XTend-PKG-R™ RS-232/422/485 RF ModemConnect Hardware
To install the modem and test its range, you need:
* 2 XTend RF Modems. The two XTend RF Modems are referred to as "Radio1" and "Radio2".
* Accessories (Loopback adapter, RS-232 cable, 2 RPSMA antennas, 2 power supplies)
* 1 Windows PC loaded with X-CTU Software
1. Set both Radio DIP Switches to RS-232, point-to-point modes. [Switches 1 and 5 are ON (up), and the remaining 4 switches are OFF (down)].
2. C onnect the included RS-232 cable to the female DB-9 connector of Radio1 and the male DB-9 connector of the PC.
3. Attach the serial loopback adapter to the female DB-9 connector of Radio2. (The serial loopback adapter configures Radio2 to function as a repeater by looping data back into the module for retransmission, as shown.)
4. Attach RPSMA antennas to each RF modem.
5. Power Radio1 & Radio2 through their respective power connectors.Install Software
Go to the X-CTU Software page at www.digi.com/xctu and launch the legacy X-CTU installer (version 18.104.22.168).
