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.
3.2 SETTING THE DCE/DTE SWITCH Correct setting of the DCE/DTE switch eliminates the need for RS- 232 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".

4.1.2 TWISTED PAIR CONNECTION USING RJ-11 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.
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.
