Configuration
Housed in an ABS plastic case, the ME670A comes with either a male or female DB-
25 connector and both an RJ-11/RJ-45 combo jack and terminal blocks with strain
relief. The combo jack is pre-installed.
2. CONFIGURATION
The ME670A is simple to install and is ruggedly designed for excellent reliability: just
set it and forget it. The following instructions will help you set up and install the
ME670A properly. If you have any questions, don’t hesitate to call Black Box Technical
Support at [phone] or email to [e-mail].
2.1 CONFIGURATION SWITCHES
The ME670A uses a unique set of sixteen external DIP switches that allow configura-
tion to an extremely wide range of applications. These DIP switches are grouped into
two eight-switch sets and are externally accessible from the underside of the ME670A
(see Figure 1). There is no need to open the ME670A’s case for configuration.
The configuration switches allow you to select data rates, clocking methods, V.52 &
V.54 tests, word lengths, extended signaling rates, asynchronous or synchronous
mode and 2- or 4-wire mode. The drawings, text and tables on the following pages
describe all switch locations, positions and functions.
