APPENDIX F. FIRMWARE UPGRADE

F.1 Procedure
To perform a firmware upgrade on a Node or Supervisor, complete the following:
1) Power off the unit by moving the battery select switch to the "OFF" position (Figure 24), or
by disconnecting the external battery. (For units manufactured prior to June 2017, which do
not have an OFF position, remove the D cells from the battery holder.)
2) Ensure that the unit is completely discharged of electrical potential by pressing the status
button repeatedly until no LED lights flash.
3) For RS-232 Supervisors: Connect the 8001-7 USB to RS-232 adapter cable to the COM-
108 RS-232 to 10-pin cable. Continue to step four.
For all other Nodes/Supervisors: Connect the B8800-5 upgrade cable to the "RS232 J1"
connector on the bottom circuit board. (See Figure 25 for connector detail.)
