Configuring the MCS-Spectrum as a Slave
When another MCS Series controller, such as the MCS-3800, is
directly connected to a host computer, the MCS-Spectrum
becomes a slave or expander peripheral. In this situation, the
MCS-Spectrum communicates indirectly with the host through the
master. The slave or expander MCS-Spectrum connects to the
master controller 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 slave or expander peripheral. In this case,
JB2 and JB3 in the MCS-Spectrum MUST be placed in the
“SLAVE” position. JB1 in the MCS-Spectrum MUST be
removed. The jumper for JB1 can be installed on one of the pins
of JB1 for safekeeping.
