Specifying the Channel Mode
Contact closure cards operate in either pulse or presence mode. (Refer to the
Sensys Networks VDS240 Wireless Vehicle Detection System Reference Guide for
information about the operating modes.)
Follow these steps to specify the operating mode of the channel.
1. Position front-panel dip switch 7 to the left to select presence mode or to the
right to select pulse mode.
Figure 7.3. Selecting the channel operating mode with front-panel switch 7
2. Press the Enter button for five seconds to save the configuration to flash
memory or continue with other configuration activities described in this
section.
Setting a Presence Mode Modifier (Optional)
Channels operating in presence mode may use a modifier to delay the onset of or
extend the duration of a contact closure. The modifier type and scope is specified
using front-panel dip switches five and six together. (Refer to the Sensys
Networks VDS240 Wireless Vehicle Detection System Reference Guide for more
information.)
Using Delay and Extension
When Delay or Extension are specified, the rotary dial is used to articulate the
numeric value associated with the parameter.
When Delay is specified, the value set on the rotary dial is taken directly. This
allows the 16-step rotary switch to represent values from 0 to 15.
When Delay+16 is specified, the value set on the rotary dial is incremented by 16.
This allows the 16-step rotary switch to represent values from 16 to 31.
When Extension (EXTN / 2) is specified, the value set on the rotary dial is divided
by 2. This allows the 16-step rotary switch to represent values from 0 to 7.5 in ½
step increments.
Specify a contact closure delay or extension for channels operating in presence
mode by following these steps:
1. Position front-panel dip switches 5 and 6 and the front-panel rotary switch to
reflect the desired modifier and scope value. Use the figure below as a guide.
