TempScan / MultiScan User's Manual 889897 Expansion Unit 2-11
Channel Assignment
Channels 1 through 32 are always in the TempScan/1100, and channels 1 through 24 are always in the
MultiScan/1200, while the channels in the Exp/11A expansion unit are treated as extended channels. With
the first Exp/11A slave unit, the first channel in the first scanning card is channel 33 in the TempScan/1100
system, and channel 25 in the MultiScan/1200 system. With the same slave unit, the first channel in the
second scanning card is channel 65 in the TempScan/1100 system, and channel 49 in the MultiScan/1200
system. The order of multiple Exp/10A expansion units are set up using the rear panel DIP switches, as
described earlier.
Even if a scanning card slot is left empty in the master unit and/or slave unit(s), the channel assignments
remain the same, as shown in the table. For a 16-channel TempScan/1100 scanning card, the system still
assigns 32 channels to the card slot with the second 16 channels ignored. Likewise, for a 12-channel
MultiScan/1200 scanning card, the system still assigns 24 channels to the card slot with the second 12
channels ignored. For example, if a 16-channel TempRTD/16B scanning module is installed in the first slot
of Logical Unit 2 (the first Exp/10A), then channels 33 through 48 will be assigned and channels 49 through
64 will be ignored.
