APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP Serial Module Identification—Read Only Use this area to find out about SNAP serial communication modules on the rack. The table shows the first two modules only; additional modules follow the same pattern, starting on even 10 hex boundaries. For important information on using these modules, see Opto 22 form 1191, the SNAP Serial Communication Module User’s Guide. Starting Address Length Type Description FFFF F03A 7F00 1 UI Serial module 0: Module hardware type. 0xF0 = SNAP-SCM-232 0xF1 = SNAP-SCM-485 0xF9 = SNAP-SCM-W2 FFFF F03A 7F01 1 UI Serial module 0: Module hardware subtype 0 = Modules manufactured before June 2003 1 = Modules manufactured June 2003 and after FFFF F03A 7F02 1 UI Serial module 0: Module hardware revision (month) FFFF F03A 7F03 1 UI Serial module 0: Module hardware revision (day) FFFF F03A 7F04 2 UI Serial module 0: Module hardware revision (year) FFFF F03A 7F06 4 UI Serial module 0: Module hardware loader revision FFFF F03A 7F0A 4 UI Serial module 0: Module hardware firmware revision FFFF F03A 7F0E 2 -- Pad for alignment FFFF F03A 7F10 1 UI Serial module 1: Module hardware type FFFF F03A 7F11 1 UI Serial module 1: Module hardware subtype FFFF F03A 7F12 1 UI Serial module 1: Module hardware revision (month) FFFF F03A 7F13 1 UI Serial module 1: Module hardware revision (day) FFFF F03A 7F14 2 UI Serial module 1: Module hardware revision (year) FFFF F03A 7F16 4 UI Serial module 1: Module hardware loader revision FFFF F03A 7F1A 4 UI Serial module 1: Module hardware firmware revision FFFF F03A 7F1E 2 -- Pad for alignment (Additional modules follow in order on even 10 hex boundaries.) Last valid address for this area: FFFF F03A 7FFA 110 SNAP Ethernet-Based I/O Units Protocols and Programming Guide
Serial Module Configuration—Read/Write Use this area to configure SNAP serial communication modules on the rack. Only two ports—the ports for a serial module in position 0 on the rack—are shown in the table. Ports for modules in other positions on the rack follow the same pattern and start on even 10 hex boundaries. See the table on page 112 for a list of module and port numbers. For important information on using these modules, see Opto 22 form 1191, the SNAP Serial Communication Module User’s Guide. Starting Address Length Type Description FFFF F03A 8000 4 UI Port A on serial module in position 0 on the rack: IP port number for access to serial port. Default is 22500. FFFF F03A 8004 4 UI Port A, position 0: Baud rate FFFF F03A 8008 1 UI Port A, position 0: Parity. None = 0x4E; even = 0x45; odd = 0x4F FFFF F03A 8009 1 UI Port A, position 0: Data Bits FFFF F03A 800A 1 UI Port A, position 0: Stop Bits FFFF F03A 800B 1 UI Port A, position 0: Hardware flow control. 1 = Yes, 0 = No FFFF F03A 800C 1 UI Port A, position 0: Send test message on powerup 1 = Yes; 0 = No FFFF F03A 800D 3 -- Pad for alignment FFFF F03A 8010 4 UI Port B on serial module in position 0 on the rack: IP port number for access to serial port. Default is 22501. FFFF F03A 8014 4 UI Port B, position 0: Baud rate FFFF F03A 8018 1 UI Port B, position 0: Parity FFFF F03A 8019 1 UI Port B, position 0: Data Bits FFFF F03A 801A 1 UI Port B, position 0: Stop Bits FFFF F03A 801B 1 UI Port B, position 0: Hardware flow control. 1 = Yes, 0 = No FFFF F03A 801C 1 UI Port B, position 0: Send test message on powerup FFFF F03A 801D 3 -- Pad for alignment (Additional ports follow in order on even 10 hex boundaries. See port table, below.) FFFF F03A 8200 4 UI Port A, position 0: End-of-message characters. The brain can check for a string of up to four characters as the end-of-message indicator. [Example: 0x0D0A0000 looks for a 13 (hex 0D) followed by a 10 (hex 0A)] FFFF F03A 8204 12 -- Pad for alignment SNAP Ethernet-Based I/O Units Protocols and Programming Guide 111
