This section describes how to connect Swift DT500 to external devices.
3.1
Precautions
IMPORTANT: To connect Swift DT500 to a radio or a computer, use the cables
specially designed for Swift DT500 by Neocom Software, Ltd. Use of
any other cables not intended for Swift DT500 may cause damage to
Swift DT500 and to the hardware connected using a non-compliant
cable.
IMPORTANT: Connect Swift DT500 to a MOTOTRBO digital radio only when the
radio is powered OFF. When the radio is powered on, connecting or
disconnecting the cable presents a high risk of the USB interface
damage on the radio.
3.2
Connecting a Computer
Use the programming cable by Neocom Software, Ltd to connect the radio slot of
your Swift DT500 to a USB slot of a computer.

3.3
Connecting External Hardware
Swift DT500 provides interfaces for serial communication with external hardware and
VIO contacts that can be connected each to an external device for data input or
output. For instance, input VIO contacts can be used for monitoring states of
connected sensors, and output VIO contacts can be used for controlling external
hardware.
3.3.1
Connecting Swift DT500 for Serial Communication
To connect external hardware to serial ports RS-232/RS-485 of Swift DT500, use a
cable recommended by the hardware manufacturer. Connect external hardware only
when Swift DT500 is disconnected from the radio.
3.3.2
Connecting VIO Contacts for Input
An input VIO contact shall be connected to the ground (GND) to register ground
potential.
