DATA CONTROL
The following sections provide instructions and illustrations on how to connect numerous devices to the VMX200 for data control.
Each application shows a VMX200-SYS for illustration purposes only. You can also use a VMX200-SYS-1 or VMX200-SYS-Q.
NOTE: You can use either COM 1 or COM 2 on the VMX200 for control.
SPECTRA/ESPRIT CONTROL CONNECTIONS
To connect a Spectra or Esprit to a VMX200 for direct camera control, you must use a PV130 converter to convert the RS-232
interface to an RS-422 interface.
Follow these steps and refer to Figure 8:
1. Connect the RS-232 side of the PV130 converter to either COM 1 or COM 2 on the VMX200.
2. Use twisted pair wire to connect from TX+ and TX- on the PV130 converter to RX+ and RX- on the Spectra or Esprit. You
can daisy-chain from the RX+ and RX- connections on the first Spectra or Esprit to additional units.

Figure 8. Spectra/Esprit Control Connections
After you make the connections, open the Device Configuration window in the VMX200 software and add the receiver to your
system. Make sure you specify the following:
• Specify that the commands are sent via PC serial control port.
• Specify the D-Protocol driver.
• Select either “automatic” or “manual” camera addressing.
Refer to the VMX200 Software Installation/Operation Manual for detailed instructions on system configuration.
The receiver’s settings must match the VMX200 COM port settings. Refer to the Spectra/Esprit Installation/Operation Manuals
for instructions on setting baud rate, parity, and other settings.
