Installing the U-AFA2M-CB Control Board
}Install only the U-AFA2M-CB AF control board in the BX-UCB control box. Remove any other Z-focusing control board
(U-ZPCB, U-AFP1-CB,etc.) if any is installed. Otherwise, malfunction will result.
# Do not unplug the termination connector. Otherwise, AF operation will be unavailable.
# The AF control board is a precision part that may be damaged critically by static electricity. Since the human
body is charged with a very small amount of static electricity, it should be discharged before handling the
board. The static electricity can be discharged by simply touching a nearby metallic object.

Changing the Settings of On-Board DIP Switches
}The on-board DIP switches on the AF control board have been set for
use with the BX61 before shipment from the factory.
In this condition, all switches of SW1, SW2 and SW3 are set to OFF.
When the AF Unit is Installed on the BX61
1. The DIP switches can be used without modifying the factory shipment
condition.
2. Change the DIP switch positions only when the following functions are
required.
SW2
Set No. 4 to ON.
· This replaces the functions of the F/C switching and stage escape
buttons on the left side of the BX61 with the stage DOWN and UP
functions.
SW3
Set No. 4 to ON.
· When the U-FWT filter wheel is not used, this changes the focus
adjustment stroke from 15 mm to 25 mm.
· Set the switch to OFF when the U-LWUCD long-WD universal
condenser is used.
When the AF Unit is Installed on the BXFMA
1. Be sure to change the settings of the DIP switches for the BXFMA.
SW2
Set No. 2 and No. 3 to ON.
SW3
Set No. 2 and No. 5 to ON*.
* This is required to align the focusing knob rotation directions with the
objective up/down movement directions when the U-FH is used. As
a result of this, rotating the focusing knob towards you move the
objective downward.
