NTCIP Object Reference - Channel I/O Parameters (MM->1->3->3)

The following definitions were taken from the Naztec Version 50 Software Manual.  Object references are also provided based on NTCIP specification 1202 for each "read-write" data object present in the controller menu shown above.

NTCIP makes a distinction between "read-write" objects (data you can edit in the controller menu) and  "read-only" objects (constants that cannot be changed by the user).  For example, NTCIP object 2.2.1 MAXIMUM PHASES is a "read-only" object and is fixed at "16" for the Naztec 16 phase controller.  NTCIP 1202 defines the ACCESS attribute for each data object that governs the "read" and "write" access of the the object and whether it is accessible from protocol messages.

Chan 17-24 Mapping

Naztec MIB -  This parameter determines which output signals channels 17-24 are mapped to. Neither NEMA TS2 nor NTCIP define more than 16 output channels. 

D Conn Mapping

Naztec MIB -  The 'D' connector mapping entry defines the 'D' connector input/output pins. The following selections are currently available:

  • NONE        -  no inputs or outputs assigned to the D connector.

  • TX2-V14    -  Naztec Model 900-TX2CL, version 14

  • DIAMOND - Naztec Model 900-DIA6CL, version 6

Refer to the appendices for the D connector pin assignment for these model controllers.

Single T&F Biu Map

Naztec MIB -  TS2 Type 1 configuration that requires only one BIU for the traffic facility.

I/O Mode

 Naztec MIB -  The IO Modes are defined by NEMA as follows:
  • AUTO uses the default IO map for the TS2 and 2070 controller
  • Mode 0 - Mode 2 correspond with the TS2 IO Modes defined in TS2-1992, section 3.5.5.5. 
  • Modes 3-5 are reserved by NEMA for future use
  • Modes 6-7 are reserved for the manufacturer's use
  • USER mode is required to redefine the IO pins in the 2070 and 2070N version 50 software
  • NONE - this is a 2070 specific mode that disable the IO mapping

 
TOD DIMMING ENABLE 2.4.10 UNIT CONTROL (bit 7) - The TOD Dimming Enable must be set ON for any dimming to take place. Additionally, for dimming to be active, special function output x must be ON and the Dimming input signal must be asserted.
Prmpt/ExtCoor Out

Naztec MIB -  This parameter allows six of the external coordination outputs to be used as preempt active outputs, one per preempt.  A parameter under the preempt programming for each preempt determines during which preempt intervals the output is active.
C1-C11-ABC IO Mode Naztec MIB (2070 Only) - This setting allows the I/O to be remapped for the C1-C11 of the 2070 controller and the A-B-C connectors of the 2070N controller. 
  • NONE   Disables the I/O for the 2070 and 2070N controllers
  • AUTO  Applies the I/O standard published in the CALTRANS TEES Specification
  • Mode 0 – 7    Applies the NEMA I/O mode settings listed in Chapter 14 of this manual
  • USER   Applies USER I/O mapping programmed through MM->1->3->6 discussed below
