8.15 T2000-A70 Data Modem Kit
The T2000-A70 conventional data modem allows a T2010 or T2015 radio to be used in
data applications, and also provides remote channel control via six BCD lines.
The command protocol and some test procedures are provided for those wanting to
write their own software. The protocol definition is based on the T2000 CCI protocol,
with specific extensions to support binary transmission and reception.
Note:
This interface is only compatible with radio firmware version 2.22, or later. If
you have a Series II HC05 logic PCB (PCB IPN 220-01377-0X), with v2.05 radio
firmware, contact your nearest authorised Tait dealer.
After upgrading from v2.05 radio software, it is necessary to change the link
resistors on the top side of the logic PCB. Remove link resistor #R714 and fit
#R714A.
