Switches #7 and #8 perform the following functions:
Switch #7.........RS232 port selection switch. When “OFF” at unit startup, the
RS232 port will act as the serial console, regardless of the
port’s configuration or protocol assignment (refer to section 14
for more information on the serial console). When “ON” at unit
startup, the RS232 port carries whatever protocol (if any) was
assigned to it at configuration time. Note that the state of this
switch is only detected when the gateway boots up.
Switch #8.........Firmware update switch. Place in “OFF” position for normal
operation, and in the “ON” position only when new firmware is
to be downloaded to the unit. Refer to section 17 for more
information.
12. Auxiliary Power Supply
The ICC part #10456 120VAC/9VDC power supply can be used to power the
unit via the “POWER” input. If providing your own auxiliary power supply,
ensure that it adheres to the following specifications:
Connection diagram................
+
Voltage rating.......................... 9 - 40VDC
Current rating.......................... 500mA (@9VDC)
The gateway’s “POWER” input uses the CUI, Inc. PJ-002A (2.1mm x 5.5mm) or
equivalent DC power jack, which mates with the PP-002A (2.1mm x 5.5mm) or
equivalent power plug.
