Flow Control

Hardware flow control protocol requires a dedicated control line on the RS-232

cable. The dedicated control line is needed so that the device can signal the

controller when it is ready to receive data. You can designate either RTS/CTS or

DTR/DSR protocol for the RS-232 interface.

Set the XON switch for hardware control using the information in Table 2.4. With

hardware flow control selected, RS-232 Interface PCB jumpers J8 and J9 dictate

the type of flow protocol. Table2.5, “Jumper/Pin Settings for RTS/CTS Flow

Control (Default)” and Table2.6, “Jumper/Pin Settings for DTR/DSR Flow

Control (Default)” identify jumper connections and input and output pin

designations for each protocol. See also “Transmit / Receive Pin Selection” on

page 24 for RS-232 connector pinouts.

Note:When resetting the flow control switches during a working session, turn the

power supply OFF and then ON again to put the new settings into effect.
