BIT Connector
An 8-way RJ48 socket marked BIT used to connect BIT signals to associated parts of the system.
The pin-out is listed in Table 4-12.
The connector has an integral green indicator that lights when the Ready output is active.
Table 4-12 BIT Connector Pin-Out
Pin Signal Characteristics Input or Output
1 Ready
Open collector NPN transistor grounding output,
200 mA maximum. This signal is a low
impedance to ground when Ready is active, and
a high impedance to ground during a fault
condition.
Output
2 E-BIT (A) TTL input, active low. Input
3 E-BIT (B) TTL input, active low. Input
4 Not connected - -
5 Reserved TTL input, active low. Input
6 Reserved
Open collector NPN transistor grounding output,
200 mA maximum, normally open.
Output
7 Ground 0 V. -
8 Supply
When the radio is operating from an ac input, the
output is 24 Vdc (±1 V).
When the radio is operating from a dc input, the
output is between 20 and 32 Vdc.
The Supply output is fused at 500 mA.
