3.0 CONFIGURA TION The Model 1025 provides six configuration switches which allow selection of clocking method, RTS/CTS delay and data rate. This sec- tion describes switch locations and explains all possible switch config- urations.
3.2 SWITCH SETTINGS All possible settings for the Model 1025’s configuration switches are presented in the summary table and descriptions below . If you have additional questions regarding configuration, contact Patton T echnical Support at (301) 975-1007.
When connecting two Model 1025s, it is necessary to use a “crossover” cable. The diagram below shows how a crossover cable should be constructed for an environment where both Model 1025s use a 6-wire RJ-1 1 connector . Similar logic should be followed when using RJ-45 connectors or a combination of the two.
1. Open the unit by gently inserting a screwdriver between the DB-25 connector and the lip of the plastic case (see below). Y ou don’t have to worry about breaking the plastic, but be careful not to bend the D-sub connector . Once the unit has been opened, you will be able to see the terminal blocks located at the rear of the PC board.
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.
