Each Analogue Input card has up to 8 input channels for the Minitrend QX and the Mul-
titrend SX and up to 6 channels for the eZtrend
QXe. Connections are made via 2 x 12-
way screw terminal plugs that fit into a PCB header on the rear of the unit. The 2-way CJC
sensor should remain fitted in the central 2-way header.
The Minitrend QX
can have two analogue input cards fitted giving up to 16 input channels
(2 x 8 channel cards). The slot positions are A & B, these are identified on the rear panel on
the back of the unit. Either slot can be used, it is recommended that slot A is used if only one
card is fitted.
The Multitrend SX can have up to 6 analogue input cards fitted, up to 48 input channels.
The slot positions A, B, C, D, E or F; these are identified on the rear panel. PC boards are
fitted in order, slot ”A” starts from the top.
The eZtrend
QXe can use this card as an additional Analogue Input card fitted in Slot B,
providing up to 6 more channels. This card would be used after using the 3 or 6 channel
standard eZtrend
QXe Analogue Input card which is fitted in Slot A, see “QXe Analogue
Input (Standard) card” on page 19.
To fit this option card into the eZtrend QXe recorder you will require an expansion card to
