1.3. CONET Layout

Thanks to Daisy chain capability, a single A2818 CONET controller can control up to 8
V2718 VME masters, while a single A3818 CONET2 controller (e.g. the 4-link model) an
control upt to 32 V2718 VME masters. For this purpose, various types of cables are
available:
Cable:
X-30
X-20
X-5
I-40
I-30
I-20
I-5
I-3
If the network is composed by one A2818, or A3818, and only one V2718, then it is
suggested to use X-type cables: such cables have a duplex connector on the A2818 or
A3818 side and two simplex connectors on the crate side; the simplex connector with the
black wrap is for the RX line and the one with the red wrap is for the TX. If more than one
V2718 is present, the best solution is to use the X-type cable for connecting the A2818,
or the A3818, with the first and the last module and the I-type for connecting intermediate
modules. An example using the A2818 is given in Fig. 2.
