6. NNECTION USING TERMINAL BLOCKS If your application requires you to connect two pairs of bare wires to the Model 1025 you will need to open the case to access the termi nal blocks The instructions on the following pages will tell you how to open the case connect the bare wires to the terminal blocks and fas ten the strain relief collar in place so that the wires won t pull loose Open the unit by gently inserting a screwdriver between the DB 25 connector and the lip of the plastic case see below You 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 Strip the outer insulation from the twisted pairs about one inch from the end E lt ceil Strip back the insulation on each of the 2 twisted pair wires about 25 Connect one pair of wires to the two XMT transmit poles on the terminal block The Model 1025 is not polarity sensitive so either wire may connect to either pole Connect the other pair of wires to the two RCV receive poles on the terminal block The Model 1025 is not polarity sensi tive so either wire may connect to either pole Ultimately you will want to construct a two pair crossover cable that makes a connection with the two Model 1025s as shown below I ee ie aries ec terete RCV One Pair XMT RCV Gi seeas
