Scope
This Supplement provides information on the new versions (Version CK) of the MICOM-2E/2RS/2TS
ALE HF-SSB transceivers. The new versions use enhanced hardware and provide additional ALE
capabilities.
Externally, the new versions are similar to the previous MICOM-2E/2RS/2TS ALE versions. However,
changes have been made in the wiring of the 44-pin accessories connector located on the rear panel,
relative to the 44-pin connector used by the previous versions.
The information appearing in this Supplement is intended for use with the following publications:
• Owner’s Guide, MICOM-2E/2RS/2TS ALE HF-SSB Transceivers, Publication
68P02952C60-A
• Supplement 68MB000010 to Owner’s Guide, MICOM-2E/2RS/2TS ALE HF-SSB
Transceivers.
New Model Information
The new transceiver versions have been assigned new model numbers, as follows:
MICOM-2ES Model M80AMNOKV5CK
MICOM-2ETS Model M81AMNOKV5CK
MICOM-2RS Model M85AMNOKV5CK

44-Pin Accessories Connector
Table 1 lists the current functions of the 44-pin accessories connector, J5.
Asterisks * appear in the
Designation
column next to the pins whose function has changed, relative
to previous equipment versions.
Notes
1. The information appearing in Table 1 supersedes any previous information
provided in the Owner’s Guide (Publication 68P02952C60-A) and in the
Supplement 68MB000010 to Owner’s Guide.
2. You can continue using the fixed adapter accessory for MICOM-2ES,
MICOM-2ETS and MICOM-2RS (part No. 09MB000011). This accessory
interfaces between the 44-pin connector and older 25-pin accessories.
