3. DIP Switch
The DIP switch is used to make various settings that determine who the PC
will operate. The C200HX/C200HG/C200HE CPU Unit has a 6-pin DIP
switch, as shown in the following diagram. The settings of these pins are
listed in the following table.
Pin no. Setting Function
1
ON Writing disabled for user memory.
OFF Writing enabled for user memory.

ON Standard communications parameters (see note) will be set for the following serial communications
ports.
• Built-in RS-232C port
• Peripheral port (only when a CQM1-CIF01/-CIF02 Cable is connected. Does not apply to Program-
ming Console.)
Note 1. Standard communications parameters are as follows:
Serial communications mode: Host Link or peripheral bus; start bits: 1; data length: 7 bits;
parity: even; stop bits: 2; baud rate: 9,600 bps
2. The CX-Programmer running on a personal computer can be connected to the peripheral
port via the peripheral bus using the above standard communications parameters.
OFF The communications parameters for the following serial communications ports will be set in PC
Setup as follows:
• Built-in RS-232C port: DM 6645 and DM 6646
• Peripheral port: DM 6650 and DM 6651
Note When the CX-Programmer is connected to the peripheral port with the peripheral bus, either set
bits 00 to 03 of DM 6650 to 0 Hex (for standard parameters), or set bits 12 to 15 of DM 6650 to 0
Hex and bits 00 to 03 of DM 6650 to 1 Hex (for Host Link or peripheral bus) separately.
6
ON Expansion TERMINAL mode for the Programming Console; AR 0712: ON
OFF Console mode for the Programming Console; AR 0712: OFF
Note All pins are set to OFF for the factory defaults.
4. Peripheral Port
The peripheral port is connected to peripheral devices, such as the Pro-
gramming Console.
5. RS-232C Port
The RS-232C port is connected to external devices that support an
RS-232C interface, such as personal computers.
