Configure the Jameco adapter as follows:

• Set the switches for “DCE” and “TxON,RxON”

• Connect adapter pin 1 to drive terminal RX+

• Connect adapter pin 2 to drive terminal RX-

• Connect adapter pin 3 to drive terminal TX-

• Connect adapter pin 4 to drive terminal TX+

Another source of RS-485 adapters is B&B Electronics (815-433-5100 or www.bb-

elec.com). If your PC does not have an RS-232 serial port, B&B can supply you with

a USB to RS-485 converter.

If you plan to use more than one drive in your system, then connect the drives to each

other as follows:

• RX+ to RX+

• RX- to RX-

• TX+ to TX+

• TX- to TX-

• GND to GND

We recommend Category 5 wire, commonly used for ethernet networks. Maximum

distance from the host to any drive is 4000 feet. Because our drives transmit data at a

modest 9600 bits per second, no termination resistors are required.

The 1240i-485 will not work with the Si Programmer™ software. You need a standard

1240i for that. The only software on the Si™ CD that works with this drive is the SCL

Setup Utility.
