60 MA CURRENT LOOP CONVERTER
3.1 Setting the DCE/DTE Switch
For your convenience, the Converter has an externally accessible DCE/DTE
switch. If the RS-232 device connected to the Converter is a modem or
multiplexor (or is wired like one), set the switch to “DTE.” This setting causes
the Converter to behave like Data Terminal Equipment and transmit data on
pin 2.
If the RS-232 device connected to the Converter is a PC, terminal or host
computer (or is wired like one), set the switch to “DCE.” This setting causes
the Converter to behave like Data Communications Equipment and transmit
data on pin 3.
