Power is supplied to the modem through pins 38, 39 and 40.
Pin 39 must be supplied with 2.7 to 3.3 Volts and powers the digital and RF functional
entities of the modem. The modem has internal filtering circuitry to smooth out the
supply voltage but it has no onboard regulators.
All of the remaining pins of the modem are I/O lines of the processor, except for pin 50,
which is the RF I/O port.
The voltage on any of the I/O lines should never exceed VCC+0.3 V.
Pins 1 to 4 are attached to UART 2. Pins 5 to 8 are attached to UART1. If connecting to
the serial port of a PC, a level-shifting transceiver must be employed in order to provide
the appropriate voltage levels on the RX and TX lines.
Communication with the VN210 radio modem happens through serial port 1. The baud-
rate is set to be 115200, 8N1.
Open a terminal software on a serial port with the above settings and connect to the RF
modem. Upon power up, the terminal will display a list of the available commands.

To comply with FCC’s RF exposure limits for general population / uncontrolled exposure,
the antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
This Device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
1.
This device may not cause harmful interference, and
2.
This device must accept any interference received, including interference that
may cause undesired operation.
The VN210 RF Module has been certified per FCC Part 15 rules for integration into
products without further testing or certification. To fulfill the FCC certification
requirements the OEM of the VN210 RF Module must ensure that the information
provided on the VN210 RF Module label is placed on the outside of the final product.
The VN210 RF Module is labeled with its own FCC ID Number. If the FCC ID is not visible
when the module is installed inside another device, then the outside of the device into
which the module is installed must also display a label referring to the enclosed module.
This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID: 2AKZ5-CDSVN210ISA” or
“Contains FCC ID: 2AKZ5-CDSVN210ISA”
Only the approved antennas, which have been certified with this module should be
used. The approved antennas are:
ANT-2.4-CW-RCT-RP Linx Technologies (2.2dBi)
ANT-N-5 Mini-Box (5.5 dBi)
FS1-F9915KB Yokogawa (2.0 dBi)
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
