COM128 Installation and Operation Manual

3 CONFIGURATION

3.1CONFIGURATIONSWITCHES

These six switches are used to configure the COM128 for the desired operation (see Figure 3.1.1). A switch is ON when it is in the UP position. The following is a description of each mode of operation. A list of switch settings for the different modes follows each mode description. The configuration switches are only read when control power is initally applied to the COM128. To re-configure the COM128, the control power must be removed and re-applied.

3.2MODE DESCRIPTIONS

3.2.1RS-485 FLOW CONTROL

FUNCTION

This mode is used to convert the RS-232 signals from either a DTE or DCE device to RS-485 signals. The COM128 makes the signal conversion and provides the timing control signals for the RS-485 ports. No data buffering takes place. Timing can be set for a fixed baud rate or the COM128 is able to do auto- matic baud rate detection on the incoming RS-232 data. Either the DTE or DCE port can be programmed. When the DTE port of the COM128 is selected in automatic baud rate detection mode, the input CD (Carrier Detect) signal from the DCE device can be used to control the transmission of RS-232 data from the COM128 to the DCE device.

For applications where a DTE device uses the RS-232 RTS signal for flow control the COM128 can be programmed to use the RTS signal to control the RS-485 ports.
