11.1 SAFETY PRECAUTIONS
This equipment has been designed and tested to the highest safety standards. The
following precautions should be covered to ensure safe operation of the apparatus.
11.2 TRANSPORTATION AND STORAGE
Careful inspection of the unit must be made after it has been subject to transportation or
storage. Any serious damage which could render it dangerous must be acted upon to
safeguard any potential user.
11.3 MAINS CONNECTOR AND PLUG
The supply lead plug shall only be inserted into a supply socket equipped with an earth
contact. Extension of the lead must include a suitable conductor for the protective earth.
This equipment must be earthed.
11.4 FUSES
Only the specified value and type of fuse must be fitted in the event of a replacement.
The brown supply lead (live) is fitted with a series fuse located in the mains connector
located on the rear panel and should the unit be fitted with a two pin plug then it is possible,
if the supply is reversed, for parts of the equipment to remain at supply potential after the
fuse has ruptured.
11.5 REMOVAL OF COVERS
Care must be exercised if the covers of the unit are removed. All internal live parts are
covered but the equipment should be disconnected from the supply source before repair or
maintenance.
Should it be necessary to carry out adjustments with the supply voltage connected then this
work must be done by suitably qualified personnel.
11.6 BAUD RATE
The unit is set to work at 38400 as default, but can be configured to operate at 115200 baud.
To change to this, the bottom link of J2 must be made (the link adapter must be de and re-
powered).
You can tell the current operating baud rate of the link adapter by turning the unit off and
back on. D3 will flash once for 38400 baud and twice for 115200 baud.
11.7 LOOP BACK TEST MODE
To confirm that the PC end is working, link J2 top link and re-power the link adapter. The
adapter will now echo any sent characters straight back. To use this, run up HyperTerminal
configured for 38400 (or 115200), eight bit, 1 stop, no parity, hardware flow control. Disable
local echo. Any characters typed should be echoed back to the screen.
Remember to unlink J2 when finished with the test.
