Networking units
Before coupling units into a network:
 Each device must be configured with a unique Unit Identifier (letter A to Z)
however in multi drop systems it could be advised to avoid using letters A-F,
KMN and P as they could appear in the data string.
 Unit must be set for half duplex mode (E2 setting) see Para 7.3).
 It must be configured to a tri-state polled mode M3 or M4.
