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 particu

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. th 4 BYTE: Bit 7 – Defined as 1. Bit 5 – Don’t care. OVR – Machine
