JLCooper SX Midnight Eclipse - Manual (Page 6)

Configuring the MCS-Spectrum as a Master
When the MCS-Spectrum is directly connected to a host computer
using an interface card in Slot 1, it becomes the master. That is,
the MCS-Spectrum communicates directly with the host and any
other MCS Series controller become slave or expander peripherals.
Expander peripherals connect to the MCS-Spectrum using the
Expander port on the rear of the MCS-Spectrum.
The diagram below shows how to set the jumpers in the MCS-
Spectrum to operate as a Master. In this case, JB2 and JB3 in the
MCS-Spectrum MUST be placed in the “MASTER” position. JB1
in the MCS-Spectrum MUST be installed.
