4.1.3 4-WIRE CONNECTION USING TERMINAL BLOCKS

If your RS-485 application requires you to connect two pairs of bare wires to the Model 2085, 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.

1.You should already have the case open for the configuration procedure. If not, open the case according to the diagram in Section 3.2.

2.Strip the outer insulation from the twisted pairs about one inch from the end.

3.Strip back the insulation on each of the 2 twisted pair wires about .25".

4.Connect one pair of wires to XMT+ and XMT- (transmit positive and negative) on the terminal block, making careful note of which color is positive, and which color is negative.

5.Connect the other pair of wires to RCV+ and RCV- (receive positive and negative) on the terminal block, again making careful note of which color is positive, and which color is negative.

Ultimately, you will want to construct a two pair cross over cable that makes a connection with the RS-485 device as shown below:

6.If there is a shield around the telephone cable, it may be connected to "G" on the terminal block. We recommend connecting the shield at the computer end only to avoid ground loops. A ground wire is not necessary for proper operation of the Model 2085.

7.When you finish connecting the wires to the terminal block, the assembly should resemble the diagram below:

+RCV- G -XMT+

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.
