4) RS232 I/F DIAGNOSTICS
The program tests the RS232 interface for the main PWB and the
optional board ER-A5RS. Attach a 9-pin D-sub loop back connector
(UKOG-6717RCZZ) wired as shown in Fig. 3-11, to the port you are
going to test.

The following menu appears on screen. The cursor shown in reverse
video can be moved using the up/down arrow keys. Move the cursor
to the menu item you want to execute and select by pressing the
Enter key to the corresponding Diag. Program. Press the CANCEL
key to return the screen to this submenu.
When setting the channel for the RS232 interface, do not set more
than two ports to the same channel. The UP-600 accommodates up
to one ER-A5RS board, but use caution not to allow each port to
have the same channel; otherwise hardware might be destroyed.

When Diag. Is started, channel check is performed and only the
channels already set appear on screen.
4)-1. CHANNEL Check
Checking
The screen shows only the channels for which the channels of the
RS232 connect to the ECR. Compare the channels shown on
screen and the settings of channel setting DIPSW on the RS232
interface board.
The RS232 on the main PWB of the UP-600 is fixed to CH1 and
CH8. It is therefore necessary for the ER-A5RS to set the channel
to any of CH2 - CH7.
