Multiplexer Channel
Addresses
For the E1460A, the channel address (channel_list) has the form:
(@ssbc) for two-wire, three-wire, and four-wire operating modes
(@ss0hbc) for one-wire operating mode
(@ss099c) for control relays (all operating modes)
where
ss = card number (01-99)
0h = LO or HI terminal (0-1)
b = bank number (0-7)
c = number 0-7 for switching relays or 0-6 for control relays
Channel addresses can be specified in the following forms. The leading zero
in the card number can be ignored.
One-wire mode only
(@ss0hbc) for a single channel;
(@ss0hbc,ss0hbc) for multiple channels;
(@ss0hbc:ss0hbc) for sequential channels;
(@ss0hbc:ss0hbc,ss0hbc:ss0hbc) for groups of sequential channels
or any combination of the above.
Two-wire, three-wire, or four-wire modes (and control relays) where b = 099
(@ssbc) for a single channel;
(@ssbc,ssbc) for multiple channels;
(@ssbc:ssbc) for sequential channels;
(@ssbc:ssbc,ssbc:ssbc) for groups of sequential channels;
