4 Operation of the LAAS Host Simulator
4.1 Connecting LAAS Receiver and LAAS Transmitter to LAAS Host Simulator PC
Refer to Appendix D for a pictorial representation of how the LAAS Host Simulator PC is connected to the LAAS
receiver and the LAAS transmitter.
Plug cables into the following ports on the LAAS Host Simulator PC:
•
The Counter I/O ISA card cable into the Counter I/O ISA card connector
•
A shielded RS-232 cable into COM 1
•
A shielded RS-232 cable into COM 2
Plug the cables from the LAAS Host Simulator PC into the Interface Box as follows:
•
Plug the unconnected end of the Counter I/O ISA Card cable into the connector labeled TIMER CARD
•
Plug the unconnected end of the COM 1 cable into the connector labeled COM 1 (TX)
•
Plug the unconnected end of the COM 2 cable into the connector labeled COM 2 (RX)
Plug cables into the following connectors on the Interface Box:
•
Plug a shielded RS-232 cable into the connector labeled J1 (RX)
•
Plug a shielded RS-232 cable into the connector labeled J1 (TX)
•
Plug a shielded RS-232 cable into the connector labeled J2 (RX)
•
Plug a shielded RS-232 cable into the connector labeled J2 (TX)
Plug the cables from the Interface Box into the LAAS Transmitter as follows:
•
Plug the unconnected end of the J1 (TX) cable into the port labeled J2 DATA I/O
•
Plug the unconnected end of the J2 (TX) cable into the port labeled J3 GPS TIME MARK
Presently there are two receivers that support the LAAS Receiver Command Protocol, the “standard product” LAAS
receiver and the LAAS Extended Sensitivity Receiver.
If the LHS will be used with the “standard product” LAAS receiver perform the following steps to plug the
cables from the Interface Box to the LAAS Receiver:
•
Plug the unconnected end of the J1 (RX) cable into the port labeled J2 DATA I/O
•
Plug the unconnected end of the J2 (RX) cable into the port labeled J3 GPS TIME MARK
If the LHS will be used with the LAAS Extended Sensitivity Receiver, perform the following steps to plug the
cables from the Interface Box to the LAAS Extended Sensitivity Receiver:
•
Obtain an adapter connector as described in Appendix C or an equivalent adapter connector and
plug the 25 pin D-Connector into the port labeled J3 DATA I/O
•
Plug the unconnected end of the J1 (RX) cable into the 9 pin D-Connector labeled DATA I/O
