1-12
Section 1 — Introduction
Baud Rate and Data Format
The emulation mode used by the computer interface is set to VT100 or
compatible at the factory. The baud rate is set to 9600 with 8 data bits, 1 stop
bit, and no parity.
External Connections
The wiring of the connectors is different for RS232 and RS422.
The frame has been built to minimize RF emissions. It is important you use
tin and dimple D type connectors with metallized shells connected to the
shield of external cables in order to achieve low RF emissions from this
equipment. The shells are fixed with screwlocks with 4–40 UNC threads.
The RS232 Interface Cable
The interface connector on the router is a 9-pin D socket. The cable between
the PC and the router only needs to use TX, RX, and GND as shown in
Table 1-2.
NOTES: The SMS-6000 Configuration Editor requires an RS232 Connection.
Remote control can be performed with either the RS232 or the RS422 format.
