTALLATION 3. Strip the insulation on each of the twisted pair wires about .25”. Once the Model 1004 is properly configured, it is ready to connect to your system. This section tells you how to properly connect the Model 1004 to the twisted pair and RS-232 interfaces, and how to operate the Model 1004. 4.1 TWISTED PAIR CONNECTION The Model 1004 supports data-only communication between two RS-232 devices at distances to 9.4 miles and data rates to 115.2 Kbps.
8. When you finish connecting the wires to the terminal block, the assembly should resemble the diagram below: 10. Insert the strain relief assembly and wire into the slot in the bottom half of the modem case. Set it into the recess in the case. +RCV- G -XMT+ 9. 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.
4.1.2 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45 RJ-45 Cable (4-Wire) The RJ-11 and RJ-45 connectors on the Model 1004’s twisted pair interface are pre-wired for a standard TELCO wiring environment. The signal/pin relationships are shown below: RJ-11 SIGNAL RJ-45 1 ...................GND† 2 ...................RCV3 ...................XMT+ 4 ...................XMT5 ...................RCV+ 6 ...................GND † SIGNAL 1 ...................N/C 2 ...................GND 3 ...................RCV4 ..
Figure 4 shows how to wire the two-pair cables properly for a Model 1004 star topology. Note that the ground connection is not needed. HOST XMT+ XMT- RCV+ FIRST SLAVE RCV+ SECOND SLAVE RCV+ 4.3 CONNECTION TO THE RS-232 INTERFACE RCV- Once you have properly configured the Model 1004 and connected the twisted pair wires correctly, simply plug the Model 1004 directly into the DB-25 port of the RS-232 device. Remember to insert and tighten the two captive connector screws.
