RS-232/485 CONVERTER
3. Strip the insulation on each of the twisted- pair
wires about 1⁄8 inch.
Figure 4-2. Stripping the insulation on the twisted-pair wires.
4. In a two-pair circuit, 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
crossover cable that makes a connection with the
two Converters as shown in
Figure 4-3
