Logic “1” Output = Laser Fault. Logic “0” Output = Normal Operation 12 RD- Inverse Receiver Data Out 3 TX_Disable Logic “1” Input (or no connection) = Laser off, Logic “0” = Laser on. 13 RD+ Receiver Data Out 4 SDA Modulation Definition 2 – Two wires serial ID Interface 14 VEER Receiver Signal Ground 5 SDL Modulation Definition 1 – Two wires serial ID Interface 15 VCCR Receiver Power – 3.3V±5% 6 MOD-ABS Modulation Definition 0 – Ground in Module 16 VCCT Transmitter Power – 3.3V±5% 7 RS0 RX Rate Select (LVTTL). This pin has an internal 30k pulldown to ground. A signal on this pin will not affect module performance. 17 VEET Transmitter Signal Ground 8 RX_LOS Loss of Signal Out (OC). 18 TD+ Transmitter Data In 9 RS1 TX Rate Select (LVTTL). This pin has an internal 30k pulldown to ground. A signal on this pin will not affect module performance. 19 TD- Inverse Transmitter Data In 10 VEER Receiver Signal Ground 20 VEET Transmitter Signal Ground MODULE DEFINITION Module Definition PIN 4 PIN 5 PIN 6 Interpretation by Host 4 SDA SCL MOD-ABS Serial module definition protocol Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, SDA and SDL appear as no connector (NC) and MOD-ABS is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the 2-wire serial CMOS E 2PROM protocol of the ATMEL AT24C01A/02/04 family of components. |
