Chapter 3: Quick Start

3.5 - Serial Connection

To connect, power on, and test the PTU using the serial interface:

1. Connect the PTU as follows:

- Attach the DB25 to DB9 converter on one side of

the RS-232 to RS-485 converter.

- Attach one end of the four-pin RJ-11 phone cable

to the other side of the RS-232 to RS-485 adapter.

- Set the switches on the RS-232 to RS-485 con-

verter to T RxON and DCE.

- Attach the four-pin RJ-11 female-to-female

adapter to the other end of the phone cable. This

is important because the adapter rearranges the pins; the PTU will not function if the adapter is

not attached correctly.

- Connect the RS485 connector from the breakout cable into the adapter.

- Provide power to the converter through the included power supply.

- Alternatively, you can connect the USB to RS-485 cable (PTU-CONV-USB-RS485) to a USB port on

the host PC and the RJ-11 connector on the breakout cable.

2. Attach a standard RS-232 cable between a host PC and the DB9F connector on the PTU labeled RS-

232.

3. Open a terminal program such as HyperTerminal® or TeraTerm®.\

4. Create a new connection with the following communications

parameters:

- 9600 baud

-8 data bits

- 1 stop bit

-no parity

- no handshaking

Note: You may use simultaneous Ethernet and serial connections.

Note: HyperTerminal is available with Microsoft®

Windows XP® and previous versions. You may download

TeraTerm from http://ttssh2.sourceforge.jp/.
