2.0 Quick Start
This QUICK START guide will enable you to promptly establish basic connectivity between a pair of Nano
Series modems in a point-to-point (ref. 5.1) configuration.
2.1 Required Materials
•
2 Nano Series modules
•
2 Nano Series Interface Cards + 2 MHX Development Boards OR 2 Nano Motherboards, with
power adapters and Rubber Ducky Antennas
•
2 PCs with HyperTerminal (or equivalent) and 1 COM port each, or
1 PC with HyperTerminal and 2 COM ports
•
2 straight-through serial cables (9-pin M to 9-pin F)
2.2 Set-Up Procedure
•
Install Nano Series modules into the Nano Series Interface Cards and then into the MHX Devel-
opment Boards, or directly into the Nano Motherboard.
•
Connect straight-through cable from each Nano/MHX Development Board (rear ’RS-232’ port, the
“DATA” port) to the COM port of PC
(see section 3.4.1.2 for MHX Dev Board pin-outs or Section
3.5.2 for Nano Dev Board pin-outs).
This setup procedure uses the DATA port on the Nano, not
the Diagnostics port. Ensure you are connected to the correct port.
•
Open a HyperTerminal session for each Development Board connection, and configure it as
9600, 8 data bits, no parity, 1 stop bit, and no handshaking - then open the ‘connection’ (at bot-
tom left of HyperTerminal window, the word ‘Connected’ should appear).
•
Plug power adapter (8-30VDC) into wall outlet and, while depressing the CFG/CONFIG button on
the front of the Nano Motherboard/MHX Development Board, attach the ‘green’ connector of the
wall adapter cable to the rear connector; repeat with other MHX Development Board or Nano
Motherboard.
•
When the above step is performed, the HyperTerminal window should show the response ‘NO
CARRIER OK’.
•
At this point, both Nano Series modules are in COMMAND MODE. For one module (to be the
MASTER), type AT&F6 [Enter], then type AT&WA [Enter]. This module’s TX LED (red) should
now be illuminated. For the other module (to be the SLAVE), type AT&F7 [Enter], then type
AT&WA [Enter]. This module’s RX and 3 RSSI LED’s should illuminate.
•
We now have ‘radio’ connectivity. If text is entered in one PC’s HyperTerminal window, it should
appear in the other’s; and vice versa.
