Remote port configuration
The Remote port is a 3.5 mm, 5-pole captive screw connector for serial
RS-232/RS-422 control of the TPX 88. Wire the connector as shown in figure 2-7
and connect a host device, such as a computer, touch panel control, or RS-232
capable PDA.

RS-422 implementation may vary between computers or controls systems.
Connect the control cable as shown in figure 2-7. If the serial communications
link with the TPX switcher does not work, try reversing the polarity of the TX
and RX signal lines.
Set Remote Configuration DIP switches 1 and 2 either both down to select RS-422
serial control protocol or both up to select RS-232. DIP switch 3 should always be
up.
If desired, connect an MCP 1000 remote control panel master unit or MKP 2000 or
MKP 3000 remote control panel to the switcher’s Remote connector. You can also
connect an MKP 1000 remote keypad or MCP 1000 slave unit to the MCP 1000
master unit. Refer to the connected device’s manual for details.
See chapter 4, Programmer’s Guide, for definitions of the SIS commands and
chapter 5, Matrix Software for details on how to install and use the control software.
