F. Ethernet Command Set
This appendix defines the Ethernet command set for both the Sample Changer and Start/Stop
AIM options.
F.1 Sample Changer Interface
The Sample Changer interface is Host controlled via the Ethernet Commands given below.
Ready Input and Advance Output signal polarities are host programmable. The default signals
are:
Ready Input – active TTL high.
Advance Output – active TTL Low.
Set Sample Changer Command (To AIM)
Channel
(0 = Channel 1, 1 = Channel 2)
Advance Polarity
(0 = non-invert, 1 = invert)
Ready Polarity
(0 = non-invert, 1 = invert)
Return Sample Changer Status (To AIM)
Channel
(0 = Channel 1, 1 = Channel 2)
Sample Changer Status Response (From AIM)
Advance Polarity
(0 = non-invert, 1 = invert)
Ready Polarity
(0 = non-invert, 1 = invert)
Ready Status
(0 = not ready, 1 = ready)
Advance Status
(0 = advance off, 1 = advance on)
Return Ready Status (To AIM)
Channel
(0 = Channel 1, 1 = Channel 2)
Ready Status Response (From AIM)
Status
(0 = Not ready, 1 = Ready)
Advance (To AIM)
Channel
State
(0 = Channel 1, 1 = Channel 2)
(1 = On, 0=Off)
F.2 Start/Stop Interface
The Start/Stop interface is a negative TTL edge signal.
Set Start/Stop Status Command (To AIM)
Channel
(0 = Channel 1, 1 = Channel 2)
State
(0 = none, 1 = start only, 2 = stop only, 3 = start/stop)
