Notes

• Serial console port at 9-pin D-sub on rear panel; same pinout as PC COM port
• Handshake (RTS/CTS) enabled by default; can be defeated by jumpering pins 4&5 on mating connector
• Command line max: 126 characters including spaces; terminated by carriage return (0x0D)
• Multiple commands per line separated by semicolon
• Numeric prefixes: 0m forces decimal, 0x forces hexadecimal regardless of current base
• LTC 8300: supports 4 keyboards, 32 physical cameras, 288 index range, 6 monitors
• System prompt: TC8300> for LTC 8300 series
• Camera numbering: index (1–288 physical), physical (1–32 actual BNC), logical (any 4 digits, operator-facing)
• User numbers: 1–32 (index); assignable to any non-duplicate 3-digit logical user number
• +ALARM/-ALARM are ASCII commands (not R/C opcodes); separate from receiver/driver alarm handling
