Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Getting Started 2 KRAMER: SIMPLE CREATIVE TECHNOLOGY
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.
Defining the VP-14xl RS-232 Port Extender 4 Defining the VP-14xl RS-232 Port Extender Figure 1 and Table 1 define the front and rear panels of the VP-14xl.
Connecting the VP-14xl RS-232 Port Extender 5 Connecting the VP-14xl RS-232 Port Extender 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 illustrates 1: 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.
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.
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).
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.
Serial Port Pinouts 8 Serial Port Pinouts Table 7 describes the pinouts of the 9-pin D-sub serial ports. Table 7: 9-Pin D-sub Serial Port Pinouts Pin 2 3 5 Function Receive Transmit Ground Note: Flow control signals are not supported. 9 Table of Hex Codes for Serial Communication (Protocol 2000) The RS-232/RS-485 Protocol 2000 uses four bytes of information as shown in Table 8. The data rate is set by the DIP-switches (see Table 5), with no parity, 8 data bits and 1 stop bit.
Table of Hex Codes for Serial Communication (Protocol 2000) O6…O0 – “OUTPUT”. When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched. Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was switched. For other operations, these bits are defined according to the table. 4th BYTE: Bit 7 – Defined as 1. Bit 5 – Don’t care. OVR – Machine number override. M4…M0 – MACHINE NUMBER.
