9.2.3 Knob Functions   
  Restore default settings: for all communication cards and work mode, you can cut the device power off and 
turn the knobs to the position F, and resupply the power. The AS00SCM-A module restores back to default 
setting once it is resupplied with power. This act does NOT affect the communication cards. Cut the power off 
again and turn the knobs to set the new values and then resupply the power. After that the ASSCCM00-A is set 
with new settings.   
  Modbus communication (AS-F232/AS-F422/AS-F485): can be installed in Card 1 and Card 2 (in COM mode 
only).   
1. Use the knob to set the node ID1 and ID2; its setting range is 0x01–0x0F.  You can use ISPSoft 
(HWCONFIG) to set up the node ID, if the knob is turned to 0. Follow the descriptions shown on the 
HWCONFIG for node ID setting range.

2. Modbus communication (AS-F232/AS-F422/AS-F485): can be installed in Card 1 and Card 2 (in COM 
mode only). Use the Format Knob to set the communication mode. You can use ISPSoft (HWCONFIG) to set up
