The following describes the VP Gateway connections:
 USB Port – The PC is connected to the USB port to configure the keypads via a utility software
or terminal emulation program. The following functions are available via the USB port:
 Assign addresses to the keypads
 Add/delete/replace keypads in the system
 Set the Button-Type for each button according to application requirements
 Set the intensity level of the surrounding blue LEDs
 Set the timing parameters of each keypad for “short-press” and “double-press”
 Give a name/location to each keypad in the system
 Test communication with each keypad
 Select RS-232 or IP connectivity to the Host
 Set the IP parameters.
 RS-232 Port – The VP Gateway can connect to the Host via this port. The connector is a DB-9
female and only 3 wires are used for communication: Pin 2 is the TX of the VP Gateway, Pin 3 is
the RX of the VP Gateway, and Pin 5 is GND.
 Pin 2 connects to the RX of the Host.
 Pin 3 connects to the TX of the Host.
 Pin 5 connects to the GND of the Host.
The communication parameters are: 9600, N, 1.
Note: When the VP Gateway is configured to communicate with the Host via the RS-232 port,
the IP port is disabled.
 IP Port - The VP Gateway can connect to the Host via this port.
Note: When the VP Gateway is configured to communicate with the Host via the IP port, the RS-
232 port is disabled.
 RS-485 Port – The VP Gateway communicates with the VTouch Plus keypads via this port. Pins
A and B are connected via the 4-wire bus to Pins A and B of each keypad (A to A and B to B).
 Term – When a termination is required, a jumper is connected to the Term connector. An
internal 120 Ohm resistor will terminate the communication line.
 24 VDC – This is connected to the (+) and (-) terminals of the 24 VDC power supply and to the
two power wires of the 4-wire bus.
 LED Indications – There are three LEDs on the top panel of the VP Gateway:
 Power– Indicates that the 24 VDC is connected.
 Error – Lights up when there is a communication problem between the VP Gateway and at
least one of the VTouch Plus keypads.
 Data – Blinks when there is communication between the VP Gateway and the Host.
