Electrical style of I/O lines used as outputs

Values of this enumeration:

• TTL - The output line issues a TTL compliant signal
• ITTL - The output line issues an isolated TTL compliant signal actively tied to the high or low state
• IOC - The output line is an isolated TTL compliant signal actively tied to the low state and passively tied to the high state through a 3000 ohm pull-up resistor
• IOE - The output line is an isolated TTL compliant signal actively tied to the high state and passively tied to the low state through a 2000 ohm pull-down resistor
• RELAY - Parameter is not documented in Multicam documentation
• LED - Parameter is not documented in Multicam documentation
• OC - The output line issues a TTL compliant signal actively tied to the low state and passively tied to the high state
• LVDS - The output line is differential LVDS, RS-422 or RS-485 compatible
• DIFF - Parameter is not documented in Multicam documentation
• OPTO - The output line is an isolated photo transistor output
• SSRLY - The output line behaves as a solid-state relay
