The serial communications port protocol can be switched in the CPU Unit’s
PC Setup. Depending on the protocol selected, the following systems can be
configured to support serial communications.
The Host Link System allows the I/O memory of the PC to be read/written,
and the operating mode to be changed from a host computer (personal com-
puter or Programmable Terminal) by executing Host Link commands. Other
Programming Devices can also be connected via a computer using this mode.
Alternatively, it is also possible to send data from the CPU Unit of the CQM1H
to the host computer using TXD(––) instructions to initiate communications
from the PC. This mode is supported by the peripheral port and the RS-232C
