3.1 Setting up Connections

PT-209G/219G modems are shipped from REnex with a pre-configured setting. They can operate

“out of the box”. Hence, the only thing users need to do is to make the appropriate connections

between the modem and their equipment via the RS-232 port, the USB port or the Ethernet port, and

then power up. The master and slave(s) shall communicate properly. For using the USB port, you

may need to install a driver for the first time plugging in your system. Please follow the

“Purpletooth® Family USB Driver Installation Guide” for the installation procedure.

3.2 Checking the Link

After finishing the physical connection setup mentioned above, PT-209G/219G should be ready. If

the performance of the communication link is not satisfactory or any linking problem is found, the

following steps may help you locate the problem.

Figure 3. Basic network mode.

1. Connect each modem to a serial port of a PC using direct RS-232 cable.

2. Start a terminal program such as Hyper Terminal (

http://www.hilgraeve.com, it may be

found in Microsoft Windows OS) for each serial port. Make sure the baud rate and data

format settings agree with those of PT-209G/219G.

3. Characters typed at the master’s terminal should appear at that of the slave’s and vice versa.

4. The TX LED should flash during transmitting data to the RF link.

5. The RX LED should flash during receiving data from the RF link.

6. Adjust the modem separation and the antenna direction to locate positions with the best

performance.

3. Setup PT-209G/219G

NOTE 2:

G/219G

is highly sensitive to obstacles in its

communication path. Make sure the communicating modems are in line

of-sight. Otherwise, the performance may drop significantly.

NOTE 3:

Antenna height is a critical factor. Try to put the antenna at a

position as high as possible.
