D400 SUBSTATION GATEWAY INSTRUCTION MANUAL
The Fiber Optic Serial Adapter is available in two variants:
• Glass Optical Fiber (GOF) Serial with 820-850 nm ST connectors
(GE Item No. 520-0209LF)
• Plastic Optical Fiber (POF) Serial with 660 nm Agilent Versatile Link connectors (GE Item
No. 520-0210LF)
The plastic optical fiber is limited to 38.4 kbps operation and a lower operating
temperature limit of 0 °C.
The Fiber Optic Serial cards include two pairs of channels for signal transmission (TX1/TX2)
and reception (RX1/RX2) through ST (GOF) or Versatile Link (POF) connectors. The cards plug
into any serial communication slot (slots 1 through 8) on the D400.
The Fiber Optic Serial card supports the following configuration options for each channel:
• Standard state
• Inverted state
The state for each channel is selectable via a single two-position pin switch SW1 on the
Fiber Optic Serial card.
Follow instructions for setting the switch to select the appropriate state for each channel.
The fiber optic channel settings on the D400 must match the set up of the other end of the
fiber optic communications channel.
The factory default setting is Standard state on each channel.
Switch SW1 controls the state of each fiber optic channel. The switch contains four two-
position pins that can each be set to A or B to select the appropriate state.
