1. 2 interfaces and how to operate the Model 1020 4 1 CONNECTION TO THE TWISTED PAIR INTERFACE The Model 1020 supports data only communication between two RS 232 devices at distances to 11 miles and data rates to 19 2 Kbps There are two essential requirements for installing the Model 1020 1 These units work in pairs Therefore you must have one Model 1020 at each end of a two twisted pair interface 2 To function properly the Model 1020 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 1020 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 Ru 11 and RJ 45 connectors on the Model 1020 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 SIGNAL Wsssaces castes sscais GNDt EET N C Oi iisctasnctinaeatie RCV PA E GNDt e E XMT O ariris iega RCV C ESEA XMT E XMT E E RCV Dinane XMT Oissvenictecesste GND O cesccsthcoesaeias RCV T soaa GND le ETE N C tConnection to ground is optional The Model 1020 is not polarity sensitive When2. E RS 232 INTERFACE Once you have connected the twisted pair wires correctly simply plug the Model 1020 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 1020 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 1020 Once the Model 1020 is properly configured and 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 1030 or Model 1070 Short Range Modem Call Patton Customer Service at 301 975 1007 for more information 11 APPENDIX A SPECIFICATIONS Transmission Format Synchronous full duplex Transmission Line Two unconditioned twisted pair 19 26 AWG Range See table below Interfaces EIA RS 232 CCITT V 24 Data Rates 1200 19 2 Kbps Isolation Minimum 1500 V RMS via custom transformers Surge Protection 600W Surge Protection 10x1000us waveform Model 1020S Control Signals CTS turns on 7 or 53 mS switch selectable after the terminal
