Configuration
The SurveyorVFT must be configured for its address and mode and termination setting when using RS-
422/RS-485 protocol. The address and mode are set using the two 8-position DIP Switch banks SW1 and
SW2. It is necessary to determine which communication mode, Camera/Lens Module type and SurveyorVFT
address is required prior to configuration. Configuration should be performed just prior to final assembly and
installation. The termination setting is configured using 3 jumpers. This termination setting does not apply to
RS-422 mode.
Setting the DIP Switches
This section defines how to set DIP switches 1 and 2 (SW1 and SW2) on the Main Board.
Refer to Figure 22 for DIP switch location
and Figure 23 for DIP switch label. DIP
switch 1 (SW1) is used to set the address
as explained later. DIP switch 2 (SW2) is
used to set the mode functions and
protocol. Position 1 is the video mode
setting, NTSC (ON) or PAL (OFF).
Position 2 is the communication mode
setting, Vicoax mode (ON) or Serial (OFF).
Serial selection enables twisted pair
compatibility to other manufacturer’s
protocol. Position 3 is the communication
type setting, SIMPLEX (ON) or HALF
DUPLEX (OFF). Position 4 is the protocol
mode setting, RS-485 (ON) or RS-422
(OFF). Switches 5-8 select other
manufacturer’s protocols. Each switch is
numbered from 1 to 8 and marked to
indicate the ON position. SurveyorVFT will
automatically detect the system’s baud
rate and supports 4800, 9600 and 19,200
kb/sec rates.
For RS-422/485 Mode:
1. Set switches 1 - 8 on DIP switch 1
(SW1) to SurveyorVFT’s address as
specified in Table 3. All addresses between 0 and 255 are valid (address 0 is the same as camera
number 256). See Figure 23.

DIP Switch Location
2. Set switch 1 on DIP switch 2 (SW2) to the appropriate video mode (PAL/OFF or NTSC/ON).
3. Set switch 2 on DIP switch 2 (SW2) to the OFF position (SERIAL).
4. Set switch 3 on DIP switch 2 (SW2) to the appropriate communication mode (SIMPLEX or DUPLEX).
5. Set switch 4 on DIP switch 2 (SW2) to the appropriate communication protocol (RS-422 or RS-485).
6. Set switches 5-8 on DIP switch 2 (SW2) to the appropriate manufacturer protocol. See Figure 23.
NOTE: Switch 4 must be set to RS-485 protocol to enable daisy chain operation; switch 4 must be set to
RS-422 protocol to enable star operation.
NOTE: All SurveyorVFTs in a daisy chain or star configuration must have unique addresses for proper
operation.
For Vicoax Mode:
1. Set switch 1 on DIP switch 2 (SW2) to the appropriate video mode (PAL or NTSC).
2. Set switch 2 on DIP switch 2 (SW2) to the ON position (
Vicoax
mode).
3. Set switches 3 and 4 on DIP switch 2 (SW2) to either position, as it does not affect
Vicoax
protocol
operation.
