4.2 CONFIGURATION
All remote displays can be configured for operation with 8 to 16 electrodes (two LEDs per
electrode) or 18 to 32 electrodes (one LED per electrode). Remote displays are supplied
ready for operation with 8 to 16 electrodes. If a remote display is required to operate with 18
to 32 electrodes then it must be reconfigured. The procedure for each type of remote display
is described below.
4.2.1 RECONFIGURING THE 24683B AND 24683C REMOTE DISPLAY
The procedure for reconfiguring the 24683B and 24683C for operation with 18 to 32
electrodes is:
1. Undo the four screws securing the rear panel and remove the panel.
2. Withdraw the decoding PCB from the rear of the display unit. (Some force may be
necessary, initially, to disengage the decoding PCB from the LED PCB.)
3. Carefully remove the link headers from sockets LK2 and LK4 on the decoding PCB, by
easing them out with a suitable flat-bladed screwdriver. (See Figure 4.1)
4. Fit the link headers, removed in step 3, into sockets LK1 and LK3.
5. Refit the decoding PCB and the rear panel.

Note:
This figure shows the layout of the decoding pcb fitted to the 24683C and 24683D Remote
Displays. The layout of the decoding pcb in the 24683B Remote Display is slightly different, but the
arrangement of links LK1-LK4 is the same.
