When connecting two Model 1010As, it is necessary to use a

"cross over" cable. The diagram below shows how a cross over cable should be constructed for an environment where both Model 1010As use a 6-wire RJ-11 connector. Similar logic should be followed when using RJ-45 connectors or a combination of the two.

4.1.2 TWISTED PAIR CONNECTION USING TERMINAL BLOCKS

If your RS-422 application requires you to connect two pairs of bare wires to the Model 1010A, you will need to open the case to access the terminal blocks. The following instructions will tell you how to open the case, connect the bare wires to the terminal blocks, and fasten the strain relief collar in place so that the wires won't pull loose.
