CHAPTER 3: Installation

3.1 Setting the Internal DIP Switches

Remove the cover of the Switch’s enclosure to
expose the PC board.

Figure 1 shows the location of the Code Operated

Matrix Switch’s internal DIP switches. There are two
types:

1. Individual Port Switches (see

Section 3.1.1

)

2. System Switches (these apply to all ports; see

Section 3.1.2

)

NOTE: DIP Switches may have different

designators to indicate the “ON” and “OFF”
settings. In this manual, “ON” is equivalent
to “Closed” and “OFF” is equivalent to
“Open.”

ONFIGURATIONS

A number of options can be configured for each
port individually. You can select:

• Baud rate: 110, 300, 600, 1200, 2400, 4800, 9600,

or 19,200 bps

• Parity: Even, odd, or none

• Data bits per word: 7 or 8

• Flow Control: Hardware (DTR/CTS) or software

(X-ON/X-OFF)

• Break detection: Break to disconnect or ignore

breaks
