ESP1100 INSTRUCTION MANUAL SUPPLEMENT
Upgrade and Operation of units for Base Station Data Capability
Rev A, April 9, 2001
1. Introduction
This supplement to the ESP1100 Instruction Manual (MAN-1100-01) describes the
upgrade, operation and modem level setting for Base Station data capability of the
ESP1100 100W repeater.
2. ESP1100 Upgrade
To upgrade an ESP1100 repeater for Base Station data operation, five (5) socketed chips
in the 1000 must be replaced:
C/I CPU PROM (U2) rev 2.01
TX CAN CPU (U2) rev 2.00
RX CAN CPU (U2) rev 2.00
TX CAN DSP PROM (U106) rev 2.00
RX CAN DSP PROM (U106) rev 2.00
In addition, transformer T2 on the C/I board must be removed and its input to output
terminals shorted on the board.
2. ESP1100 Operation
An ESP1100 outfitted with the above modifications (or units shipped from the factory
after June, 2001) include an operational mode called Base Station (a.k.a., BASESTN). In
this mode, base station modem equipment may be connected to the 1100 to permit the
radio to operate as a mobile data or AVL base station.
The interface between the modem and the 1100 is via the ACC2 connector. The pinout
is:
1100 ACC2 Pin Function
1 TXAF
2 RXAF
4PTT
12 GND

Page 12-3
BASESTN mode does not use an external trunking controller. In BASESTN mode, the
1100 transmits audio present at the ACC2 TXAF pin when keyed from ACC2. Received
audio is routed to the ACC2 RX AF pin. Half-second turnoff code bursts are transmitted
by the 1100 every 5,10, or 15 minutes to update mobile radio frequency tracking
memories.
An abbreviated version of the "Quickstart Procedure" from the 1100 manual page 6-40 is
given below, modified for DDS operation.
1. Determine RF Channel Numbers - same as in 1100 manual
2. Access Setup/Program Mode - same as in 1100 manual
3. Program Frequencies - same as in 1100 manual
4. Select BASESTN Operation:
a. Press 7# from the PM= prompt. Display is TRUNKED, CONVENTL, or
BASESTN.
b. Press 0 until display reads BASESTN.
5. Press #. Display is AREA=0 or AREA=1. Press 0 or 1 to select the proper area
bit for the repeater system.
6. Press #. Display is HOME=01,02, etc. Enter the normal home channel number
for the repeater.
7. Press #. Display is TOCRT=00,05,10, or 15.
Press 0 until the display reads the desired time interval (minutes) between
automatic turnoff code transmissions. Suggested value = 10 minutes. 00 = no
automatic turnoff codes.
8. Press #. Display is TOTE=N or Y.
Press 0 so display read TOTE=N. This disables the transmit timeout timer.
9. Press #, then 99#. Display is ESP1100 and unit is ready for operation in
basestation mode.

4. Modem Drive Levels
External modems connected to the ESP1000 should be adjusted for the following peak-
to-peak modulation drive levels input to the ACC2 TXAF pin:
Modulation Type Drive Level, Vpp
1200 bps MSK 400
1200 bps Bell 202 650
2400 bps GMSK 650
2400 bps BPSK 500
4800 bps QPSK 400
DDS 7200 bps 450
DDS 9600 bps 450
