Fitting the Serial Link Loom Assembly
In order to make a connection to an external device your detector control box will
require the fitting of a serial link loom assembly Loma part number 516517. The loom
connects between the 14 way header plug found on the serial link board, with the 16
way external connector located in the second from right gland hole when facing the
control box.
Fitting the 16 way external connector will require the drilling of 4 x 3mm clearance
holes to accommodate the connector fixing screws. It is suggested that the connector
be used as a template for marking out the hole positions prior to drilling. When
assembling, the connector cable is inserted through the gland hole, ensure the gasket
is located between the connector and the outside face of the control box. Secure with
the screws provided; screw heads to the outside.
Serial Link Wiring Tips
When connecting printers to your detector the following advice should be followed:
- Always use screened cable when making connections between any printer and
the detector. The screen should be a 360° Faraday shield type.
Do not create ground loops with the communication wiring down which earth
-
returns from electrical machinery could flow. Ideally the screen connection
should be made at one end only, normally at the source i.e. the detector.
