Serial link wiring

The WIFI modem serial interface wiring is a two-step connection process:

First connect the modem to a PC to set up the modem configuration,

Then connect the modem to the final equipment for data transmission.

Connection during serial configuration phase

For the initial configuration phase, the WIFI modem has to be connected on

to a PC COM port. The set-up configuration software does not require

RTS/CTS wiring. The following scheme is an example of connection with a

PC:

+ DC Supply

Connection for data transmission

For the data transmission phase, the WIFI modem is attached by its serial

port to the final transmission equipment. If the hardware flow control has

been selected during modem configuration phase, RTS and CTS lines have to

be connected between both pieces of equipment.

The following scheme is an example where the modem is connected as a

piece of DCE equipment to a DTE with hardware flow control handshake:
