Appendix C: RS232/RS485 Adaptor Cables
C-3
To extend the cable, you may use any extension cable with male and female D-type connectors
(connected pin-to-pin, not crossed).
Before transmitting, the RTU sends RTS=ON to the modem, and waits for CTS=ON from the
modem as a condition for transmitting.
The RTU will receive data from the modem only when DCD=ON.
When using a modem in auto-answer mode (connected to a Computer port) for remote service,
the RTU does not support RTS/CTS protocol since the port is designated to operate with a
local computer as well as with a modem.
For modems which support RS232-E, use either the RS232-E adaptor (#0189968V33) as in
Connection to IDEN Radio below, or the RS232-E+ adaptor (#0189968V34), as in Connection
to TETRA Radio below.
Connection to GPS Receiver
When an off-the-shelf GPS timing receiver is purchased (e.g. Synergy SynPaQ/E PPS Sensor
with M12+), the data and power cable for that receiver should be purchased as well.
Connect the data wire of the cable to the CPU port using the ACE3600 asynchronous RS232-E
adaptor cable. The port should be defined as a GPS receiver port (RS232, Async).
Connect the power wire of the cable to a cable with the following connectors:
RTU side: The connector should fit the auxiliary power connector on the ACE3600 power
supply module.
GPS Receiver side: The connector should fit the power connector on the GPS receiver cable.
Connecting a User Port to a Printer
To connect one of the RTU RS232 ports defined as a User port to a printer, you may use one of
the two cables described in the previous paragraphs. Since the connection to the printer is not
defined by the RS232 standard, every printer manufacturer has defined the connectors for his
own convenience. Therefore, select the adaptor according to the functions of the various pins.
If the FLN6458B adaptor (with the male 9-pin D-type connector) is used, refer to the following
table.
RS232 Function 9-pin Male Used as Direction
TX-DATA 3 Serial Data to Printer
CTS 8 Printer Ready from Printer
GND 5 GND -
If the FLN6457B adaptor (with the female 9-pin, D-type connector) is used, refer to the
following table.
RS232 Function 9-pin Female Used as Direction
RX-DATA 2 Printer Rx-Data to Printer
DTR 4 Printer Ready from Printer
GND 5 GND -
