Setting the DIP-switches on the TP-185

7 Setting the DIP-switches on the TP-185
The DIP-switches on the TP-185 perform the following functions:
• RS-485 termination
• Reply enable/disable
• Reply machine number
• Baud rate
• Hardware/software mode
Moving a DIP-switch down turns the switch on, moving it up turns the switch off.
Note: Changing any DIP-switch requires that you cycle power on the TP-185
7.1.1 Setting the RS-485 Bus Termination
The DIP-switch sets the RS-485 bus termination. Only the first and last physical
device on the RS-485 bus must be terminated, all other devices must be
un-terminated.
Figure 4: TP-185 DIP-switch RS-485 Termination
When DIP-switch 1 is:
• OFF, the unit is un-terminated (default)
• ON, the unit is terminated
Note: DIP-switch 2 is not used.
7.1.2 Enabling and Disabling the Reply Feature
DIP-switch 1 enables and disables the Reply feature.

- 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

- 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
