1. For your convenience the Model 1010A has an externally accessible DCE DTE switch see figure below If the device connected to the Model 1010A is a modem or multiplexer or is wired like one set the switch to DTE This setting causes the Model 1010A to behave like Data Terminal Equipment and transmit data on pin 2 If the device connected to the Model 1010A is a PC terminal or host computer or is wired like one set the switch to DCE This setting causes the Model 1010A to behave like Data Communications Equipment and transmit data on pin 3 DCE J DTE 4 0 INSTALLATION Once you have properly configured the DTE DCE switch you are ready to connect the Model 1010A to your system This section tells you how to properly connect the Model 1010A to the twisted pair and RS 232 interfaces and how to operate the Model 1010A 4 1 CONNECTION TO THE TWISTED PAIR INTERFACE The Model 1010A supports data only communication between two RS 232 devices at distances to 8 5 miles and data rates to 115 2 Kbps There are two essential requirements for installing the Model 1010A 1 These units work in pairs Therefore you must have one Model 1010A at each end of a two twisted pair interface 2 To function properly the Model 1010A 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 telephon2. Note If you must use a cable to connect the Model 1010A 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 1010A Once the Model 1010A is properly 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 1012 or Model 1060 Short Range Modem Call Patton Customer Service at 301 975 1007 for more information 8 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 If your cable diameter is too small or too large for our strain relief please contact our technical support We have strain relief assemblies to accommodate most cable diameters E Som FC roy Cy 2 Sari CE 9 9 E x Ji odlg 9 Insert the strain relief assembly with th
