ACT-IR100SD host interface consists of three output signals and five input signals. All these signals are 
low active. That is, they are at 0V when active and at VCC level when inactive. When an inverting RS232 
level converter is used, the corresponding RS232 level signals are high active. That is, they are at +12V 
nominal when active and at –12V nominal when inactive. 
 

4.  /TXD: serial data output. 
2. /RXD: serial data input.   
3. /RTS: output. When hardware flow control is enabled. Active /RTS means /RXD is ready to 

receive. Inactive /RTS means /RXD is not ready. 

4. /CTS: input. If hardware flow control is enabled, /CTS must be driven active to allow /TXD and 

inactive to forbid /TXD. If hardware flow control is disabled, /CTS is optional. 

5. /DSR: input. If connection control is enabled, /DSR must be driven active to allow IrDA connection 

and inactive to forbid a new connection or terminate an existing connection. If connection control 
is disabled, /DSR is optional. 

6. /DTR: output. If connection control is enabled, active /DTR means an IrDA connection is made. 

Inactive /DTR means there is no connection. 

7. /CD: input. Optional. 
8. /RI: input. Optional.
