80188 Based CPU Card

Set serial port select ot RS-232. This is done by installing a jumper plug on E1
on the CPU Card to connect from the center pin to the RS-232 pin.

Set I/O Channel Check to disabled. This is done by installing a jumper plug
on E3 on the CPU Card to connect from the center pin to the DIS pin.

There must be a 32K static RAM chip installed in sockets RAM0 and RAM1.

There must be a 64K EPROM that contains the PLC gateway software
installed into socket ROM1.

There must be a 64K EPROM installed into socket ROM0.

Normally the PLC gateway will be mounted and wired on a MagneTek drive
panel. However, the gateway can be mounted remotely by the customer. In
this case, special consideration must be given to the 120 VAC power source for
the gateway power supply. DO NOT plug the gateway power cord directly
into a wall outlet. Instead, use an isolation transformer and tie one side of the
secondary to the nearest earth ground (the steel structure of the building is
usually a good choice). The ground studs on the MicroTrac drive panels or
cabinets must also be connected directly to a solid earth ground in order to
assure that the gateway enclosure and the drive panels are at the same
potential. Otherwise, erratic operation of the MicroTrac LAN system may
occur.
