MTX-15
Dip Switches
The Dip Switches on the PCB are set as follows:
•
Switch 1:
Enables the termination resistor (ON position). When RS-
485 serial communications are used and the terminal is located at
the end of the serial chain, this switch should be ON. It should also
be ON for RS-232, Modem and Network terminals. For all RS-485
terminals except the last one, this switch should be OFF.
•
Switch 2:
Disables RS-485 communications (OFF position) in order
to permit firmware upgrades via RS-232 (serial models only). For
normal operation, this switch should always be in the ON position.
Note:
Firmware upgrades should never be attempted without consulting
Amano Technical Support for detailed instructions.
