1.3.1 Channel number

To IT8700, the channel number for all modules is determined by the location of

the modules in relation to right side of the mainframe. To IT8702 mainframe, the

total channel number is 8. The 1

& 2

channel are always next to the right

mainframe while 7, 8 channels are always next to the left side. Load channel

number is fixed even if the location isn’t occupied. Load module could have one

or two channels. The channel number of single channel model from right to left

according to the slot position should be: 1

channel, 3

channel, 5

channel….

For module with dual channels, such as IT8722, the channel number should be:

1th and 2th channels, 3th and 4

channels, 5

and 6

channels… The figure

below displays the rule of the module channel number. IT8701P/IT8702P

mainframe and IT8703/IT8703P extended mainframe can be understood in the

same way.
