KRAMER: SIMPLE CREATIVE TECHNOLOGY

Getting Started

Overview

3 Overview

The unique VP-14xl RS-232 Port Extender distributes an incoming RS-232,

RS-485 or USB command as transmitted by a touch screen control system,

personal computer or other type of control system, to up to three RS-232 ports.

This lets you control up to three compatible devices with only one serial port or

RS-232 card.

The VP-14xl is specifically designed for use with Kramer switchers and routers,

but can be used with any other equipment which employs RS-232.

In particular, the VP-14xl features:

•One RS-232 input port

•One RS-485 input port

•One USB input port

•Three RS-232 output ports

•Operation in either Hardware or Software mode

•DIP-switches to determine the source of the reply command when the

VP-14xl is in hardware mode

•DIP-switches to determine the machine number when operating in Software

mode and there are multiple VP-14xl units on the RS-485 bus

•DIP-switches to determine the serial port baud rate (see Section 6.3)

In Hardware mode, the:

•VP-14xl routes the reply from the output port defined by the DIP-switches 2,

3 and 4 (see Section 6.2)

•RS-232 data is passed from any input to all outputs

In Software mode, the VP-14xl routes the data and reply based on the Protocol

2000 commands received from the PC or other device connected to any of the

inputs (RS-232, RS-485 or USB), see Section 8.

To achieve the best performance, we recommend:

•Connecting only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise levels

(often associated with low quality cables)

•Avoiding interference from neighboring electrical appliances that may

adversely influence signal quality and positioning your VP-14xl in a location

free from moisture and away from excessive sunlight and dust

Caution: No operator serviceable parts inside the unit

Warning: Use only the Kramer Electronics input power wall

adapter that is provided with the unit

Warning: Disconnect the power and unplug the unit from the wall

before installing

Figure 2: Connecting the VP-14xl RS-232 Port Extender

To connect your VP-14xl RS-232 Port Extender, as the example in Figure 2

illustrates1

1. Connect up to three computer sources to the input connectors (for example, 2

PCs and a laptop).

2. Connect up to three units to be controlled to the output connectors (for

example, Kramer switches).

3. If you are using the RS-485 input, set the RS-485 termination (see

Section 6.1).

1 Switch OFF the power on each device before connecting it to your VP-14xl. After powering up your VP-14xl, switch on the power to

each device

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Setting the DIP-switches on the VP-14xl

4. Set the Hardware/Software DIP-switch (see Section 6.4) as follows:

In Hardware mode, set the REPLY DIP-switches to determine the unique

reply output port (see Section 6.2)

In Software mode, set the machine number (see Section 6.2).

5. Set the serial port baud rate (see Section 6.3).

6. Select the appropriate machine number (see Section 6.2).

7. Connect the 5V DC power adapter to the 5V DC socket and to the mains

electricity.

Note: Changing any DIP-switch requires that you either power cycle

the VP-14xl or press the Reset button (see Table 1).

6 Setting the DIP-switches on the VP-14xl

Moving a DIP-switch down turns the switch on, moving it up turns the switch off.

Figure 3: VP-14xl DIP-switches

Table 2: VP-14xl DIP-switch Functions

DIP-switch # Function

1 RS-485 termination

2, 3, 4 In Hardware mode: Sets the reply source

In Software mode: Sets the machine number

5, 6, 7 Sets the serial port baud rate

8 Sets Software/Hardware mode

6.1 Setting the RS-485 Bus Termination

DIP-switch 1 sets the RS-485 bus termination. Only the first and last physical

device on the RS-485 bus must be terminated, all other devices must be un-

terminated.

When the DIP-switch is:

•OFF, the unit is un-terminated (default)

•ON, the unit is terminated

Setting the DIP-switches on the VP-14xl

6.2 Setting the ADDR DIP-switches

DIP-switches 2, 3 and 4 set either the reply source (in Hardware mode Table 3) or

machine number (in Software mode Table 4).

Table 3: Hardware Mode Reply Source DIP-switch Setting

Reply Source DIP-switch

2 3 4

Reply is taken from output 1 (default) ON OFF OFF

Reply is taken from output 2 OFF ON OFF

Reply is taken from output 3 OFF OFF ON

Note: When there is more than one VP-14xl attached to the RS-485 bus only one

unit can have a reply source set, all other units must have DIP-switches 2, 3 and 4

set to OFF.

3 OFF ON OFF 7 OFF ON ON

4 ON ON OFF 8 ON ON ON

When there is more than one VP-14xl attached to the RS-485 bus each unit must

have a unique machine number.

6.3 Setting the BAUD DIP-switches

DIP-switches 5, 6 and 7 set the serial port baud rate in both Hardware and

Software modes.

4800 OFF ON OFF 57600 OFF ON ON

9600 (default) ON ON OFF 115200 ON ON ON

6.4 Selecting Hardware/Software Mode

DIP-switch 8 sets the operating mode to either Hardware or Software mode.

When the DIP-switch is:

•OFF, the unit is set to Hardware mode (default)

•ON, the unit is set to Software mode

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Technical Specifications

6.5 Hardware Mode

In Hardware mode, the:

•RS-232 data is passed from any input to all outputs

•VP-14xl routes the reply from the output port defined by the DIP-switches 2,

3 and 4 (see Section 6.2). For reliable operation, only one port should be

defined

6.6 Software Mode

In Software mode, the VP-14xl routes the data and reply based on the Protocol

2000 commands received from the PC or other device connected to any of the

inputs (RS-232, RS-485 or USB), see Section 8.

Note: Only one reply port can be opened at a time. It is possible to open multiple

direct ports but only one reply port can be open at a time.

This means that if port1 is currently open and you then open port2, the port 1 is

automatically closed. If you then open port 1 again, port 2 is automatically closed.

In this way it is possible to close all reply ports, as well as all direct ports.
