To connect RS-485 to a 25 pin serial port, a converter is required. Part number 117701 from Jameco

Electronics (www.jameco.com) is recommended. If the PC has a 9 pin serial port, a Jameco cable #31721 is
also required. Connect as follows:

adaptor drive

1

RX+

2

RX-

3 TX-

4 TX+

Set the switches for DCE, TxON, and RxON, then plug in the DC power adaptor that comes with the unit.

4 Figure #1 4-Wire RS-485.

The drive may also be connected to the host computer using only a 2-wire interface. First connect the

drive's TX+ to its RX+ and its TX- to its RX- before connecting to the Host adaptor. Usually RS-485 2-wire
interfaces are labeled “A” & “B”.

(Also see figure #2 below)

Getting and Connecting an RS-485 2-wire adaptor to your PC

For a 2-wire RS-485 connection, part number 485-25E from Integrity Instruments (www.rs-485.com)

is recommended. Connect as follows:

adaptor drive

B TX+/RX+

A TX-/RX-
