BATS AND PORTABLE BATS OPERATION
3-80
3.7 RS-232C INTERFACE, BATS TRANSCEIVER
The BATS Transceiver uses the standard EIA RS-232C serial communications interface to com-
municate with other peripherals such as GPS TimeSync (COM1), heading or pitch/roll sensors. The-
se can be configured from the individual Devices setup dialog boxes. The interface to Trackman is
via the Ethernet port.
COM#1 “USBL to GPS Time”
COM1 is reserved for the GPS/TimeSync interface. To configure the GPS Time interface, from the
Project Tree select GPS/TimeSync from the Main menu go to USBL/GPS Time Sync. Set the BAUD
RATE, the number of DATA BITS required and the number of STOP BITS for the device in use. Con-
nect the COMMs Interface cable (9-pin DEC) between the Transceiver and the GPS device. Data
rate is limited to 16 Hz.
COM#2 or COM#3 “Sensor to USBL”
For a Heading device interface, select from the Project Tree “Heading Sensor” or from the Main
Menu go to SETUP/Compass Sensor. For a motion sensor, select from the Project Tree “Attitude
Sensor” or from the Main Menu go to SETUP/Attitude Sensor Setup. Data rate is limited to 16 Hz.
The NMEA mode allows input of various NMEA compass sentences or motion sensor sentences, with
or without checksum verification, “HDT”, “HDM”, “TCM-2” or “HDG” NMEA formats. Set up COM
port #2 for Compass input under the menu SETUP/COMPASS SETUP/TRACKPOINT (USBL). Select
Serial and then Port Settings. This allows the operator to configure the port’s Baud Rate, Data Bits
and Stop Bits.
ETHERNET Port
The BATS Transceiver’s RJ-45 is wired as a cross-over device so that interfaces directly to a PC. If
the ENET LED is illuminated on the front panel of the Transceiver then the hardware connection is
good. If communications cannot be established then check the PC’s IP address and subnet mask.
PC’s IP usually 192.168.3.X (X = anything but what the Transceiver’s address is. Subnet mask of
255.255.255.0. Port Number 50001. Other IP addresses can be set into the Transceiver, e.g., if
using a local network on a vessel. Contact EdgeTech for details.
3.7.1 HARDWARE
COM#1 “USBL Transceiver”
GPS/TimeSync - The Transceiver’s COM#1 interface is designed to act as a Data Terminal Equip-
ment (DTE) (E.g. Processor Module or PC), If interfacing to a module that has the same protocol, a
null modem is required between the two devices.
COM#2 “USBL Transceiver”
