Serial protocol format for both RS232 and RS485 interfaces is set at no parity, 8 bit, 1
stop bit, no handshaking.
If using a Terminal mode protocol, the SSPA provides remote menu access through a
HyperTerminal program or through an actual hardware terminal.
The Ethernet interface is fixed to the 10Base-T standard. Normally, straight-through
CAT5 cable is used to connect the SSPA to a network hub, and crossover CAT5 is
used to connect directly to a computer’s Ethernet port.
J4 connector for RS232 utilizes standard DCE 9 pin pin-out (straight through cable re-
quires for connecting to remote PC RS232 port). For this interface maximum cable run
of 100 feet can be achieved for 9600 Baud and lower speed rates with quality ground
shield cable.
RS485 interface pin out is compatible with most 9 pin RS485 adapters. Interface al-
ways works in half-duplex mode and suitable for either 4 or 2 wire RS485 configura-
tion. Maximum achievable node length for this interface is 1500 feet. Proper termina-
tion and use of shielded twisted pair cable is required to achieve long cable runs.
Ethernet interface is auto selectable between 10 and 100 Mbit/s speeds. Maximum
node length is 100 feet. Use of CAT5E or CAT6 cables are preferred. CAT5 cable can
be used for 10Base-T standard or short runs of 100Base-T.
Digicor5 digital platform controller allows simulations support of multiple remote control
interfaces.
Table 9-1
shows a list of enabled interfaces depending on chosen interfaces setting.
Serial protocol is an independent selection and allows support of Normal or Terminal
mode protocols. Operation over IP interface remains unchanged regardless of serial
protocol selection.
