When dip switch 1 is up reply is disabled default down on reply is enabled 14
When there is more than one tp 185 attached to the rs 485 bus each unit must have a unique machine number 14
Dip switch 8 sets the operating mode to either hardware or software mode 15
Dip switches 5 6 and 7 set the serial port baud rate in both hardware and software modes according to table 4 note in a multiple device configuration all devices must be set to the same baud rate 15

Hardware mode 15
In hardware mode the rs 232 data is passed from any input to all outputs tp 185 routes the reply from the output port defined by the dip switches 2 3 and 4 see section 7 for reliable operation only one port can be defined 15

Instruction definition for specific instruction note 19
Note all values in the table are hexadecimal unless otherwise stated notes on table 9 note 1 when the pc sends this command if the instruction is valid the unit replies by sending the pc the same 4 bytes that it was sent except for the first byte where the destination bit is set high note 2 if o6 0 tx this command defines reads the definition of the output 1 2 or3 to pass the rs 232 direct command from any input in this case the instruction does not modify previously set output numbers allowing the setting of multiple outputs for the direct command if o6 1 rx the command defines reads the definition of the output 1 2 or 3 to pass the reply from the output to inputs in this case the instruction resets a previously set output number preventing the setting of multiple outputs for the reply note 3 the reply to this command is as follows the same command and output codes as were sent are returned and the input is assigned the value of the parameter that was read the reply is per the definit 19
