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.
