PARAMETERS
No. Name Description
01 Reset Module Resets the adapter or sets the adapter parameters to factory default.
02 Comm Loss Action Sets the action that the adapter and drive will take if the adapter detects
a network failure.
03 Comm Loss Time Sets the communication loss timeout period (in seconds).
04 Flt Cfg Logic Sets the data that is sent to the drive if Parameter 02 - [Comm Loss Action]
05 Flt Cfg Ref is set to “Send Flt Cfg” and the adapter times out.
06 Baud Rate Cfg Sets the baud rate (kilobits per second) at which the adapter communicates.
07 Baud Rate Act Displays the baud rate (kilobits per second) actually used by the adapter.
08 MAC Address Displays the actual address selected by the MAC address switches
SW1 – SW7 on the adapter.
09 Max Master Sets the maximum MAC address for any device in the BACnet MS/TP token ring.
10 Max Info Frames Sets the maximum number of messages that the adapter can transmit while
it owns the token.
11 Device Inst Hi Sets the high-priority portion of the device instance number used by the adapter.
