Table 1–3 shows the clock probes and the 80C167 signal to which they must
connect for disassembly to be correct.

CK:3 BHE~=
CK:2 WR~=
CK:1 RD~=
CK:0 ALE=
= Indicates the channel is double probed
4. Align pin 1 or A1 of your test clip with the corresponding pin 1 or A1 of the
80C167 microcontroller in your SUT and attach the clip.
Applying and Removing Power
A power supply for the TMS 600 80C167 probe adapter is included with the
support. The power supply pr5 volts power to the probe adapter. The
center connector of the power jack connects to Vcc.
NOTE . Whenever the SUT is powered off, be sure to remove power from the probe
adapter.
To apply power to the 80C167 probe adapter and SUT, follow these steps:
CAUTION. Failure to use the +5 V power supply provided by Tektronix might
permanently damage the probe adapter and 80C167 microcontroller. Do not
mistake another power supply that looks similar for the +5 V power supply.
1. Connect the +5 V power supply to the jack on the probe adapter. Figure 1–6
shows the location of the jack on the adapter board.
CAUTION. Failure to apply power to the probe adapter before applying power to
your SUT might permanently damage the 80C167 microcontroller and SUT.
2. Plug the power supply for the probe adapter into an electrical outlet.
3. Power on the SUT.
