Serial Ports
Name Type Socket Typically used for…
PORT 1 RS-232 RJ-45(1) Local connection to PLC, data logger, meter
PORT 2 RS-232 RJ-45 Local connection to PLC, data logger, meter
CONFIG RS-232 RJ-45 Laptop, Analog output module
(1) Connector pins 2 and 3 are not connected on PORT 1.
(2) The +12V outputs can power small loads such as serial
converters.
Each port has a red/green LED indicator, which blinks green
when Topcat receives a valid message. Red indicates an error
condition.
Ethernet Port
This is a standard 100-base-T Ethernet port, which is operational when the
appropriate firmware is installed.
External Radio Connections
These connections are applicable only when no internal radio is fitted.

Communication Indicators
The COMMS indicators show communication between Topcat and the Telemetry
Master.
Indicator Indication Meaning
VAD/COMMS Green short blink A valid message for a different RTU was received
Green long blink A valid message for this RTU was received
Red Comms fail (no comms with the Master)
CHAN BUSY Yellow The radio transceiver is receiving RF on it’s channel
RX DATA Yellow Shows the data being received by Topcat
PTT Yellow Topcat is transmitting on the radio channel
TX DATA Yellow Shows the data being transmitted by Topcat
A short blink is about 0.1 seconds. A long blink is about 0.5 seconds.
Ready LED and Reset
Ready LED indication swampfox operating state
Green Normal Topcat is operating normally
Red Defect Hardware or firmware fault
The RESET button is behind a small unmarked hole in the front panel near the
DISPLAY button. To reset and restart Topcat, press RESET briefly.
Other Front Panel Items
The COMMS LED illuminates red when Topcat cannot communicate with a master.
The DISPLAY button turns the front panel indicators on and off. The ready LED is
always enabled.
The ADDRESS SWITCHES set Topcat’s three digit RTU address.
