The ending channel that supports voltage or 2-wire measurements.
end = slot[X].endchannel.voltage
[X]: Slot number (1 to 6)
This attribute will not exist for a slot if a card is not installed or the card installed does
not support voltage channels. In these cases, the return value will be nil. If supported,
the return value will be a number representing the ending channel. If only one channel
supports voltage then, the ending channel will match the starting channel number.
To query for ending voltage channel on Slot 4:
EndVoltageChan = slot[4].endchannel.voltage
Returns a string containing model number, description, firmware revision and serial
number of the card in slot X.
card_idn = slot[X].idn
[X]: Slot number (1 to 6)
Returns a comma separated string that contains the model number, description,
firmware revision and serial number of the card installed in slot X. This attribute will not
exist for a slot that does not have a card installed it unless that card has a pseudo card
assigned to it. If attribute does not exist, the return value will be nil.
For pseudocards, the response will be model number, description and firmware
revision. When queried, the return value will have "Pseudo" before the card
description. For example, if a Model 3720 Pseudocard is installed in Slot 3:
print(slot[3].idn)  3720,Pseudo Dual 1x30 Multiplexer,00.00a
To query for idn information for the card in Slot 1:
card1_idn = slot[1].idn
