Test of CTS/RTS
Check the [CTS] and [RTS] signals.
1. Jump each pin, 14(+RTS) and 19(+CTS), 17(-RTS) and 18(-CTS) of CN1.
2. The test is OK if the [CTS] lamp and the [RTS] lamp turn on at the same time that the [RTS] switch is
pressed. Similarly, the test is OK if the [CTS] turns off at the same time that the [RTS] is turned off.
Signal Test of RS-232C in MJ1 and MJ2
Select [MJ1] (or [MJ2]) and [RS-232C] in [Communication Port] by pressing each switch.
Loop-back Test
Check the [SD] and [RD] signals.
Execute the test by connecting the data transfer cable (ZM-80C) to CN1.
1. Set the adaptor, ADP25-9, which is attached to ZM-80C, to ZM-80C. And connect the modular jack
side of ZM-80C to MJ1 (or MJ2), ADP25-9 side of ZM-80C to CN1.
