4.5 EEPROM Function Disable
Jumper SEL7 is use to enable or disable EEPROM function.
If this function disable, IR100S-L/LM will use SEL0~SEL4 setting only.
If this function enable, IR100S-L/LM will use EEPROM setting and jumpers SEL0~SEL4 are
ignored.
Note:
1. SEL5 ~ SEL6 are reserved for future use.
2. Independent of the SEL3 or SEL4, software flow control is automatically used and DTR
always active during IrLPT connection (this is used for printer host). In this case, if RXD
received an X-OFF, TXD transmission is blocked. If RXD received an X-ON, TXD
transmission may resume. In addition, hardware flow control may also be enabled.
3. For IrLPT, XON/XOFF flow control is always enabled. This is independent of SEL3 or
SEL4.
4. In IrCOMM 9-wire connection IR100S-L always response DCE line status if line state is
changed or response Poll for Line Settings via IrLMP control channel.
Independent of the IR flow control, HOST data flow control and baudrate is not obey
IrCOMM control parameters.
