2.0 GENERAL INFORMATION 3.0 CONFIGURATION Thank you for your purchase of this Patton Electronics product. This product has been thoroughly inspected and tested and is warranted for One Year parts and labor. If any questions or problems arise during installation or use of this product, please do not hesitate to contact Patton Electronics Technical Support at (301) 975-1007. The Model 1050 may be configured for a wide variety of asynchronous RS-232 applications.
.0 INSTALLATION 3.2 SETTING THE DCE/DTE SWITCH Correct setting of the DCE/DTE switch eliminates the need for RS232 crossover cables. If the RS-232 device you are connecting to the Model 1050 is a PC, terminal or host, or is wired like one, set the DCE/DTE switch to "DCE". If the RS-232 device you are connecting to the Model 1050 is a modem or multiplexer, or is wired like one, set the DCE/DTE switch to "DTE". 3.
4.1.2 TWISTED PAIR CONNECTION USING RJ-11 4.2 WIRING FOR MULTIPOINT CIRCUITS If your two-pair cable is terminated in an RJ-11 plug, you may use the RJ-11 jack in the back of the Model 1050 to make the connection. The RJ-11 jack on a Model 1050 series Short Range Modem is prewired for a standard TELCO wiring environment. To be sure you have the right wiring, use the diagram below as a guide. The Model 1050 supports multi-point applications using either a star or daisy chain topology.
5.0 OPERATION 4.2.2 STAR TOPOLOGY Using a star topology, you may connect several Model 1050s together in a master/slave arrangement. Maximum distance between the units will vary based upon the number of drops, data rate, wire gauge, etc. Call Patton Technical Support for specific distance estimates. Figure 4 (below) shows how to wire the two-pair cables properly for a Model 1050 star topology. Note that the ground connection is not needed.
APPENDIX A 5.2.2 REMOTE ANALOG LOOP PATTON MODEL 1050 SPECIFICATIONS The second test mode is Remote Analog Loop. To enter this mode, set one of the Model 1050s (local) in test mode by depressing the "Loopback Test" switch. Any characters sent from the remote 1050 will be returned to it (see Figure 5). If no characters are echoed back, check the wiring between the two Model 1050s. Be sure to wire the units according to the instructions in Section 4.0 Installation.
