Serial Ports
Each of the two (or more) serial ports is configured as a DTE port using an RJ45 connector. This is the standard
recommended pinout for EIA/TIA-561 for 8 pin RJ45 connector:
PIN1
=RI
=RING INDICATOR, INPUT to the T850
PIN2
=DCD =CARRIER DETECT, INPUT to the T850
PIN3
=DTR =DATA TERMINAL READY, OUTPUT from the T850
PIN4
=SIGNAL GROUND
PIN5
=RXD =RECEIVED DATA, INPUT to the T850
PIN6
=TXD =TRANSMITTED DATA, OUTPUT from the T850
PIN7
=CTS =CLEAR TO SEND, INPUT to the T850
PIN8
=RTS =REQUEST TO SEND, OUTPUT from the T850
The DB9 female cable end which mates with the serial port connectors of connected devices will often have a pair of
screw-down cable screws. These cable screws should be used to assure a solid connection of the cable with the
device.
Default settings for the serial ports are 19200-baud, 8-bit word length, no parity, and one stop bit (19200, 8N1). Use
the internal setup menu to adjust these settings.
Internal Modem
If a dialup POTS modem is installed, an RJ11 (typical U.S. phone) connector is used. A POTS (analog) dialup phone
line is inserted into this connector. The modem installed within this unit is FCC certified. For further information,
consult the
appendix or the serial number label on the bottom of the T850.
CAUTION: To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
ATTENTION: Pour réduire les risques d’incendie, utilizer uniquement des conducteurs de télécommunications 26 AWG au
de section supérleure.
* Expansion Card Slots
Optional Expansion Cards can be installed to expand the capabilities of the T830-2 and T830-6. Contact Asentria
Sales (
) for more information on Expansion Cards.
DIP Switches
The bank of 8 DIP switches on the back panel of the T850 are used to control the baud and parity settings of I/O2, to
set
the operational mode for I/O2, and to put the unit into “boot load mode” where it can be forced to load a new
application (firmware image). The following table shows how to set the various DIP switches to obtain certain
settings:
