NTCIP Object Reference - Channel Parameters 17-24 (MM->1->3->2)

NTCIP 1202 defines CHANNEL PARAMETERS in section 2.9.   MAXIMUM CHANNELS is a "read-only" object that allows the manufacturer to set the maximum number of load switch channels driven by the controller (this value is fixed at 24 in Naztec's Ver 50 software).  The CHANNEL NUMBER is also a "read-only" object and is highlighted in red in the above menu (you cannot change this value).

This database objects for channels 17 - 24 in this table are identical to the database objects for channels 1-16 in MM->1->3->1. 

Ø / Olp#

2.9.2.2 CHANNEL CONTROL SOURCE PARAMETERS - The Channel Source Parameter and Channel Control Type (highlighted in yellow) combine to define each load switch output. This feature allows any phase, ped or overlap output to be mapped to any hardware output channel. Valid entries are 1-16 for phase, ped or overlap outputs or a value of "0" to make the channel inactive (or dark).

Type

2.9.2.3 CHANNEL CONTROL TYPE PARAMETERS - The Channel Source Parameter and Channel Control Type (highlighted in yellow) combine to define each load switch output.  The Channel Control Type parameter indicates the type of Control Source. The Control Source Type may be a Vehicle phase, Pedestrian phase, or an Overlap (VEH, PED, OLP).

Example - The example menu (highlighted in yellow) shows the default channel assignments for a Version 50 controller.  Vehicle phase outputs are mapped to channels 1-8.  Overlaps A - D (1-4) are mapped to channles 9-12.  Pedestrian outputs for phases 2-4-6-8 are mapped to channels 13-16.

Flash

2.9.2.4 CHANNEL FLASH PARAMETERS (bits 0-2)  The channel Flash parameter defines the channel's state during automatic flash. Select the color to flash (RED, YEL, DRK) and whether or not to flash on the alternate half hertz ('X' = YES). 

Alt Hz

2.9.2.4 CHANNEL FLASH PARAMETERS (bit 3) All channels programmed with an 'X' for alternate half hertz (ALT Hz) will flash together, and all channels programmed with a  ' . ' for Alt Hz will flash together.  Note that alternating the flash output puts less stress on the cabinet flasher.  

Example: The menu above alternates the flashing output between the left-turn phases (1-3-5-7) and the through phases (2-4-6-8) in a standard 8-phase quad left controller.

2.9.2.5 CHANNEL DIM PARAMETERS (bit 0-2)  The Dim Parameter determines which half of the 60 hertz AC cycle to turn off during dimming, and which colors to dim. Care should be taken that flashing is evenly distributed between the AC line cycle halves. Select DIM RED, DIM GRN, or DIM YEL for each output channel with an 'X' if you want this output dimmed.

Dim Cyc 

2.9.2.5 CHANNEL DIM PARAMETERS (bit 3).  This value indicates which half of the line cycle to use for dimming the outputs selected (specify a '+' or '-').
