DIP SWITCH GENERAL DEFINITIONS
Table 4-1 displays the general DIP Switch settings. OFF (DOWN) = 0,
ON (UP) = 1
Note:
Use a tool with a
very small, pointed tip in
order to change the DIP
Switch positions.
Table 4-1 DIP Switch settings
Communication Modes
There are three communication modes for the RLPC - MODBUS
protocol, MR protocol and ASCII mode as shown in Table 4-2.
The DIP Switches must be set before the unit is powered up. If the DIP
Switches are changed, power cycle the instrument to implement the
change.
